Title:
  Upgrade vom 10.04 LTS Server to 12.04 LTS Server breaks grub

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  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:

  ...
