Subject: [PATCH 48/69] mdadm: add CHANGELOG.md
|
||
|
|
|
||
|
|
Bring changelog back to life. Remove ANNOUCEs. It will use markdown
|
||
|
|
format, to have one style. All releases are migrated to new
|
||
|
|
changelog. It was a exercise I have taken, to familiarize with the
|
||
|
|
mdadm history.

-Subject: ANNOUNCE: mdadm 3.0 - A tool for managing Soft RAID under Linux
|
||
|
|
-
|
||
|
|
-I am pleased to (finally) announce the availability of
|
||
|
|
- mdadm version 3.0
|
||
|
|
-
|
||
|
|
-It is available at the usual places:
|
||
|
|
- countrycode=xx.
|
||
|
|
- http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
|
||
|
|
-and via git at
|
||
|
|
- git://neil.brown.name/mdadm
|
||
|
|
- http://neil.brown.name/git?p=mdadm
|
||
|
|
-
|
||
|
|
-
|
||
|
|
-This is a major new version and as such should be treated with some
|
||
|
|
-caution. However it has seen substantial testing and is considerred
|
||
|
|
-to be ready for wide use.
|
||
|
|
-
|
||
|
|
-
|
||
|
|
-The significant change which justifies the new major version number is
|
||
|
|
-that mdadm can now handle metadata updates entirely in userspace.
|
||
|
|
-This allows mdadm to support metadata formats that the kernel knows
|
||
|
|
-nothing about.
|
||
|
|
-
|
||
|
|
-Currently two such metadata formats are supported:
|
||
|
|
- - DDF - The SNIA standard format
|
||
|
|
- - Intel Matrix - The metadata used by recent Intel ICH controlers.
|
||
|
|
-
|
||
|
|
-Also the approach to device names has changed significantly.
|
||
|
|
-
|
||
|
|
-If udev is installed on the system, mdadm will not create any devices
|
||
|
|
-in /dev. Rather it allows udev to manage those devices. For this to work
|
||
|
|
-as expected, the included udev rules file should be installed.
|
||
|
|
-
|
||
|
|
-If udev is not installed, mdadm will still create devices and symlinks
|
||
|
|
-as required, and will also remove them when the array is stopped.
|
||
|
|
-
|
||
|
|
-mdadm now requires all devices which do not have a standard name (mdX
|
||
|
|
-or md_dX) to live in the directory /dev/md/. Names in this directory
|
||
|
|
-will always be created as symlinks back to the standard name in /dev.
|
||
|
|
-
|
||
|
|
-The man pages contain some information about the new externally managed
|
||
|
|
-metadata. However see below for a more condensed overview.
|
||
|
|
-
|
||
|
|
-Externally managed metadata introduces the concept of a 'container'.
|
||
|
|
-A container is a collection of (normally) physical devices which have
|
||
|
|
-a common set of metadata. A container is assembled as an md array, but
|
||
|
|
-is left 'inactive'.
|
||
|
|
-
|
||
|
|
-A container can contain one or more data arrays. These are composed from
|
||
|
|
-slices (partitions?) of various devices in the container.
|
||
|
|
-
|
||
|
|
-For example, a 5 devices DDF set can container a RAID1 using the first
|
||
|
|
-half of two devices, a RAID0 using the first half of the remain 3 devices,
|
||
|
|
-and a RAID5 over thte second half of all 5 devices.
|
||
|
|
-
|
||
|
|
-A container can be created with
|
||
|
|
-
|
||
|
|
- mdadm --create /dev/md0 -e ddf -n5 /dev/sd[abcde]
|
||
|
|
-
|
||
|
|
-or "-e imsm" to use the Intel Matrix Storage Manager.
|
||
|
|
-
|
||
|
|
-An array can be created within a container either by giving the
|
||
|
|
-container name and the only member:
|
||
|
|
-
|
||
|
|
- mdadm -C /dev/md1 --level raid1 -n 2 /dev/md0
|
||
|
|
-
|
||
|
|
-or by listing the component devices
|
||
|
|
-
|
||
|
|
- mdadm -C /dev/md2 --level raid0 -n 3 /dev/sd[cde]
|
||
|
|
-
|
||
|
|
-To assemble a container, it is easiest just to pass each device in turn to
|
||
|
|
-mdadm -I
|
||
|
|
-
|
||
|
|
- for i in /dev/sd[abcde]
|
||
|
|
- do mdadm -I $i
|
||
|
|
- done
|
||
|
|
-
|
||
|
|
-This will assemble the container and the components.
|
||
|
|
-
|
||
|
|
-Alternately the container can be assembled explicitly
|
||
|
|
-
|
||
|
|
- mdadm -A /dev/md0 /dev/sd[abcde]
|
||
|
|
-
|
||
|
|
-Then the components can all be assembled with
|
||
|
|
-
|
||
|
|
- mdadm -I /dev/md0
|
||
|
|
-
|
||
|
|
-For each container, mdadm will start a program called "mdmon" which will
|
||
|
|
-monitor the array and effect any metadata updates needed. The array is
|
||
|
|
-initially assembled readonly. It is up to "mdmon" to mark the metadata
|
||
|
|
-as 'dirty' and which the array to 'read-write'.
|
||
|
|
-
|
||
|
|
-The version 0.90 and 1.x metadata formats supported by previous
|
||
|
|
-versions for mdadm are still supported and the kernel still performs
|
||
|
|
-the same updates it use to. The new 'mdmon' approach is only used for
|
||
|
|
-newly introduced metadata types.

-This is a bugfix release over 3.1, which was withdrawn due to serious
|
||
|
|
-bugs. So it might be best to ignore 3.1 and say that this is a significant
|
||
|
|
-feature release over 3.0.x
|
||
|
|
-
|
||
|
|
-Significant changes are:
|
||
|
|
- - RAID level conversion between RAID1, RAID5, and RAID6 are
|
||
|
|
- possible were the kernel supports it (2.6.32 at least)
|
||
|
|
- - online chunksize and layout changing for RAID5 and RAID6
|
||
|
|
- where the kernel supports it.
|
||
|
|
- - reduce the number of devices in a RAID4/5/6 array.
|
||
|
|
-
|
||
|
|
- - The default metadata is not v1.1. This metadata is stored at the
|
||
|
|
- start of the device so is safer in many ways but could interfere with
|
||
|
|
- boot loaded. The old default (0.90) is still available and fully
|
||
|
|
- supported.
|
||
|
|
-
|
||
|
|
- - The default chunksize is now 512K rather than 64K. This seems more
|
||
|
|
- appropriate for modern devices.
|
||
|
|
-
|
||
|
|
- - The default bitmap chunksize for internal bitmaps is now at least
|
||
|
|
- 64Meg as fine grained bitmaps tend to impact performance more for
|
||
|
|
- little extra gain.
|
||
|
|
-
|
||
|
|
-This release is believed to be stable and you should feel free to
|
||
|
|
-upgrade to 3.1.1.

|
-This is a bugfix/stability release over 3.1.1.
|
||
|
|
-
|
||
|
|
-Significant changes are:
|
||
|
|
- - The default metadata has change again (sorry about that).
|
||
|
|
- It is now v1.2 and will hopefully stay that way. It turned
|
||
|
|
- out there with boot-block issues with v1.1 which make it
|
||
|
|
- unsuitable for a default, though in many cases it is still
|
||
|
|
- suitable to use.
|
||
|
|
- - Stopping a container is not permitted when members are still
|
||
|
|
- active
|
||
|
|
- - Add 'homehost' to the valid words for the "AUTO" config file
|
||
|
|
- line. When followed by "-all", this causes mdadm to
|
||
|
|
- auto-assemble any array belonging to this host, but not
|
||
|
|
- auto-assemble anything else.
|
||
|
|
- - Fix some bugs with "--grow --chunksize=" for changing chunksize.
|
||
|
|
- - VAR_RUN can be easily changed at compile time just like ALT_RUN.
|
||
|
|
- This gives distros more flexability in how to manage the
|
||
|
|
- pid and sock files that mdmon needs.
|
||
|
|
- - Various mdmon fixes
|
||
|
|
- - Alway make bitmap 4K-aligned if at all possible.
|
||
|
|
- - If mdadm.conf lists arrays which have inter-dependencies,
|
||
|
|
- the previously had to be listed in the "right" order. Now
|
||
|
|
- any order should work.
|
||
|
|
- - Fix --force assembly of v1.x arrays which are in the process
|
||
|
|
- of recovering.
|
||
|
|
- - Add section on 'scrubbing' to 'md' man page.
|
||
|
|
- - Various command-line-option parsing improvements.
|

|
|
- - ... and lots of other bug fixes.

