I've got the following error when I try to setup silo :

livecd log # silo
/etc/silo.conf appears to be valid
Fatal error: Could not open RAID device



Have you got any ideas ?
Thanx by advance,

Seb.

You seem to have partitioned your disk in a very odd way, you should have created the partitions under /dev/sda & /dev/sdb, instead you are using subpartitions (/dev/sda1p1 etc)... was that intentional?
