Depends. If the drive is really faulty, you want to replace it. However it is was a transient error you need to remove and then re-add the devices: mdadm /dev/md1 -r /dev/ide/host2/bus0/target0/lun0/part5 mdadm /dev/md4 -r /dev/ide/host2/bus0/target0/lun0/part7 mdadm /dev/md1 -a /dev/ide/host2/bus0/target0/lun0/part5 mdadm /dev/md4 -a /dev/ide/host2/bus0/target0/lun0/part7 > > Concerning md5 (raid 5), 3 drives are used.
