Just adding more info on the on the raid0 and raid1 and grub. I have just remembered where I got that info from. RHEL-4 will only let you select raid0 or raid1 for the /boot partition, or for / if /boot is not a separate partition during install. I suspect this is a RHEL issue and not a grub issue, but truly, I don't know. I just did not want to be putting out bad info, so I thought I would expand on why I thought only raid0 and raid1 would work for grub.Chris Willard wrote:Hi All, I have a pc with 3x40GB IDE drives. I have 2 RAID 5 devices setup- /dev/md0 = 3 x 38GB as / /dev/md1 = 3 x 2GB as SWAP Debian base installs OK but when I get to the Grub installation I get a "Fatal Error" message. I am telling Grub to install on /dev/md0 but it won't install. Any tips would be appreciated. Regards, ChrisChris,AFAIK, grub can only be set up on a raid0 or a raid1 device. So far, I can not document this, but I seem to recall that fact. As others said, you need to install grub on REAL devices. You can see www.damtek.com for a (I hope rather thorough) walk through on how to set up grub on a raid.
Since I can't find any documentation on the limits of raid and grub, I suspect you can run raid5. Anybody willing to confirm this for me?
