Subject: [PATCH 2/2] Make sure LVM config is updated before running pvcreate
Our internal "global" LVM config is set during reset() but we have
test cases that run pvcreate without running reset() first so we
need to make sure to update the global config before running it
because the config string now also controls whether the new LVM
devices file will be used or not.

The existing error message can be confusing for people that don't
know internals of blivet and libblockdev and the information what
is actually broken or not installed on the system is missing
completely. Example for LVM VDO with missing kvdo module:
Before:
device type lvmvdopool requires unavailable_dependencies:
libblockdev lvm plugin (vdo technology)
After:
device type lvmvdopool requires unavailable_dependencies:
libblockdev lvm plugin (vdo technology):
libblockdev plugin lvm is loaded but some required technologies
are not available (BD_LVM_TECH_VDO: Kernel module 'kvdo' not
available)

Subject: [PATCH] Use bigger chunk size for thinpools bigger than ~15.88 TiB
With our default chunk size of 64 KiB we cannot create bigger
thin pools than 15.88 TiB. Unfortunately we need to specify chunk
size to be able to calculate thin metadata properly so we can't
simply leave this to LVM to determine the correct chunk size.

Subject: [PATCH 3/7] Switch LVM devices filter from "reject" to "accept" by
default
We currently use the LVM reject filter to filter out hidden and
ignored devices, this commit changes the behaviour to reject all
devices by default and accept only physical volumes that are not
hidden or ignored. This is preparation for the switch from the
existing lvm.conf based filtering to the new devices file based
filtering introduced in LVM 2.03.12 which allows only listing
"accepted" devices. This allows us to support both the "old" and
"new" style filtering using the same code.

Subject: [PATCH 5/7] Make sure PVs are added/deleted to/from the LVM device
file
We are using the --devices option when running LVM commands which
mean the newly created PV won't be added to the device list by
pvcreate so we need to do that manually.

Subject: [PATCH] iscsi: Replace all log_exception_info calls with log.info
We don't get any useful information from the exception, it's
always the same traceback from a failed DBus call and we only use
these when a called failed because firmware ISCSI is not supported.
The resulting log message also looks like a failure with the
traceback logged and not just as a debug information.

Subject: [PATCH] Do not crash when changing disklabel on disks with active
devices
The _find_active_devices_on_action_disks function originally
prevented from making any changes on disks with active devices
(active LVs, mounted partitions etc.) This was changed in
b72e957d2b23444824316331ae21d1c594371e9c and the check currently
prevents only reformatting the disklabel on such disks which
should be already impossible on disks with an existing partition.
This change for the 3.4 stable branch keeps the current behaviour
where the active devices are teared down when running in installer
mode to avoid potential issues with the installer.

Subject: [PATCH 4/4] Add option to attach a newly created cache pool to
existing LV
Because we do not have action for attaching the cache pool, we
cannot schedule both adding the fast PV to the VG and attaching
the cache pool to existing LV. This hack allows to schedule the
attach to happen after the cache pool is created.

We are using "real" disk names ("sda", "sdb"...) in this test so
we need to avoid reading their real sizes which we do for existing
devices using os.stat. The test can fail if we have a disk with
the same name and small (or zero) size.

Subject: [PATCH 1/8] Fix removing zFCP SCSI devices
Values parsed from /proc/scsi/scsi were not correctly used to assemble
paths to SCSI devices.
For example:
/sys/bus/scsi/devices/0:0:00:00/
was incorrectly accessed instead of:
/sys/bus/scsi/devices/0:0:0:0/
Switch to a more reliable way of listing the available SCSI devices.

NPIV zFCP devices can attach more than one SCSI device, so allow to
delete them all. For non-NPIV devices it means possible slowdown, since

This covers only the basic functionallity needed by Anaconda right
now: populating the config files in /etc/nvme and copying them to
the installed system. The API for the NVMe singleton is based on
the similar modules for iSCSI and FCoE.

This happens when trying to use Blivet on a system with a BIOS
RAID without dmraid installed. Because we don't fully support
BIOS RAIDs using MD the MDBiosRaidDevicePopulator helper fails
to get kwargs for the BIOS RAID "disk" and populate fails.