|
-This is a bugfix/stability release over 3.1.2
|
||
|
|
-
|
||
|
|
-Significant changes are:
|
||
|
|
- - mapfile now lives in a fixed location which default to
|
||
|
|
- /dev/.mdadm/map but can be changed at compile time. This
|
||
|
|
- location is choses and most distros provide it during early

|
|
- boot and preserve it through. As long a /dev exists and is
|
||
|
|
- writable, /dev/.mdadm will be created.
|
||
|
|
- Other files file communication with mdmon live here too.
|
||
|
|
- This fixes a bug reported by Debian and Gentoo users where
|
||
|
|
- udev would spin in early-boot.
|
||
|
|
- - IMSM and DDF metadata will not be recognised on partitions
|
||
|
|
- as they should only be used on whole-disks.
|
||
|
|
- - Various overflows causes by 2G drives have been addressed.
|
||
|
|
- - A subarray of an IMSM contain can now be killed with
|
||
|
|
- --kill-subarray. Also subarrays can be renamed with
|
||
|
|
- --update-subarray
|
||
|
|
- - -If (or --incremental --fail) can be used from udev to
|
||
|
|
- fail and remove from all arrays a device which has been
|
||
|
|
- unplugged from the system. i.e. hot-unplug-support.
|
||
|
|
- - "mdadm /dev/mdX --re-add missing" will look for any device
|
||
|
|
- that looks like it should be a member of /dev/mdX but isn't
|
||
|
|
- and will automatically --re-add it
|

-3.1.3 had a couple of embarrasing regressions and a couple of other

-release after all.
|
||
|
|
-

-Two fixes related to configs that aren't using udev:

|
|
- - Don't remove md devices which 'standard' names on --stop
|
||
|
|
- - Allow dev_open to work on read-only /dev
|
||
|
|
-And fixed regressions:
|
||
|
|
- - Allow --incremental to add spares to an array
|
||
|
|
- - Accept --no-degraded as a deprecated option rather than
|
||
|
|
- throwing an error
|
||
|
|
- - Return correct success status when --incrmental assembling
|
||
|
|
- a container which does not yet have enough devices.
|
||
|
|
- - Don't link mdadm with pthreads, only mdmon needs it.
|
||
|
|
- - Fix compiler warning due to bad use of snprintf
|
||
|
|
- - Fix spare migration
|

|

|
|
- - Fixes for v1.x metadata on big-endian machines.
|
||
|
|
- - man page improvements
|
||
|
|
- - Improve '--detail --export' when run on partitions of an md array.
|

|
|
- - Fix regression with removing 'failed' or 'detached' devices.
|
||
|
|
- - Fixes for "--assemble --force" in various unusual cases.
|
||
|
|
- - Allow '-Y' to mean --export. This was documented but not implemented.
|
||
|
|
- - Various fixed for handling 'ddf' metadata. This is now more reliable
|
||
|
|
- but could benefit from more interoperability testing.
|
||
|
|
- - Correctly list subarrays of a container in "--detail" output.
|
||
|
|
- - Improve checks on whether the requested number of devices is supported
|
||
|
|
- by the metadata - both for --create and --grow.
|
||
|
|
- - Don't remove partitions from a device that is being included in an
|
||
|
|
- array until we are fully committed to including it.
|
||
|
|
- - Allow "--assemble --update=no-bitmap" so an array with a corrupt
|
||
|
|
- bitmap can still be assembled.
|
||
|
|
- - Don't allow --add to succeed if it looks like a "--re-add" is probably

|
|
-
|
||
|
|
-This is a "Developers only" release. Please don't consider using it
|
||
|
|
-or making it available to others without reading the following.
|
||
|
|
-
|
||
|
|
-
|
||
|
|
-By far the most significant change in this release related to the
|
||
|
|
-management of reshaping arrays. This code has been substantially
|
||
|
|
-re-written so that it can work with 'externally managed metadata' -
|
||
|
|
-Intel's IMSM in particular. We now support level migration and
|
||
|
|
-OnLine Capacity Expansion on these arrays.
|
||
|
|
-
|
||
|
|
-However, while the code largely works it has not been tested
|
||
|
|
-exhaustively so there are likely to be problems. As the reshape code
|
||
|
|
-for native metadata arrays was changed as part of this rewrite these
|
||
|
|
-problems could also result in regressions for reshape of native
|
||
|
|
-metadata.
|
||
|
|
-
|
||
|
|
-It is partly to encourage greater testing that this release is being
|
||
|
|
-made. Any reports of problem - particular reproducible recipes for
|
||
|
|
-triggering the problems - will be gratefully received.
|
||
|
|
-
|
||
|
|
-It is hopped that a "3.2.1" release will be available in early March
|
||
|
|
-which will be a bugfix release over this and can be considered
|
||
|
|
-suitable for general use.
|
||
|
|
-
|
||
|
|
-Other changes of note:
|
||
|
|
-
|
||
|
|
- - Policy framework.
|
||
|
|
- Various policy statements can be made in the mdadm.conf to guide
|
||
|
|
- the behaviour of mdadm, particular with regards to how new devices
|
||
|
|
- are treated by "mdadm -I".
|
||
|
|
- Depending on the 'action' associated with a device (identified by
|
||
|
|
- its 'path') such need devices can be automatically re-added to and
|
||
|
|
- existing array that they previously fell out off, or automatically
|
||
|
|
- added as a spare if they appear to contain no data.
|
||
|
|
-
|
||
|
|
- - mdadm now has a limited understanding of partition tables. This
|
||
|
|
- allows the policy framework to make decisions about partitioned
|
||
|
|
- devices as well.
|
||
|
|
-
|
||
|
|
- - --incremental --remove can be told what --path the device was on,
|
||
|
|
- and this info will be recorded so that another device appearing at
|
||
|
|
- the same physical location can be preferentially added to the same
|
||
|
|
- array (provides the spare-same-slot action policy applied to the
|
||
|
|
- path).
|
||
|
|
-
|
||
|
|
- - A new flags "--invalid-backup" flag is available in --assemble
|
||
|
|
- mode. This can be used to re-assemble an array which was stopping
|
||
|
|
- in the middle of a reshape, and for which the 'backup file' is no
|
||
|
|
- longer available or is corrupted. The array may have some
|
||
|
|
- corruption in it at the point where reshape was up to, but at least
|
||
|
|
- the rest of the array will become available.
|
||
|
|
-
|
||
|
|
-
|
||
|
|
- - Various internal restructuring - more is needed.

