I don't know what I'm doing with LVM so can't help, but I can
say that you don't want to run swap on raid5.  Probably you
want to run it on raid0, perhaps raid 1 if you've hot-swappable
drives and want to maximize uptime.

Thanks for your recommendation regarding RAID 5 on swap partitions. There's not so much swapping on my machine, so I didn't really notice the drawbacks resulting from the CPU XORing for the raid 5 algarithm. My idea really was to avoid the machine going down in case of a disk crash in the raid array. But you are right, I will change the swap partition to RAID 1 (...if I ever will get back my data from my LVM partition...)
