I think clvm can do what you want if you perform LVM commands by hand.
But, with HA cluster manager (pacemaker) you cannot
do it with the current resource agents (clvm + LVM)  , because
they do failover at a VG basis.
We are currently working on new resource agents  for lvmlockd .
The new agents can do activation on LV basis, but I won't
recommend doing that if there's no strong reason. It makes things much
