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

[Fabian Zeindl]

Will this remove the "superfluous RAID member" warnings? Because they
are the only ones left.

I'm asking because i'm remotely logged into the machine and can't stop
the RAID to zero the superblock

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

Status in GRand Unified Bootloader:
  Unknown
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:

  ...
