As such the snapshot device has identical LVM2 metadata as the origin device. You need to generate new PV, VG, LV UUIDs, modify the metadata and then restore that modified metadata to the snapshot device (via vgcfgbackup, vgcfgrestore). EVMS has a decent random lvm2 UUID generator function that can be pulled out and made to run standalone.
