I have set up a system as follows: /boot raid 1 200mb 4 drives no spares (I guess this makes 4 copies of the data?) 2 250mb raid1 arrays over the 4 drives (2 drives each ) for swap rest of space in 2 raid 1 arrays lvm on top of the 2 raid1 arrays / 10gb on lvm /data 50gb on lvm /backup 250gb on lvm rest of space left free to allow for resizing and adding of partitions with lvm I will pull out a drive tommorow and see how resilient this is. Does this sound like a good solution? Russ
