[linux-lvm] lvremove or vgextend: metadata too large for circular buffer

We're hitting the "metadata too large for circular buffer" problem. Last
time this occurred, I was able to clear out a little space by removing
some unused volumes, and then make more space by selective use of pvmove
to defragment. This worked well.
However, that time I didn't get the error from lvremove. This time, that
is occurring. So I don't seem to be able to make any space.
Once I execute lvremove on a volume, the "LV Status" becomes "NOT
available". The command 'lvdisplay -m' still shows the segments, however.
How can I resolve this? Trashing the entire VG is not something I can
afford.
I created new PVs with larger allocations of space for metadata, but I
cannot even add these to the VG. The vgextend command also fails with
"metadata too large for circular buffer".
