How can I be sure? How do I check?
This SAN exports another set of 4 LUNs to a different server and they
work just fine.
pvcreate --version
LVM version: 2.00.33 (2005-01-07)
Library version: 1.00.19-ioctl (2004-07-03)
Driver version: 4.4.0
pvcreate on the server that does not work is a little newer, so I wonder
if there was any new code/bug fix(es) since this version that caused a
regression.
