This doesn't look like something you can do with the volume group active
(with cluster lvm anyway):

[root@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?

Thanks,

John.
