If you removed a disk from a server and forgot to cleanly remove the configuration you may experience something similar.

Below shows what happens with lvremove:

# lvremove --force --verbose /dev/vg02/u01
  WARNING: Device for PV ore6TE-2ues-rc5q-mkCN-hEHE-C4Av-paaxEH not found or rejected by a filter.
    There are 1 physical volumes missing.
    Archiving volume group "vg02" metadata (seqno 2).
    Releasing logical volume "u01"
  Aborting vg_write: No metadata areas to write to!

Some people seem to have success with vgreduce commands but I ended up making a fake device and extending the VG in order to cleanup the LV.
