[linux-lvm] pvscan is not recognizing physical volumes

[Anthony Nelson]

We have a system that pvscan is not recognizing the physical volumes 
which is preventing it from cleanly booting. The linux kernel images are 
on the lvm partitions. The partitions correctly show as LVM partitions 
when doing an fdisk -l, but the pvscan says "No matching physical volume 
found".

I was suggested to try doing a vgscan -vvvv and the only thing that 
looked odd was a message saying "No label detected" prior to closing the 
disk.

Some of the steps I have gone through and documentation of this issue 
can be found on the serverfault question I opened yesterday. You can see 
that here:

Thanks,
Anthony
