You could avoid that by not using RAID for swap. Instead, use four separate swap partitions, one on each drive. As long as they all have the same priority, the kernel will share swap duties between them equally. There's no real benefit to using RAID for swap, unless you are limited on RAM and use swap a lot, when RAID0 may help. -- Neil Bothwick Excuse me for butting in, but I'm interrupt-driven.
