I've managed to get myself into a little problem.
Since power hits were taking out the /boot partition, I decided to split
/boot out of root. Working from my emergency partition, I copied all
files from /root, re-partitioned what had been /root into room for /boot
and /root, and then created the drives. This left me with /dev/md/boot,
/dev/md/root, and /dev/md/base (everything else).
I modified mdadm.conf on the emergency partition, used update-initramfs
to make certain that the new md drives would be recognized, and
rebooted. This worked as expected.
I then mounted all the entire new file system on a mount point, copied
the mdadm.conf to that point, did a chroot to that point, and did an
update-initramfs so that the non-emergency partition would have the
updated mdadm.conf. This worked -- but with complaints about missing the
file /proc/modules (which is not present under chroot). If I use the -v
option I can see the raid456, raid1, etc. modules loading.
I modified menu.lst to make certain that boot=/dev/md/boot, ran grub
(thanks, Robin!) successfully.
Problem: on reboot, the I get an error message:
root (hd0,1) (Moshe comment: as expected)
Filesystem type is xfs, partition type 0xfd (Moshe comment: as expected)
kernel /boot/vmliuz-etc.-amd64 root=/dev/md/boot ro
Error 15: File not found
Did I miss something? I'm pretty certain this is the procedure I used
before. The XFS module is being loaded by update-initramfs, so unless
there's a reason that I can't boot md from a boot partition with the
XFS file system, then I don't understand what the problem is.
Comments welcome -- I'm wedged!
