Hi,
i have a big problem. A had a sw raid5 array with 6 partition. The array
has been damaged because problems of power connectors. 2 partitions/disks don't work,
because during the time the SATA power connections didn't work.
Some write/read operations where running. Now when i want to
run the array loading the kernel, i get the next message:
raid5: device sdl1 operational as raid disk 0
raid5: device sdj1 operational as raid disk 5
raid5: device sdh1 operational as raid disk 3
raid5: device sdg1 operational as raid disk 2
raid5: not enough operational devices for md0 (2/6 failed)
RAID5 conf printout:
--- rd:6 wd:4 fd:2
disk 0, o:1, dev:sdl1
disk 2, o:1, dev:sdg1
disk 3, o:1, dev:sdh1
disk 5, o:1, dev:sdj1
raid5: failed to run raid set md0
I think, that the dammaged partitions have to be used anyway, to get the
datas back.
I attached the result of "mdadm --examine".
Could somebody help me?
Chris

Are you using raid autostart (in-kernel auto-activating of raid
arrays) or bring it up using mdadm? If the latter, try adding
--run option. If the former, your only choice is to use some
rescue CD or something, and again, to try this same mdadm --run...
Depending on where/how you got to this state, your data may
be just fine.