- - policy framework
|
||
|
|
- Policy can be expressed for moving spare devices between arrays, and
|
||
|
|
- for how to handle hot-plugged devices. This policy can be different
|
||
|
|
- for devices plugged in to different controllers etc.
|
||
|
|
- This, for example, allows a configuration where when a device is plugged
|
||
|
|
- in it is immediately included in an md array as a hot spare and
|
||
|
|
- possibly starts recovery immediately if an array is degraded.
|
||
|
|
-
|
||
|
|
- - some understanding of mbr and gpt paritition tables
|
||
|
|
- This is primarly to support the new hot-plug support. If a
|
||
|
|
- device is plugged in and policy suggests it should have a partition table,
|
||
|
|
- the partition table will be copied from a suitably similar device, and
|
||
|
|
- then the partitions will hot-plug and can then be added to md arrays.
|
||
|
|
-
|
||
|
|
- - "--incremental --remove" can remember where a device was removed from
|
||
|
|
- so if a device gets plugged back in the same place, special policy applies
|
||
|
|
- to it, allowing it to be included in an array even if a general hotplug
|
||
|
|
- will not be included.
|
||
|
|
-
|
||
|
|
- - enhanced reshape options, including growing a RAID0 by converting to RAID4,
|
||
|
|
- restriping, and converting back. Also convertions between RAID0 and
|
||
|
|
- RAID10 and between RAID1 and RAID10 are possible (with a suitably recent
|
||
|
|
- kernel).
|
||
|
|
-
|
||
|
|
- - spare migration for IMSM arrays.
|
||
|
|
- Spare migration can now work across 'containers' using non-native metadata
|
||
|
|
- and specifically Intel's IMSM arrays support spare migrations.
|
||
|
|
-
|
||
|
|
- - OLCE and level migration for Intel IMSM arrays.
|
||
|
|
- OnLine Capacity Expansion and level migration (e.g. RAID0 -> RAID5) is
|
||
|
|
- supported for Intel Matrix Storage Manager arrays.
|
||
|
|
- This support is currently 'experimental' for technical reasons. It can
|
||
|
|
- be enabled with "export MDADM_EXPERIMENTAL=1"
|
||
|
|
-
|
||
|
|
- - avoid including wayward devices
|
||
|
|
- If you split a RAID1, mount the two halves as two separate degraded RAID1s,
|
||
|
|
- and then later bring the two back together, it is possible that the md
|
||
|
|
- metadata won't properly show that one must over-ride the other.
|
||
|
|
- mdadm now does extra checking to detect this possibilty and avoid
|
||
|
|
- potentially corrupting data.
|
||
|
|
-
|
||
|
|
- - remove any possible confusion between similar options.
|
||
|
|
- e.g. --brief and --bitmap were mapped to 'b' and mdadm wouldn't
|
||
|
|
- notice if one was used where the other was expected.
|
||
|
|
-
|
||
|
|
- - allow K,M,G suffixes on chunk sizes
|
||
|
|
-
|
||
|
|
-
|
||
|
|
-While mdadm-3.2.1 is considered to be reasonably stable, you should
|
||
|
|
-only use it if you want to try out the new features, or if you
|
||
|
|
-generally like to be on the bleeding edge. If the new features are not
|
||
|
|
-important to you, then 3.1.5 is probably the appropriate version to be using
|
||
|
|
-until 3.2.2 comes out.

|
||
|
|
-
|
||
|
|
-This release is largely a stablising release for the 3.2 series.
|
||
|
|
-Many of the changes just fix bugs introduces in 3.2 or 3.2.1.
|
||
|
|
-
|
||
|
|
-There are some new features. They are:
|
||
|
|
- - reshaping IMSM (Intel metadata) arrays is no longer 'experimental',
|
||
|
|
- it should work properly and be largely compatible with IMSM drivers in
|
||
|
|
- other platforms.
|
||
|
|
- - --assume-clean can be used with --grow --size to avoid resyncing the
|
||
|
|
- new part of the array. This is only support with very new kernels.
|
||
|
|
- - RAID0 arrays can have chunksize which is not a power of 2. This has been
|
||
|
|
- supported in the kernel for a while but is only now supprted by
|
||
|
|
- mdadm.
|
||
|
|
-
|
||
|
|
- - A new tool 'raid6check' is available which can check a RAID6 array,
|
||
|
|
- or part of it, and report which device is most inconsistent with the
|
||
|
|
- others if any stripe is inconsistent. This is still under development
|
||
|
|
- and does not have a man page yet. If anyone tries it out and has any
|
||
|
|
- questions or experience to report, they would be most welcome on
|
||
|
|
- linux-raid@vger.kernel.org.
|
||
|
|
-
|
||
|
|
-Future releases in the 3.2 series will only be made if bugfixes are needed.
|
||
|
|
-The next release to add features is expected to be 3.3.

-This release primarily fixes a serious regression in 3.2.4.
|
||
|
|
-This regression does *not* cause any risk to data. It simply
|
||
|
|
-means that adding a device with "--add" would sometime fail
|
||
|
|
-when it should not.
|
||
|
|
-
|
||
|
|
-The fix also includes a couple of minor fixes such as making
|
||
|
|
-the "--layout=preserve" option to "--grow" work again.
|
||
|
|
-
|
||
|
|
-A reminder that the default location for runtime files is now
|
||
|
|
-"/run/mdadm". If you compile this for a distro that does not
|
||
|
|
-have "/run", you will need to compile with an alternate setting for
|
||
|
|
-MAP_DIR. e.g.
|
||
|
|
- make MAP_DIR=/var/run/mdadm
|
||
|
|
-or
|
||
|
|
- make MAP_DIR=/dev/.mdadm

- http://git.neil.brown.name/git/mdadm
|
||
|
|
-
|
||
|
|
-This is a major new release so don't be too surprised if there are a
|
||
|
|
-few issues. If I hear about them they will be fixed in 3.3.1.
|
||
|
|
-git log reports nearly 500 changes since 3.2.6 so I won't list them
|
||
|
|
-all.
|
||
|
|
-
|
||
|
|
-Some highlights are:
|
||
|
|
-
|
||
|
|
-- Some array reshapes can proceed without needing backup file.
|
||
|
|
- This is done by changing the 'data_offset' so we never need to write
|
||
|
|
- any data back over where it was before. If there is no "head space"
|
||
|
|
- or "tail space" to allow data_offset to change, the old mechanism
|
||
|
|
- with a backup file can still be used.
|
||
|
|
-- RAID10 arrays can be reshaped to change the number of devices,
|
||
|
|
- change the chunk size, or change the layout between 'near'
|
||
|
|
- and 'offset'.
|
||
|
|
- This will always change data_offset, and will fail if there is no
|
||
|
|
- room for data_offset to be moved.
|
||
|
|
-- "--assemble --update=metadata" can convert a 0.90 array to a 1.0 array.
|
||
|
|
-- bad-block-logs are supported (but not heavily tested yet)
|
||
|
|
-- "--assemble --update=revert-reshape" can be used to undo a reshape
|
||
|
|
- that has just been started but isn't really wanted. This is very
|
||
|
|
- new and while it passes basic tests it cannot be guaranteed.
|
||
|
|
-- improved locking between --incremental and --assemble
|
||
|
|
-- uses systemd to run "mdmon" if systemd is configured to do that.
|
||
|
|
-- kernel names of md devices can be non-numeric. e.g. "md_home" rather than
|
||
|
|
- "md0". This will probably confuse lots of other tools, so you need to
|
||
|
|
- echo CREATE names=yes >> /etc/mdadm.conf
|
||
|
|
- or the feature will not be used. (you also need a reasonably new kernel).
|
||
|
|
-- "--stop" can be given a kernel name instead of a device name. i.e
|
||
|
|
- mdadm --stop md4
|
||
|
|
- will work even if /dev/md4 doesn't exist.
|
||
|
|
-- "--detail --export" has some information about the devices in the array
|
||
|
|
-- --dump and --restore can be used to backup and restore the metadata on an
|
||
|
|
- array.
|
||
|
|
-- Hot-replace is supported with
|
||
|
|
- mdadm /dev/mdX --replace /dev/foo
|
||
|
|
- and
|
||
|
|
- mdadm /dev/mdX --replace /dev/foo --with /dev/bar
|
||
|
|
-- Config file can be a directory in which case all "*.conf" files are
|
||
|
|
- read in lexical order.
|
||
|
|
- Default is to read /etc/mdadm.conf and then /etc/mdadm.conf.d
|
||
|
|
- Thus
|
||
|
|
- echo CREATE name=yes > /etc/mdadm.conf.d/names.conf
|
||
|
|
- will also enable the use of named md devices.
|
||
|
|
-
|
||
|
|
-- Lots of improvements to DDF support including adding support for
|
||
|
|
- RAID10 (thanks Martin Wilck).
|
||
|
|
-
|
||
|
|
-and lots of bugfixes and other little changes.

