I have recently updated with 2.2.29.1-avh1~xenial1 ubuntu package on 16.04.

It appears that I have a couple of duplicate GUIDs which fsck can't clear so the machine is looping through doing continuous fsck runs.

Any way to determine what the offending messages are and how to delete or otherwise stop this?
