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 ?
