I'll have to look into that. You should be able to use create successfully. If the original order was b2,c2,a2, which is what the --examine suggests, and you want to not use b2, then mdadm --create /dev/md1 -l5 -c32 -n3 missing /dev/sdc2 /dev/sda2 should work. It will not start a rebuild so you can mount it read-only and if something was wrong, you can "mdadm --stop" and try again with a different arrangement of drives. If b2 and c2 are really the most recent, as it appears, then you might want to use those: mdadm --create /dev/md1 -l5 -c32 -n3 /dev/sdb2 /dev/sdc2 missing Again, this wont do a resync and as long as you don't touch the bad block on b2, you should be able to access data.
