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...)
Regards,
Oliver
