Subject: [PATCH] imsm: monitor: do not finish migration if there are no failed
|
|
disks
|
|
|
|
Transition from "degraded" to "recovery" made in OROM is slightly different
|
|
than the same transision in mdadm. Missing disk is not removed from list of
|
|
raid devices, but just from map. Therefore mdadm should not end migration
|
|
basing on existence of list of missing disks but should rely on count of
|
|
failed disks.
