Some LVM commands falsely report missing PVs even though the corresponding disks are present, have correct metadata and they are not marked with the "MISSING" flag.

Issue

• Some types of LVM commands report one or more PVs as missing. As an example, lvs reports the missing PVs, while pvs does not.

• These PVs exist on the system, they are not flagged as MISSING in LVM metadata and their on-disk metadata is correct. A sample of an lvs command reporting the missing PVs is:

  # lvs
