The swap should not be on a raid array, as the kernel can handle 
multiple swaps on different drives.

If you put swap on a raid array you will more than likely find it will 
not be used, as I found out.

I have now deleted the array for swap and made it 2 seperate swaps and 
put them in fstab with both
having the same priority.
