Subject: [PATCH 090/157] mdadm/tests: 07autoassemble
|
||
|
|
|
||
|
|
This test is used to test stacked array auto assemble.
|
||
|
|
|
||
|
|
There are two different cases depends on if array is foreign or not.
|
||
|
|
If the array is foreign, the stacked array (md0 is on md1 and md2)
|
||
|
|
can't be assembled with name md0. Because udev rule will run when md1
|
||
|
|
and md2 are assembled and mdadm -I doesn't specify homehost. So it
|
||
|
|
will treat stacked array (md0) as foreign array and choose md127 as
|
||
|
|
the device node name (/dev/md127)
|
||
|
|
|
||
|
|
Add the case that stacked array is local.

||
