As posted early having swap on a raid zero is a bad idea . Dan
Yes I wasn't thinking too clearly when I made the swap raid0, well I did think about performance, but not drive failure :(
Thanks everyone for your help, Stephen
I did the same thing when I started out using Linux. 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.
