>From hints here and on the 'net I though that boot raid was possible with the latest version(s) of the kernel, raidpatches & lilo. However I may have been mistaken. I've attempted to created a RAID-1 device 0x901 comprised of two partitions /dev/sde1 & /dev/sdi1 (will eventually be moved to /dev/sda1 & /dev/sde1 once it's successful, /dev/sda is currently a normal boot disk). I have /dev/sde1 & sdi1 both marked as bootable, and with 0xfd as the partition type to automatically start. This so far went well, I copied over my entire distribution to the new device and updated the fstab. I stopped the raid and then individually did a lilo -r to each side of the mirror. (Lilo v0.20). No problems everything was looking good. Then rebooted w/ /dev/sda1 removed. (FYI, all three of these disks are on their own controllers, and have scsi id of 0 which is marked as a bootable disk in the Mylex's (BT-958's) BIOS) The system didn't even load lilo said it couldn't find a system disk. Hmm. Anyone have any pointers here? Things were going reall good, didn't want to stop here.
