Comment 91 (https://bugs.launchpad.net/ubuntu/+bug/120375/comments/91) worked for me. I didn't need the extra lvm stuff but it can't hurt.
I was booting from /dev/sdb1, which was the 'failed' drive from /dev/md0. In /etc/fstab, I had /dev/md0 als /, and it shows up as such in 'df'. But /dev/md0 was not really mounted as root; is was /dev/sdb1 altough it *says* it's /dev/md0. This is a bug I think. So I made the changes to the initramfs script, and did update-initramfs -u. BUT THAT HAPPENS ON /dev/sdb1 ! So I had to do this: mount -t ext3 /dev/md0 /mnt cd /mnt chroot . # Change the script in /usr/share/initramfs-tools/scripts/local !!!!! the previous change was on /dev/sdb1 !!! update-initramfs -u exit # from the chroot reboot This took me ten hours or more (linux-haters !) Doesn't anyone think it's *really bad* that all 8.04 installs fail horribly when the root raid-array degrades !? Those machines won't boot at all when that happens ! And it's not going to be fixed in 8.04 ?