-I am somewhat disappointed to have to announce the availability of
|
||
|
|
- mdadm version 3.3.4
|
||
|
|
-
|
||
|
|

- http://git.neil.brown.name/git/mdadm.git
|
||
|
|
-
|
||
|
|
-In mdadm-3.3 a change was made to how IMSM (Intel Matrix Storage
|
||
|
|
-Manager) metadata was handled. Previously an IMSM array would only
|
||
|
|
-be assembled if it was attached to an IMSM controller.
|
||
|
|
-
|
||
|
|
-In 3.3 this was relaxed as there are circumstances where the
|
||
|
|
-controller is not properly detected. Unfortunately this has negative
|
||
|
|
-consequences which have only just come to light.
|
||
|
|
-
|
||
|
|
-If you have an IMSM RAID1 configured and then disable RAID in the
|
||
|
|
-BIOS, the metadata will remain on the devices. If you then install
|
||
|
|
-some other OS on one device and then install Linux on the other, Linux
|
||
|
|
-might eventually start noticing the IMSM metadata (depending a bit on whether
|
||
|
|
-mdadm is included in the initramfs) and might start up the RAID1. This could
|
||
|
|
-copy one device over the other, thus trashing one of the installations.
|
||
|
|
-
|
||
|
|
-Not good.
|
||
|
|
-
|
||
|
|
-So with this release IMSM arrays will only be assembled if attached to
|
||
|
|
-an IMSM controller, or if "--force" is given to --assemble, or if the
|
||
|
|
-environment variable IMSM_NO_PLATFORM is set (used primarily for
|
||
|
|
-testing).
|
||
|
|
-
|
||
|
|
-I strongly recommend upgrading to 3.3.4 if you are using 3.3 or later.

|
||
|
|
+
|
||
|
|
+- Support for journalled RAID5/6 and clustered RAID1. This new support is probably still buggy.
|
||
|
|
+ Please report bugs.
|
||
|
|
+
|
||
|
|
+- There are also a number of fixes for **IMSM** support and an assortment of minor bug fixes.
|
||
|
|
+
|
||
|
|
+- I plan for this to be the last release of mdadm that I provide as I am retiring from MD and mdadm
|
||
|
|
+ maintenance. Jes Sorensen has volunteered to oversee mdadm for the next while. Thanks Jes!
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.3.4](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.3.4)
|
||
|
|
+
|
||
|
|
+**I strongly recommend upgrading to 3.3.4 if you are using 3.3 or later with IMSM.**
|
||
|
|
+
|
||
|
|
+- **IMSM** metadata assemble fixes.
|
||
|
|
+
|
||
|
|
+ In mdadm-3.3 a change was made to how **IMSM** metadata was handled. Previously an **IMSM** array
|
||
|
|
+ would only be assembled if it was attached to an **IMSM** controller. In 3.3 this was relaxed as
|
||
|
|
+ there are circumstances where the controller is not properly detected. Unfortunately, this has
|
||
|
|
+ negative consequences which have only just come to light.
|
||
|
|
+
|
||
|
|
+ If you have an IMSM RAID1 configured and then disable RAID in the BIOS, the metadata will remain
|
||
|
|
+ on the devices. If you then install some other OS on one device and then install Linux on the
|
||
|
|
+ other, Linux might eventually start noticing the IMSM metadata (depending a bit on whether
|
||
|
|
+ mdadm is included in the initramfs) and might start up the RAID1. This could copy one device over
|
||
|
|
+ the other, thus trashing one of the installations.
|
||
|
|
+
|
||
|
|
+ So, with this release IMSM arrays will only be assembled if attached to an **IMSM** controller,
|
||
|
|
+ or if **--force** is given to **--assemble**, or if the environment variable
|
||
|
|
+ **IMSM_NO_PLATFORM=1** is set (used primarily for testing).
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.3.3](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.3.3)
|
||
|
|
+
|
||
|
|
+- The 100 changes since 3.3.3 are mostly little bugfixes and some improvements to the self-tests.
|
||
|
|
+- raid6check now handle all RAID6 layouts including **DDF** correctly. See git log for the rest.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.3.2](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.3.2)
|
||
|
|
+
|
||
|
|
+- Little bugfixes and some man-page updates.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.3.1](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.3.1)
|
||
|
|
+
|
||
|
|
+- lots of work on **DDF** support.
|
||
|
|
+- Improved interactions with **systemd**. Where possible, background tasks are run from systemd
|
||
|
|
+ rather than forking.
|
||
|
|
+- Number of other little bug fixes too.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.3](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.3)
|
||
|
|
+
|
||
|
|
+- Some array reshapes can proceed without needing backup file. This is done by changing the
|
||
|
|
+ data_offset* so we never need to write any data back over where it was before. If there is no
|
||
|
|
+ 'head space' or 'tail space' to allow *data_offset* to change, the old mechanism with a backup
|
||
|
|
+ file can still be used.
|
||
|
|
+
|
||
|
|
+- RAID10 arrays can be reshaped to change the number of devices, change the chunk size, or change
|
||
|
|
+ the layout between *near* and *offset*.
|
||
|
|
+ This will always change *data_offset*, and will fail if there is no room for *data_offset* to be
|
||
|
|
+ moved.
|
||
|
|
+
|
||
|
|
+- **--assemble --update=metadata** can convert a **0.90** array to a **1.0** array.
|
||
|
|
+
|
||
|
|
+- **bad-block-logs** are supported (but not heavily tested yet).
|
||
|
|
+
|
||
|
|
+- **--assemble --update=revert-reshape** can be used to undo a reshape that has just been started
|
||
|
|
+ but isn't really wanted. This is very new and while it passes basic tests it cannot be
|
||
|
|
+ guaranteed.
|
||
|
|
+
|
||
|
|
+- improved locking between **--incremental** and **--assemble**.
|
||
|
|
+
|
||
|
|
+- uses systemd to run **mdmon** if systemd is configured to do that.
|
||
|
|
+- kernel names of md devices can be non-numeric. e.g. "md_home" rather than
|
||
|
|
+ "md0". This will probably confuse lots of other tools, so you need to
|
||
|
|
+ **echo CREATE names=yes >> /etc/mdadm.conf** or the feature will not be used (you also need a
|
||
|
|
+ reasonably new kernel).
|
||
|
|
+
|
||
|
|
+- **--stop** can be given a kernel name instead of a device name. i.e. **mdadm --stop md4** will
|
||
|
|
+ work even if /dev/md4 doesn't exist.
|
||
|
|
+
|
||
|
|
+- **--detail --export** has some information about the devices in the array.
|
||
|
|
+- **--dump** and **--restore** can be used to backup and restore the metadata on an array.
|
||
|
|
+- Hot-replace is supported with **mdadm /dev/mdX --replace /dev/foo** and
|
||
|
|
+ **mdadm /dev/mdX --replace /dev/foo --with /dev/bar**.
|
||
|
|
+
|
||
|
|
+- Config file can be a directory in which case all "*.conf" files are read in lexical order.
|
||
|
|
+ Default is to read **/etc/mdadm.conf** and then **/etc/mdadm.conf.d**. Thus
|
||
|
|
+ **echo CREATE name=yes > /etc/mdadm.conf.d/names.conf** will also enable the use of named md
|
||
|
|
+ devices.
|
||
|
|
+
|
||
|
|
+- Lots of improvements to **DDF** support including adding support for RAID10 (thanks Martin Wilck).

