Grub can't do software RAID...that's an OS thing. Your /boot partition MUST be on a either a hardware RAID or a single drive. You can use a software RAID1 for /boot, but that's only because both drives' content will be identical and you're cheating by only using one of the pair. Just make sure you don't write anything to /boot in grub...the software RAID1 must be functional before any writes occur or you will make the RAID1 unmountable as the drives will diverge in content. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - LOOK OUT!!!
