Hi Guys,
I'm looking at a server with a bunch of disks that had a raid 5 with two
spares, however, one of the spares failed, the system then started
rebuilding on the other and it crashed during the rebuild.
I'm now left in the following situation :
for a in a b c d e f g h i; do mdadm --examine --scan /dev/sd${a}; done
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:5feed4c5:31c51eb2
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:5feed4c5:31c51eb2
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:5feed4c5:31c51eb2
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:5feed4c5:31c51eb2
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:5feed4c5:31c51eb2
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:8d12a2d2:3188faf0
spares=1
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:8d12a2d2:3188faf0
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:8d12a2d2:3188faf0
spares=1
ARRAY /dev/md0 level=raid5 num-devices=7 UUID=e1e75e8b:f9f387cd:8d12a2d2:3188faf0
The system complains because of the different uuids, and refuses to
recreate the array.
Is it basically stuffed, or is there something I can do to recover the
2TB filesystem that's on there ?
Cheers,
Eamonn
