Public bug reported:
Binary package hint: grub
I've had this problem for quite a while in Ubuntu but hadn't gotten
around to filing a bug report until now. I've got a RAID-1 setup through
mdadm, and every time I upgrade my kernel, update-grub renders my system
unbootable. Here's some output to illustrate a little better.
[EMAIL PROTECTED]:~$ sudo blkid /dev/sdc1
/dev/sdc1: UUID="f218a5dc-17bf-f955-3c6b-183d348f9553" TYPE="mdraid"
[EMAIL PROTECTED]:~$ sudo blkid /dev/sde1
/dev/sde1: UUID="f218a5dc-17bf-f955-3c6b-183d348f9553" TYPE="mdraid"
[EMAIL PROTECTED]:~$ sudo blkid /dev/md0
/dev/md0: UUID="a0d72a95-f804-4881-96de-8de3ceafe674" TYPE="ext3" [/CODE]
So /dev/sdc1 and /dev/sde1 are the two partitions that make up the RAID1
/dev/md0. The problem is that every time I upgrade my kernel, update-grub will
change the lines in /boot/grub/menu.lst that look like: "kernel
/boot/vmlinuz-2.6.24-21-generic root=UUID=a0d72a95-f804-4881-96de-8de3ceafe674
ro quiet splash" to lines that look like: "kernel
/boot/vmlinuz-2.6.24-21-generic root=UUID=f480cccf-8a38-426b-be9f-6af3a5912443
ro quiet splash" This renders my system unbootable as that is not the correct
UUID of /dev/md0, and so the boot fails and I am dumped to a busybox prompt.
Other information that may be useful:
