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

This doesn't look like something you can do with the volume group active
(with cluster lvm anyway):
[root at testnode0 ~]# pvcreate --restorefile san-metadata -u fTLglk-j1C1-02Z7-8k6l-DTAm-2WNj-9ZGT19 --metadatacopies 0 /dev/hdb -ff
Really INITIALIZE physical volume "/dev/hdb" of volume group "san" [y/n]? y
Can't open /dev/hdb exclusively. Mounted filesystem?
Is that right, or am I missing something?
