Even on my 3+ disk RAID level 5 systems, I make /boot a RAID 1 mirrored across all drives as /boot can not be RAID5. I mirror /boot and <swap> because if either is lost, the system dies. :) Imagine if something was in swap, then swap vanished, and then the system tried to retrieve what was in swap... Not so good. :P The biggest concern is that, on /boot, you need to ensure that grub has been setup on all drive's MBR. The grub shell allows you to ensure that. -- Digimer E-Mail: digimer at alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org