||
|
|
+# Release [mdadm-3.2.6](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2.6)
|
||
|
|
+
|
||
|
|
+- There are no real stand-out fixes, just lots of little bits and pieces.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.2.5](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2.5)
|
||
|
|
+
|
||
|
|
+- This release primarily fixes a serious regression in 3.2.4. This regression does *not* cause
|
||
|
|
+ any risk to data. It simply means that adding a device with **--add** would sometime fail
|
||
|
|
+ when it should not.
|
||
|
|
+- The fix also includes a couple of minor fixes such as making the **--layout=preserve** option to
|
||
|
|
+ **--grow** work again.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.2.4](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2.4)
|
||
|
|
+
|
||
|
|
+ - **--offroot** argument to improve interactions between mdmon and initrd.
|
||
|
|
+ - **--prefer** argument to select which */dev* names to display in some circumstances.
|
||
|
|
+ - relax restrictions on when **--add** will be allowed.
|
||
|
|
+ - Fix bug with adding write-intent-bitmap to active array.
|
||
|
|
+ - Now defaults to */run/mdadm* for storing run-time files.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.2.3](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2.3)
|
||
|
|
+
|
||
|
|
+- The largest single area of change is support for reshape of Intel IMSM arrays (OnLine Capacity
|
||
|
|
+ Expansion and Level Migration).
|
||
|
|
+- Among other fixes, this now has a better chance of surviving if a device fails during reshape.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.2.2](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2.2)
|
||
|
|
+
|
||
|
|
+- reshaping IMSM (Intel metadata) arrays is no longer 'experimental', it should work properly and be
|
||
|
|
+ largely compatible with IMSM drivers in other platforms.
|
||
|
|
+- **--assume-clean** can be used with **--grow --size** to avoid resyncing the new part of the
|
||
|
|
+ array. This is only support with very new kernels.
|
||
|
|
+- RAID0 arrays can have chunksize which is not a power of 2. This has been supported in the kernel
|
||
|
|
+ for a while but is only now supported by mdadm.
|
||
|
|
+
|
||
|
|
+- A new tool **raid6check** is available, which can check a RAID6 array, or part of it and report
|
||
|
|
+ which device is most inconsistent with the others if any stripe is inconsistent. This is still
|
||
|
|
+ under development and does not have a man page yet. If anyone tries it out and has any questions
|
||
|
|
+ or experience to report, they would be most welcome on linux-raid@vger.kernel.org.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.2.1](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2.1)
|
||
|
|
+
|
||
|
|
+- Policy framework
|
||
|
|
+
|
||
|
|
+ Policy can be expressed for moving spare devices between arrays, and for how to handle hot-plugged
|
||
|
|
+ devices. This policy can be different for devices plugged in to different controllers etc. This,
|
||
|
|
+ for example, allows a configuration where when a device is plugged in it is immediately included
|
||
|
|
+ in an md array as a hot spare and possibly starts recovery immediately if an array is degraded.
|
||
|
|
+
|
||
|
|
+- Some understanding of mbr and gpt paritition tables. This is primarily to support the new
|
||
|
|
+ hot-plug support. If a device is plugged in and policy suggests it should have a partition table,
|
||
|
|
+ the partition table will be copied from a suitably similar device, and then the partitions will
|
||
|
|
+ hot-plug and can then be added to md arrays.
|
||
|
|
+
|
||
|
|
+- **--incremental --remove** can remember where a device was removed from so if a device gets
|
||
|
|
+ plugged back in the same place, special policy applies to it, allowing it to be included in an
|
||
|
|
+ array even if a general hotplug will not be included.
|
||
|
|
+
|
||
|
|
+- Enhanced reshape options, including growing a RAID0 by converting to RAID4, restriping, and
|
||
|
|
+ converting back. Also convertions between RAID0 and RAID10 and between RAID1 and RAID10 are
|
||
|
|
+ possible (with a suitably recent kernel).
|
||
|
|
+
|
||
|
|
+- Spare migration for IMSM arrays. Spare migration can now work across 'containers' using
|
||
|
|
+ non-native metadata and specifically Intel's IMSM arrays support spare migrations.
|
||
|
|
+
|
||
|
|
+- OLCE and level migration for Intel IMSM arrays. OnLine Capacity Expansion and level migration
|
||
|
|
+ (e.g. RAID0 -> RAID5) is supported for Intel Matrix Storage Manager arrays. This support is
|
||
|
|
+ currently *experimental* for technical reasons. It can be enabled with
|
||
|
|
+ **export MDADM_EXPERIMENTAL=1**.
|
||
|
|
+
|
||
|
|
+- avoid including wayward devices.
|
||
|
|
+
|
||
|
|
+ If you split a RAID1, mount the two halves as two separate degraded RAID1s, and then later bring
|
||
|
|
+ the two back together, it is possible that the md metadata won't properly show that one must
|
||
|
|
+ over-ride the other. Mdadm now does extra checking to detect this possibility and avoid
|
||
|
|
+ potentially corrupting data.
|
||
|
|
+
|
||
|
|
+- Remove any possible confusion between similar options. e.g. **--brief** and **--bitmap** were
|
||
|
|
+ mapped to 'b' and mdadm wouldn't notice if one was used where the other was expected.
|
||
|
|
+
|
||
|
|
+- Allow K,M,G suffixes on chunk sizes.

||

+
|
||
|
|
+# Release [mdadm-3.2](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.2)
|
||
|
|
+
|
||
|
|
+- By far the most significant change in this release related to the management of reshaping arrays.
|
||
|
|
+ This code has been substantially re-written so that it can work with **externally managed
|
||
|
|
+ metadata** -Intel's IMSM in particular. We now support level migration and OnLine Capacity
|
||
|
|
+ Expansion on these arrays.
|
||
|
|
+
|
||
|
|
+- Various policy statements can be made in the *mdadm.conf* to guide the behavior of mdadm,
|
||
|
|
+ particular with regards to how new devices are treated by **--incremental**. Depending on the
|
||
|
|
+ *action* associated with a device (identified by its *path*) such need devices can be
|
||
|
|
+ automatically re-added to and existing array that they previously fell out off, or automatically
|
||
|
|
+ added as a spare if they appear to contain no data.
|
||
|
|
+
|
||
|
|
+- mdadm now has a limited understanding of partition tables. This allows the policy framework to
|
||
|
|
+ make decisions about partitioned devices as well.
|
||
|
|
+
|
||
|
|
+- **--incremental --remove** can be told what **--path** the device was on, and this info will be
|
||
|
|
+ recorded so that another device appearing at the same physical location can be preferentially
|
||
|
|
+ added to the same array (provides the spare-same-slot action policy applied to the path).
|
||
|
|
+
|
||
|
|
+- A new flags **--invalid-backup** flag is available in **--assemble** mode. This can be used to
|
||
|
|
+ re-assemble an array which was stopping in the middle of a reshape, and for which the
|
||
|
|
+ *backup file* is no longer available or is corrupted. The array may have some corruption in it
|
||
|
|
+ at the point where reshape was up to, but at least the rest of the array will become available.
|
||
|
|
+
|
||
|
|
+- Policy framework.
|
||
|
|
+- Various internal restructuring - more is needed.

