[Bug 999076] [NEW] Upgrade vom 10.04 LTS Server to 12.04 LTS Server breaks grub

[Fabian Zeindl]

Public bug reported:

I tried to upgrade a server, and i was left with a broken grub2. I think
it has to do something with LVM/RAID.

My setup: /root lies on LVM which is on a Raid5. There's not separate
boot partition.

When i reinstall grub2 from the command-line i get the following errors:
