Hi,
here is what /proc/mdstat gives to me after a crash of the server.
2 drives (one on md1 and one on md4 have de (F).
This means they are faulty.
Should I do :
mdadm /dev/md1 -a /dev/ide/host2/bus0/target0/lun0/part5
mdadm /dev/md4 -a /dev/ide/host2/bus0/target0/lun0/part7
or is there an other way to solve the problem ?
Concerning md5 (raid 5), 3 drives are used. I assume the one marked [3] is not
used. What can it be used for ?
Best regards
Eric
