Thanks John. Now bear with me for a while...
I've got this setup:
/boot on /dev/md1 (/dev/sda1 and /dev/sdb1)
root on /dev/md2 (/dev/sda2 and /dev/sdb2)
I've got a normal single-disk installation on /dev/sdb. I've marked all
the partitions on /dev/sda as "failed-disk" in /etc/raidtab. So the RAID
is running in degraded mode, until I manage to boot into it. Then I'll
change the entries to "raid-disk" and raidhotadd the partitions.
This is fairly standard procedure, I understand; you install a single-disk
system, start RAID arrays which include partitions on the disk with the
system on it as "failed-disk", clone the system into the arrays, make the
RAID system bootable, boot into it, mark the "failed" partitions
as "raid" and raidhotadd them. I have done this successfully a number of
times with kernel 2.2 and the older lilo.
Now to keep my single-disk system bootable, I guess from what you write
that I need to put this in /etc/lilo.conf:
# device with /boot filesystem
# MBR's to which lilo will be installed; omit /dev/sdb
# until the RAID system is bootable
# device with root filesystem
And then, once the RAID system is bootable, install the MBR to /dev/sdb as
# MBR's to which lilo will be installed
Am I getting this right? I wouldn't like to trash the single-disk install
