[Bug 452350] [NEW] Unknown LVM metadata header

[Mike Hobbs]

Public bug reported:

Binary package hint: grub2

update-grub2 appears to run successfully, but generates a lot of "error:
Unknown LVM metadata header" messages in the process. LVM was created
during install on a clean system (using ubuntu-9.10-beta-
alternate-i386.iso).

$ sudo update-grub2

Here's some extra info that may help:
