Do you realize you effectively have 10 partitions, that we know of, on a single disk? What's the advantage of sda2 and sda3 being separate instead of in a single VG? You're basically increasing your overall system latency by having multiple PV's on a single spindle. In any case, this is the domain of a different application, not an OS installer. How does having two PVs on the same spindle increase latency? It certainly doesn't decrease it but it shouldn't make a difference whether you make two writes to a single PV or two different PVs in this case as these writes end up on the same spindle either way.
