This type of message usually implies that the machine can see a
storage device that is no longer part of a volume group, but has not
been wiped (pvremove). This can happen for any number of reasons.
The admin may have repartitioned something and forgot to wipe the
PVs... a disk failed and came back... new disks were added that had
LVM metadata on them... etc.
Certainly try the suggestion about 'partprobe' and restarting
clvmd... If that works, great. Otherwise, you will have to find the
partition with the stray PV metadata on it - perhaps best done by
reconciling 'cat /proc/partitions' and 'pvs'.
