I Upgraded to Ubuntu12.10, and when grub ran through the upgrade it gave me these errors:
root@secure:/usr/share/grub# update-grub
error: unknown LVM metadata header.
error: unknown LVM metadata header.
Generating grub.cfg ...
error: unknown LVM metadata header.

I haven't rebooted yet, scared that if I do, the pc won't boot correctly.. how do I fix this? Here is a copy of logs that'll be helpful, to see whats going on.. http://pastie.org/4389403
