Den korte udgave er:
1) lav et raid ved siden af uden den existerende disk, evt. bare et
"failed" raid1 mirror med kun en disk.
2) mount det raid som /mnt
3) find / -xdev | cpio -pm /mnt
4) ret i fstab så root er det nye raid
5) ret i grub/lilo.conf

6) Lav ny initrd med RAID modulerne.

Og måske:

0) Test det på gammelt hardware man har liggende
til overs.

hvad gør/er 3) find / -xdev | cpio -pm /mnt ?

Så er det lykes mig at få booted det nye degraded raid1
med denne grub på hd0:
title		Ubuntu 8.04.3 LTS, kernel 2.6.24-26-server-RAID0
root		(hd0,0)
kernel		/boot/vmlinuz-2.6.24-26-server root=/dev/md0 ro quiet splash
initrd		/boot/initrd.img-2.6.24-26-server
quiet

Så er bare spørgsmålet om jeg får indraget dev/sda1 i raidet.

Leif
