Subject: [PATCH 177/201] mdadm/Grow: sleep a while after removing disk in
|
|
impose_level
|
|
|
|
It needs to remove disks when reshaping from raid456 to raid0. In
|
|
kernel space it sets MD_RECOVERY_RUNNING. And it will fail to change
|
|
level. So wait sometime to let md thread to clear this flag.
|
|
|
|
This is found by test case 05r6tor0.
