At least you learned your lesson on a test box. Here what I'd suggest. Turn off the swap. (Only because its a test box. On the production server you'd want to create a new swap first.) #swapoff /dev/md2 Umount the array #umount /dev/md2 Then stop it mdadm --stop /dev/md0 Create new swap now I don't raid swap. As stated in the Software Raid How-To ||"There's no reason to use RAID for swap performance reasons. The kernel itself can stripe swapping on several devices, if you just give them the same priority in the |/etc/fstab| file." Assuming you made your raid 0 over all four drives. (never done this post install but I believe it would go like this) go into fdisk and change partition type to 82 mkswap /dev/sda2 mkswap /dev/sdb2 mkswap /dev/sdc2 mkswap /dev/sdd2 Edit fstab file and give them the same priority swapon -p 1 /dev/sda2 swapon -p 1 /dev/sdb2 swapon -p 1 /dev/sdc2 swapon -p 1 /dev/sdd2 and all should be good.
