[linux-lvm] metadata too large for circular buffer - any way to increase PV metadatasize?

I'm getting the dreaded "metadata too large for circular buffer" message
trying to create a new LV in a volume group of a few hundred other LVs.
As I understand, this is because the PVs don't have enough space for the
metadata. This size can be set to a larger value when pvcreating with
--metadatasize but I have obviously missed that boat :)
Is there a way to increase this with live PVs, rather than shifting all
the data off them and recreating and shifting back on?
I have a multinode RedHat Cluster with CLVMD and two PVs. I can add
additional PVs if that helps (though as I understand *every* PV needs
enough metadata space).
Thanks in advance!
