Try...</blockquote><div> man mdadm This will give you idea of how to manage the array. In such cases where one of the drive of RAID1 array goes bad just giving a command to remove drive from array and then adding it back and giving it time to re-build is sufficient. Unless the drive has physically gone bad there shoud not be a problem and after few minutes (depending on data size) the array will report ok. Note that you have to do this to each raid device ..md1,md2,md3..individually. Raid devices start numbering from 0 and hard disk partitions from 1 ...so typically md0 will have components hda1 and hdb1 The command, in sequence, that I have used are: </div>mdadm /dev/md0 -r /dev/hdb1 mdadm -D /dev/md0 mdadm /dev/md0 -a /dev/hdb1 mdadm -D /dev/md0 Repeat fro all degraded arrays.Again read man pages and make sure you have backup.