+# Release [mdadm-3.1.5](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.1.5)
|
||
|
|
+
|
||
|
|
+- Fixes for **v1.x** metadata on big-endian machines.
|
||
|
|
+- man page improvements.
|
||
|
|
+- Improve **--detail --export** when run on partitions of an md array.
|
||
|
|
+- Fix regression with removing *failed* or *detached* devices.
|
||
|
|
+- Fixes for **--assemble --force** in various unusual cases.
|
||
|
|
+- Allow **-Y** to mean **--export**. This was documented but not implemented.
|
||
|
|
+- Various fixes for handling **ddf** metadata. This is now more reliable but could benefit from
|
||
|
|
+ more interoperability testing.
|
||
|
|
+- Correctly list subarrays of a container in **--detail** output.
|
||
|
|
+- Improve checks on whether the requested number of devices is supported by the metadata, both for
|
||
|
|
+ **--create** and **--grow**.
|
||
|
|
+- Don't remove partitions from a device that is being included in an array until we are fully
|
||
|
|
+ committed to including it.
|
||
|
|
+- Allow **--assemble --update=no-bitmap** so an array with a corrupt bitmap can still be assembled.
|
||
|
|
+- Don't allow **--add** to succeed if it looks like a **--re-add** is probably wanted, but cannot
|
||
|
|
+ succeed. This avoids inadvertently turning devices into spares when an array is failed.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.1.4](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.1.4)
|
||
|
|
+
|
||
|
|
+Two fixes related to configs that aren't using udev:
|
||
|
|
+- Don't remove md devices which 'standard' names on **--stop**.
|
||
|
|
+- Allow dev_open to work on read-only */dev*.
|
||
|
|
+
|
||
|
|
+And fixed regressions:
|
||
|
|
+- Allow **--incremental** to add spares to an array.
|
||
|
|
+- Accept **--no-degraded** as a deprecated option rather than throwing an error.
|
||
|
|
+- Return correct success status when **--incremental** assembling a container which does not yet
|
||
|
|
+ have enough devices.
|
||
|
|
+- Don't link mdadm with pthreads, only mdmon needs it.
|
||
|
|
+- Fix compiler warning due to bad use of snprintf.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.1.3](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.1.3)
|
||
|
|
+
|
||
|
|
+- mapfile now lives in a fixed location which default to */dev/.mdadm/map*, but can be changed at
|
||
|
|
+ compile time. This location is chosen and most distros provide it during early boot and preserve
|
||
|
|
+ it through. As long a */dev* exists and is writable, */dev/.mdadm* will be created. Other files
|
||
|
|
+ communication with mdmon live here too. This fixes a bug reported by Debian and Gentoo users where
|
||
|
|
+ udev would spin in early-boot.
|
||
|
|
+
|
||
|
|
+- IMSM and DDF metadata will not be recognized on partitions as they should only be used on
|
||
|
|
+ whole-disks.
|
||
|
|
+
|
||
|
|
+- Various overflows causes by 2G drives have been addressed.
|
||
|
|
+
|
||
|
|
+- A subarray of an IMSM contain can now be killed with **--kill-subarray**. Also, subarrays can be
|
||
|
|
+ renamed with **--update-subarray --update=name**.
|
||
|
|
+
|
||
|
|
+- **-If** (or **--incremental --fail**) can be used from udev to fail and remove from all arrays
|
||
|
|
+ a device which has been unplugged from the system i.e. hot-unplug-support.
|
||
|
|
+
|
||
|
|
+- **/dev/mdX --re-add missing** will look for any device that looks like it should be a member of
|
||
|
|
+ */dev/mdX* but isn't and will automatically **--re-add** it.
|
||
|
|
+
|
||
|
|
+- Now compile with *-Wextra* to get extra warnings.
|
||
|
|
+- Lots of minor bug fixes, documentation improvements, etc.
|
||
|
|
+
|
||
|
|
+# Release [mdadm-3.1.2](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.1.2)
|
||
|
|
+
|
||
|
|
+- The default metadata has change again (sorry about that). It is now **v1.2** and will hopefully
|
||
|
|
+ stay that way. It turned out there with boot-block issues with **v1.1** which make it unsuitable
|
||
|
|
+ for a default, though in many cases it is still suitable to use.
|
||
|
|
+
|
||
|
|
+- Add *homehost* to the valid words for the **AUTO** config file line. When followed by *-all*,
|
||
|
|
+ this causes mdadm to auto-assemble any array belonging to this host, but not auto-assemble
|
||
|
|
+ anything else.
|
||
|
|
+
|
||
|
|
+- VAR_RUN can be easily changed at compile time just like ALT_RUN. This gives distros more
|
||
|
|
+ flexibility in how to manage the pid and sock files that mdmon needs.
|
||
|
|
+
|
||
|
|
+- If mdadm.conf lists arrays which have inter-dependencies, the previously had to be listed in the
|
||
|
|
+ "right" order. Now, any order should work.
|
||
|
|
+
|
||
|
|
+- Fix some bugs with **--grow --chunksize=**.
|
||
|
|
+- Stopping a container is not permitted when members are still active.
|
||
|
|
+- Various mdmon fixes.
|
||
|
|
+- Alway make bitmap 4K-aligned if at all possible.
|
||
|
|
+- Fix **--force** assembly of **v1.x** arrays which are in the process of recovering.
|
||
|
|
+- Add section on 'scrubbing' to 'md' man page.
|
||
|
|
+- Various command-line-option parsing improvements.
|
||
|
|
+- ... and lots of other bug fixes.

|
|
+# Release [mdadm-3.1.1](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-3.1.1)
|
||
|
|
+
|
||
|
|
+- Multiple fixes for new **--grow** levels including fixes for serious data corruption
|
||
|
|
+ problems.
|
||
|
|
+- Change default metadata to **v1.1**.
|
||
|
|
+- Change default chunk size to 512K.
|
||
|
|
+- Change default bitmap chunk size to 64MB.
|
||
|
|
+- When **--re-add** is used, don't fall back to **--add** as this can destroy data.

+- Support **--grow** to change the layout of RAID 4/5/6.
|
||
|
|
+- Support **--grow** to change the chunk size of RAID 4/5/6.
|
||
|
|
+- Support **--grow** to change level from RAID1 -> RAID5 -> RAID6 and back.
|
||
|
|
+- Support **--grow** to reduce the number of devices in RAID 4/5/6.
|
||
|

|
||
|

+
|
||
|
|
+- Improvements for creating arrays giving just a name, like *foo*, rather than the full
|

|
|
+ */dev/md/foo*.
|
||
|
|
+- Improvements for assembling member arrays of containers.
|
||
|
|
+- Improvements to test suite.

+- Add option to change increment for *RebuildNN* messages reported by **--monitor**.
|
||
|
|
+- Improvements to **mdmon** hand-over from initrd to final root.
|
||
|
|
+- Handle merging of devices that have left an IMSM array and are being re-incorporated.

