Why are you running swap on a raid device?

You DEFINITELY want to do this, otherwise, when 1 disk dies, so does your

Most systems don't use swap. Servers probably never should.

Most recommendations I've read are NOT to use raid for swap.

Some processes might die, but usually the system survives when swap is
demounted.

You sure about that? Even if you have 64GB of RAM, the kernel developers say you should still use swap when I asked them about it.
