Yes, but can you define RAID devices by UUID or Label? If I have a drive go out, I might unplug it and plug it in again and the drive goes from /dev/sdg to /dev/sdh -- the RAID device won't assemble because it isn't /dev/sdg. > $ cat /proc/mdstat > Personalities : [raid1] > md0 : active raid1 sda3[0] sdb3[1] > 973827010 blocks super 1.2 [2/2] [UU] Those drives are not showing via UUID or label here...
