Oh no! RAID 5 down...

[-zax-]

Anyone have any experience restoring a SCSI RAID 5 array on FreeBSD?

The server is a Dell Poweredge 2550

Had a major mail server go down that was running 5x 39gb SCSI drives. I believe 2 of the drives are toast, as when the backplane of the server went out, it corrupted data on 2 of the 5 drives. Anyone know how to recover data on a RAID 5 array through FreeBSD? I've done it with RAID 1, but not 5...

Kind of a sitting duck right now.

If anyone has any ideas... LMK.

Thanks in advance.

edit: It is saying that there are "No Containers" when going into the SCSI configuration utility.

if u loose 2 or more drives u loose everything.

Yep, RAID 5 can't withstand 2 disk failures at the same time. Best to consult with a data recovery place and see what they can do if its that important.

Restore for yesturday's backup. You have one right?
If the backplane corrupted the other drives, you probably don't want to try and restore from the drives. Use the most recent known good backup.
