I found something else peculiar:

on node A:
[root at omadvnfs01a ~]# lvmdiskscan
  /dev/sdc1                  [        4.00 TB] LVM physical volume

on node B:
[root at omadvnfs01b ~]# lvmdiskscan
  /dev/sdh1                  [        3.81 TB] LVM physical volume

Not sure how they could be different sizes.  I don't see any references in
/dev/mapper either.  Shouldn't those be created with the VG?

Thanks!
