Since the on-disk structure of JBOD, RAID-0, RAID-3, RAID-5, RAID-0+1, RAID-1+0, RAID-10, etc, etc are all different, you have to wipe the disks. If the OS is on a separate disk from the data (including /home), you won't have to rebuild the server, "just" the data disks. You have a reliable tape drive, and you've tested the reliability of your backups, right? -- ----------------------------------------------------------------- Ron Johnson, Jr. Jefferson, LA USA PGP Key ID 8834C06B "Bureaucracy defends the status quo long past the time when the quo has lost its status."
