Isn't mirroring a swap partition a bad idea, or at the least wasteful?
Mirroring is not too bad for swap. When the system needs to read swap the raid drivers will read from which ever disk is not busy, so it might be faster than non-raid, but only slightly so.
A swap on raid5 is quite a bit slower.
Mirroring swap isn't a bad idea also because your running system would break if a disk crashes with swapped data on it.
as mentioned by others in this thread, I put seperate swaps one on each disk, and raid the rest. This means that the machine crashes when a disk breaks. The system then works after a reboot. In this form I Immedeatetly know when a disk breaks at one of my SOHO clients. I find that to be a major plus. Jerry
