Lost mdadm array after a power cut
While I was at work my house got hit with a power cut, and as a result my server went down. When I booted it back up, debian threw an error that it could not scan the /dev/md0 array.
Closer inspection revealed this was because /dev/md0 no longer exists!
If I look at the contents of /dev I see the individual hard drives (sdb, sdc, sdd, sde, sdf), and a folder md, which is empty.
sudo mdadm -Es gives:
ARRAY /dev/md/0 metadata=1.2 UUID=c437742c:ace165ec:363f227e:caba18a5 name=leonard:0 spares=1 ARRAY /dev/md/0 metadata=1.2 UUID=c437742c:ace165ec:363f227e:caba18a5 name=leonard:0
cat /proc/mdstat gives:
Personalities : [raid6] [raid5] [raid4] unused devices: <none>
I am running Debian squeeze, mdadm is v3.1.4. Any help would be greatly appreciated.
