The latest upstream version of lvm has some improvements to help recover from problems like this. So, you could try building lvm 2.03.05, and running 'vgck --updatemetadata'. Otherwise, the old approach has been to use pvcreate with --restorefile and --uuid, followed by vgcfgrestore. (I'd experiment with that using some test devices if possible.)
