If you want the system to survive losing a disk (i.e. it stays up until you shut it down to swap the disk (if you don't have hot swap)), you must RAID all partitions, including swap. In a ks.cfg, it looks something like this:
The reason I don't softraid1 my swaps is that the default behavior is striping a-la-raid0 if you have multiple swaps. At least that's my understanding of it.
You guys bring up a good point in case of drive failure. I never tested it. Do you guys know what happens if the swaps are not softraid1? Does the kernel panic or something of the like? Or does it survive and just operate on less swapspace?
Well it dies horribly ... out and out locked up for me using RH 7.3 when a drive that is using un-mirrored swap failed. After that I decided mirrored swap was a good thing.
