Make a mirror (/dev/md0) with 1 drive (/dev/hdb) and one failed device.
mkfs the mirror
mount it on /tmp/mnt
rsync -ax / /tmp/mnt
vi /etc/lilo.conf (not the mirror version)
modify lilo.conf to point the "root=" to /dev/md0, don't touch "boot="
vi /tmp/mnt/etc/fstab (not the original version)
set up root to point to /dev/md0
make sure you have a bootable CD (knoppix, debian install, etc) for
recover if it hits the fan
execute lilo
reboot, hopefully off the mirror
If all goes well and sync's up add the original hda into the mirrorf
and update your lilo.conf per the man page:
root=/dev/md0
boot=/dev/md0
raid-extra-boot=/dev/hda,/dev/hdb
If it fails, boot off the recovery cd/floppy and try to mount /dev/md0
(might have to start raid manually) to see if it's functional. If not
mount up /dev/hda1 and restore to booting off that.
Don't forget any additional file systems.
