Hi,
I'm running 4 IDE disks in my home server using software raid with
the following partition layout:
hd[abcd]1 /boot (RAID 1)
hd[abcd]2 swap (RAID 5)
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...)
Regards,
Oliver
