unused devices:

md0 is /boot, md1 is /, md2 is an LVM2 PV:
PV Name /dev/md2
PV Size 370.59 GB / not usable 0

3*200GB IDE disks, all on a separate IDE controller (main board got a HTP RAID controller, which I disabled so it behaves like a “normal” IDE controller)

Pretty cool stuff to work with :-) And the software RAID is incredibly fast, without using the CPU too much, even on fairly high IO.