-Changes Prior to release 3.3
|
||
|
|
-- Some array reshapes can proceed without needing backup file.
|
||
|
|
- This is done by changing the 'data_offset' so we never need to write
|
||
|
|
- any data back over where it was before. If there is no "head space"
|
||
|
|
- or "tail space" to allow data_offset to change, the old mechanism
|
||
|
|
- with a backup file can still be used.
|
||
|
|
-- RAID10 arrays can be reshaped to change the number of devices,
|
||
|
|
- change the chunk size, or change the layout between 'near'
|
||
|
|
- and 'offset'.
|
||
|
|
- This will always change data_offset, and will fail if there is no
|
||
|
|
- room for data_offset to be moved.
|
||
|
|
-- "--assemble --update=metadata" can convert a 0.90 array to a 1.0 array.
|
||
|
|
-- bad-block-logs are supported (but not heavily tested yet)
|
||
|
|
-- "--assemble --update=revert-reshape" can be used to undo a reshape
|
||
|
|
- that has just been started but isn't really wanted. This is very
|
||
|
|
- new and while it passes basic tests it cannot be guaranteed.
|
||
|
|
-- improved locking between --incremental and --assemble
|
||
|
|
-- uses systemd to run "mdmon" if systemd is configured to do that.
|
||
|
|
-- kernel names of md devices can be non-numeric. e.g. "md_home" rather than
|
||
|
|
- "md0". This will probably confuse lots of other tools, so you need to
|
||
|
|
- echo CREATE names=yes >> /etc/mdadm.conf
|
||
|
|
- or the feature will not be used. (you also need a reasonably new kernel).
|
||
|
|
-- "--stop" can be given a kernel name instead of a device name. i.e
|
||
|
|
- mdadm --stop md4
|
||
|
|
- will work even if /dev/md4 doesn't exist.
|
||
|
|
-- "--detail --export" has some information about the devices in the array
|
||
|
|
-- --dump and --restore can be used to backup and restore the metadata on an
|
||
|
|
- array.
|
||
|
|
-- Hot-replace is supported with
|
||
|
|
- mdadm /dev/mdX --replace /dev/foo
|
||
|
|
- and
|
||
|
|
- mdadm /dev/mdX --replace /dev/foo --with /dev/bar
|
||
|
|
-- Config file can be a directory in which case all "*.conf" files are
|
||
|
|
- read in lexical order.
|
||
|
|
- Default is to read /etc/mdadm.conf and then /etc/mdadm.conf.d
|
||
|
|
- Thus
|
||
|
|
- echo CREATE name=yes > /etc/mdadm.conf.d/names.conf
|
||
|
|
- will also enable the use of named md devices.
|
||
|
|
-
|
||
|
|
-- Lots of improvements to DDF support including adding support for
|
||
|
|
- RAID10 (thanks Martin Wilck).
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2.6
|
||
|
|
- - There are no real stand-out fixes, just lots of little bits and pieces.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2.5
|
||
|
|
- - This release primarily fixes a serious regression in 3.2.4.
|
||
|
|
- This regression does *not* cause any risk to data. It simply
|
||
|
|
- means that adding a device with "--add" would sometime fail
|
||
|
|
- when it should not.
|
||
|
|
-
|
||
|
|
- - The fix also includes a couple of minor fixes such as making
|
||
|
|
- the "--layout=preserve" option to "--grow" work again.
|
||
|
|
-
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2.4
|
||
|
|
-"--oneline" log of changes is below. Some notable ones are:
|
||
|
|
-
|
||
|
|
- - --offroot argument to improve interactions between mdmon and initrd
|
||
|
|
- - --prefer argument to select which /dev names to display in some
|
||
|
|
- circumstances.
|
||
|
|
- - relax restructions on when "--add" will be allowed
|
||
|
|
- - Fix bug with adding write-intent-bitmap to active array
|
||
|
|
- - Now defaults to "/run/mdadm" for storing run-time files.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2.3
|
||
|
|
- - The largest single area of change is support for reshape of Intel
|
||
|
|
- IMSM arrays (OnLine Capacity Explansion and Level Migration).
|
||
|
|
- - Among other fixes, this now has a better chance of surviving if a
|
||
|
|
- device fails during reshape.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2.2
|
||
|
|
- - reshaping IMSM (Intel metadata) arrays is no longer 'experimental',
|
||
|
|
- it should work properly and be largely compatible with IMSM drivers in
|
||
|
|
- other platforms.
|
||
|
|
- - --assume-clean can be used with --grow --size to avoid resyncing the
|
||
|
|
- new part of the array. This is only support with very new kernels.
|
||
|
|
- - RAID0 arrays can have chunksize which is not a power of 2. This has been
|
||
|
|
- supported in the kernel for a while but is only now supprted by
|
||
|
|
- mdadm.
|
||
|
|
-
|
||
|
|
- - A new tool 'raid6check' is available which can check a RAID6 array,
|
||
|
|
- or part of it, and report which device is most inconsistent with the
|
||
|
|
- others if any stripe is inconsistent. This is still under development
|
||
|
|
- and does not have a man page yet. If anyone tries it out and has any
|
||
|
|
- questions or experience to report, they would be most welcome on
|
||
|
|
- linux-raid@vger.kernel.org.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2.1
|
||
|
|
- - policy framework
|
||
|
|
- Policy can be expressed for moving spare devices between arrays, and
|
||
|
|
- for how to handle hot-plugged devices. This policy can be different
|
||
|
|
- for devices plugged in to different controllers etc.
|
||
|
|
- This, for example, allows a configuration where when a device is plugged
|
||
|
|
- in it is immediately included in an md array as a hot spare and
|
||
|
|
- possibly starts recovery immediately if an array is degraded.
|
||
|
|
-
|
||
|
|
- - some understanding of mbr and gpt paritition tables
|
||
|
|
- This is primarly to support the new hot-plug support. If a
|
||
|
|
- device is plugged in and policy suggests it should have a partition table,
|
||
|
|
- the partition table will be copied from a suitably similar device, and
|
||
|
|
- then the partitions will hot-plug and can then be added to md arrays.
|
||
|
|
-
|
||
|
|
- - "--incremental --remove" can remember where a device was removed from
|
||
|
|
- so if a device gets plugged back in the same place, special policy applies
|
||
|
|
- to it, allowing it to be included in an array even if a general hotplug
|
||
|
|
- will not be included.
|
||
|
|
-
|
||
|
|
- - enhanced reshape options, including growing a RAID0 by converting to RAID4,
|
||
|
|
- restriping, and converting back. Also convertions between RAID0 and
|
||
|
|
- RAID10 and between RAID1 and RAID10 are possible (with a suitably recent
|
||
|
|
- kernel).
|
||
|
|
-
|
||
|
|
- - spare migration for IMSM arrays.
|
||
|
|
- Spare migration can now work across 'containers' using non-native metadata
|
||
|
|
- and specifically Intel's IMSM arrays support spare migrations.
|
||
|
|
-
|
||
|
|
- - OLCE and level migration for Intel IMSM arrays.
|
||
|
|
- OnLine Capacity Expansion and level migration (e.g. RAID0 -> RAID5) is
|
||
|
|
- supported for Intel Matrix Storage Manager arrays.
|
||
|
|
- This support is currently 'experimental' for technical reasons. It can
|
||
|
|
- be enabled with "export MDADM_EXPERIMENTAL=1"
|
||
|
|
-
|
||
|
|
- - avoid including wayward devices
|
||
|
|
- If you split a RAID1, mount the two halves as two separate degraded RAID1s,
|
||
|
|
- and then later bring the two back together, it is possible that the md
|
||
|
|
- metadata won't properly show that one must over-ride the other.
|
||
|
|
- mdadm now does extra checking to detect this possibilty and avoid
|
||
|
|
- potentially corrupting data.
|
||
|
|
-
|
||
|
|
- - remove any possible confusion between similar options.
|
||
|
|
- e.g. --brief and --bitmap were mapped to 'b' and mdadm wouldn't
|
||
|
|
- notice if one was used where the other was expected.
|
||
|
|
-
|
||
|
|
- - allow K,M,G suffixes on chunk sizes
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.2
|
||
|
|
- - By far the most significant change in this release related to the
|

