Take a look at the mdutils package. You can do mirroring (RAID 1), but you'll have to re-partition your disks. I doubt it can continue to run during a hardware failure, though, and it's a pain in the butt to boot from a Linux md (RAID) device. Newer kernels offer RAID 5, which may be a better solution. I think you need three or more disks. Patches are probably available for 2.0.x kernels. For this, look at the raidtools package. Jeff -- Unsubscribe? mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
