What I did was get everything running in RAID mode
except for /boot. I compeletly RAIDed the root, swap,
and other partitions except for /boot. I rebooted
and had everything but /boot running in RAID mode with
the 'failed-disk' changed to 'raid-disk' and synced
with the 'raidhotadd' command. This includes updating
/etc/fstab and lilo.conf. In lilo.conf you need
to point 'root=' to the RAID device and run lilo
to update stuff, but don't change the 'boot=' field
yet. You need to do the fstab and lilo update before
Once this was all working, I then did the RAID conversion
on /boot. The steps I took for /boot where:
1) Shutdown 0 (to get to single user mode).
2) Copy /boot to /dev/md0 (I created md0 when I created
the other RAID devices).
3) Umount old /boot
4) Mount /dev/md0 as /boot
5) Edit /etc/fstab to point /boot at the RAID device.
6) Edit lilo.conf to point /boot at the RAID devivce,
add the 'raid-extra-boot' line with BOTH
7) Run lilo -vt (testing) and see if everything
8) Then I ran lilo -v .
10) Once the system was up and running I finished
the RAID conversion of /boot.
10a) Once the RAID conversion of /boot was done
I ran lilo -v again. I don't think this is needed,
but I did it anyways.
This worked for the first time for me. Unlike
what is documented in the HOWTO for booting
from a RAID, which created an unbootable system :-( .
For the above to work you need the latest lilo version
(22.1) so check that before starting down this road.
