Well, in the "file this future reference" department the pvcreate
command with uuid specification did work!
Here's what it looked like in this particular case:
pvcreate --uuid "oACqnk-YQTQ-IiGy-F6Pj-UoBB-kUqM-g6Yu3D" --restorefile
/etc/lvm/backup/VolGroup00 /dev/sdb
Worked like a charm. Now the display commands work again!