|
|
- management of reshaping arrays. This code has been substantially
|
||
|
|
- re-written so that it can work with 'externally managed metadata' -
|
||
|
|
- Intel's IMSM in particular. We now support level migration and
|
||
|
|
- OnLine Capacity Expansion on these arrays.
|
||
|
|
- - Policy framework.
|
||
|
|
- Various policy statements can be made in the mdadm.conf to guide
|
||
|
|
- the behaviour of mdadm, particular with regards to how new devices
|
||
|
|
- are treated by "mdadm -I".
|
||
|
|
- Depending on the 'action' associated with a device (identified by
|
||
|
|
- its 'path') such need devices can be automatically re-added to and
|
||
|
|
- existing array that they previously fell out off, or automatically
|
||
|
|
- added as a spare if they appear to contain no data.
|
||
|
|
-
|
||
|
|
- - mdadm now has a limited understanding of partition tables. This
|
||
|
|
- allows the policy framework to make decisions about partitioned
|
||
|
|
- devices as well.
|
||
|
|
-
|
||
|
|
- - --incremental --remove can be told what --path the device was on,
|
||
|
|
- and this info will be recorded so that another device appearing at
|
||
|
|
- the same physical location can be preferentially added to the same
|
||
|
|
- array (provides the spare-same-slot action policy applied to the
|
||
|
|
- path).
|
||
|
|
-
|
||
|
|
- - A new flags "--invalid-backup" flag is available in --assemble
|
||
|
|
- mode. This can be used to re-assemble an array which was stopping
|
||
|
|
- in the middle of a reshape, and for which the 'backup file' is no
|
||
|
|
- longer available or is corrupted. The array may have some
|
||
|
|
- corruption in it at the point where reshape was up to, but at least
|
||
|
|
- the rest of the array will become available.
|
||
|
|
-
|
||
|
|
-
|
||
|
|
- - Various internal restructuring - more is needed.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.1.5
|
||
|
|
- - Fixes for v1.x metadata on big-endian machines.
|
||
|
|
- - man page improvements
|
||
|
|
- - Improve '--detail --export' when run on partitions of an md array.
|
||
|
|
- - Fix regression with removing 'failed' or 'detached' devices.
|
||
|
|
- - Fixes for "--assemble --force" in various unusual cases.
|
||
|
|
- - Allow '-Y' to mean --export. This was documented but not implemented.
|
||
|
|
- - Various fixed for handling 'ddf' metadata. This is now more reliable
|
||
|
|
- but could benefit from more interoperability testing.
|
||
|
|
- - Correctly list subarrays of a container in "--detail" output.
|
||
|
|
- - Improve checks on whether the requested number of devices is supported
|
||
|
|
- by the metadata - both for --create and --grow.
|
||
|
|
- - Don't remove partitions from a device that is being included in an
|
||
|
|
- array until we are fully committed to including it.
|
||
|
|
- - Allow "--assemble --update=no-bitmap" so an array with a corrupt
|
||
|
|
- bitmap can still be assembled.
|
||
|
|
- - Don't allow --add to succeed if it looks like a "--re-add" is probably
|
||
|
|
- wanted, but cannot succeed. This avoids inadvertently turning
|
||
|
|
- devices into spares when an array is failed.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.1.4
|
||
|
|
- Two fixes related to configs that aren't using udev:
|
||
|
|
- - Don't remove md devices which 'standard' names on --stop
|
||
|
|
- - Allow dev_open to work on read-only /dev
|
||
|
|
- And fixed regressions:
|
||
|
|
- - Allow --incremental to add spares to an array
|
||
|
|
- - Accept --no-degraded as a deprecated option rather than
|
||
|
|
- throwing an error
|
||
|
|
- - Return correct success status when --incrmental assembling
|
||
|
|
- a container which does not yet have enough devices.
|
||
|
|
- - Don't link mdadm with pthreads, only mdmon needs it.
|
||
|
|
- - Fix compiler warning due to bad use of snprintf
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.1.3
|
||
|
|
- - mapfile now lives in a fixed location which default to
|
||
|
|
- /dev/.mdadm/map but can be changed at compile time. This
|
||
|
|
- location is choses and most distros provide it during early
|
||
|
|
- boot and preserve it through. As long a /dev exists and is
|
||
|
|
- writable, /dev/.mdadm will be created.
|
||
|
|
- Other files file communication with mdmon live here too.
|
||
|
|
- This fixes a bug reported by Debian and Gentoo users where
|
||
|
|
- udev would spin in early-boot.
|
||
|
|
- - IMSM and DDF metadata will not be recognised on partitions
|
||
|
|
- as they should only be used on whole-disks.
|
||
|
|
- - Various overflows causes by 2G drives have been addressed.
|
||
|
|
- - A subarray of an IMSM contain can now be killed with
|
||
|
|
- --kill-subarray. Also subarrays can be renamed with
|
||
|
|
- --update-subarray
|
||
|
|
- - -If (or --incremental --fail) can be used from udev to
|
||
|
|
- fail and remove from all arrays a device which has been
|
||
|
|
- unplugged from the system. i.e. hot-unplug-support.
|
||
|
|
- - "mdadm /dev/mdX --re-add missing" will look for any device
|
||
|
|
- that looks like it should be a member of /dev/mdX but isn't
|
||
|
|
- and will automatically --re-add it
|
||
|
|
- - Now compile with -Wextra to get extra warnings.
|
||
|
|
- - Lots of minor bug fixes, documentation improvements, etcc
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.1.2
|
||
|
|
- - The default metadata has change again (sorry about that).
|
||
|
|
- It is now v1.2 and will hopefully stay that way. It turned
|
||
|
|
- out there with boot-block issues with v1.1 which make it
|
||
|
|
- unsuitable for a default, though in many cases it is still
|
||
|
|
- suitable to use.
|
||
|
|
- - Stopping a container is not permitted when members are still
|
||
|
|
- active
|
||
|
|
- - Add 'homehost' to the valid words for the "AUTO" config file
|
||
|
|
- line. When followed by "-all", this causes mdadm to
|
||
|
|
- auto-assemble any array belonging to this host, but not
|
||
|
|
- auto-assemble anything else.
|
||
|
|
- - Fix some bugs with "--grow --chunksize=" for changing chunksize.
|
||
|
|
- - VAR_RUN can be easily changed at compile time just like ALT_RUN.
|
||
|
|
- This gives distros more flexability in how to manage the
|
||
|
|
- pid and sock files that mdmon needs.
|
||
|
|
- - Various mdmon fixes
|
||
|
|
- - Alway make bitmap 4K-aligned if at all possible.
|
||
|
|
- - If mdadm.conf lists arrays which have inter-dependencies,
|
||
|
|
- the previously had to be listed in the "right" order. Now
|
||
|
|
- any order should work.
|
||
|
|
- - Fix --force assembly of v1.x arrays which are in the process
|
||
|
|
- of recovering.
|
||
|
|
- - Add section on 'scrubbing' to 'md' man page.
|
||
|
|
- - Various command-line-option parsing improvements.
|
||
|
|
- - ... and lots of other bug fixes.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.1.1
|
||
|
|
- - Multiple fixes for new --grow levels including fixes for
|
||
|
|
- serious data corruption problems.
|
||
|
|
- - Change default metadata to v1.1
|
||
|
|
- - Change default chunk size to 512K
|
||
|
|
- - Change default bitmap chunk size to 64Meg
|
||
|
|
- - When --re-add is used, don't fall back to
|
||
|
|
- --add if --re-add fails as this can destroy data.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.1
|
||
|
|
- - Support --grow to change the layout of RAID4/5/6
|
||
|
|
- - Support --grow to change the chunksize of raid 4/5/6
|
||
|
|
- - Support --grow to change level from RAID1 -> RAID5 -> RAID6 and
|
||
|
|
- back.
|
||
|
|
- - Support --grow to reduce the number of devices in RAID4/5/6.
|
||
|
|
- - Support restart of these grow options which assembling an array
|
||
|
|
- which is partially grown.
|
||
|
|
- - Assorted tests of this code, and of different RAID6 layouts.
|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.0.3
|
||
|
|
- - Improvements for creating arrays giving just a name, like 'foo',
|
||
|
|
- rather than the full '/dev/md/foo'.
|
||
|
|
- - Improvements for assembling member arrays of containers.
|
||
|
|
- - Improvements to test suite

|
|
- by "mdadm --monitor"
|
||
|
|
- - Improvements to mdmon 'hand-over' from initrd to final root.
|
||
|
|
- - Handle merging of devices that have left an IMSM array and are
|
||
|
|
- being re-incorporated.
|
||
|
|
- - Add missing space in "--detail --brief" output.
|
||
|
|
-
|
||
|

|
- early boot.
|
||
|

|
||
|
|
-
|
||
|
|
-Changes Prior to release 3.0
|
||
|
|
- - Support for externally managed metadata, specifically DDF and IMSM.
|
||
|
|
- - Depend on udev to create entries in /dev, rather than creating them
|
||
|
|
- ourselves.
|
||
|
|
- - remove --auto-update-home-hosts
|
||
|
|
- - new config file line "auto"
