Oh balls, that's the PV UUID, not the VG UUID. Back to square one.

You need to either temporarily pull sda2 out, and boot off a rescue disk to 
rename it, or vice versa. Or find out the UUID of the volume ... if you're 
lucky, "vgdisplay --verbose" *might* pick up the duplicate and show you the 
UUID for it.
