Does it help if you reboot the node?

Some people reported that is possible to fix this with vgcfgbackup/vgcfgrestore,
but you should be really careful when doing such things (backup everything
first).

# vgcfgbackup -f lvmbackup.txt pve

edit transaction_id inside lvmbackup.txt

# vgcfgrestore --file lvmbackup.txt --force pve

So it is likely that more than this is damaged (what happened exactly?)...
