If you're not familiar with mdadm I highly recommend that you and anyone else running md devices emerge this tool. The tool is pretty easy to use so I won't go into any details on this list. But with it you should be able to inspect and rebuild your md devices. It has saved me a couple of times with my RAID5 md devices. -- David Miller -- [email protected] mailing list
