Well thanks Mike and Jon, I think I'm going to simplify my approach: * Forget RAID * Partition for /boot and swap on SCSI Drive without LVM * VG for Data (/usr, /var, /svr) using all 3 80Gb IDE drives * VG for remaining System on SCSI Great I now also need to look into a backup solution for 240Gb! Have I missed anything? Ta DM
