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.
Mirroring swap isn't a bad idea also because your running system would break if a disk crashes with swapped data on it.
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.
SUSE normally starts mdadm and notifies you about disk breakage. For extended supervision Nagios is even better. That's the whole reason for a RAID system, to be able to repair disk failures in a scheduled and organized way without crashing a running system. Not mirroring the swap partition counters that advantage and is bad advice, IMNSHO.
