Grub needs to be able to load the kernel, so you'd need to keep /boot as normal / raid1 partition (raid1 partitions can be read without problems) Apart from that, as long as the partitions are all type raid autodetect (FD?) the kernel will automatically do everything on boot. I have a hotspare in a 5-disk raid5, it's really neat - when a disk fails there's a 2h window where the raid slows down a bit, then the hotspare has taken over and you can just replace the broken disk. And at ~100Eur for one disk it's a "free" bonus ... Hope that helps, Patrick -- Stand still, and let the rest of the universe move
