Hyper V 2012 and EMC VNX Thin provisioning

We have an issue with our EMC VNX attached Hyper V 2012 LUNs that are thin provisoned (thru the VNX). This provisioning works fine until you have to expand a LUN or migrate it. Then the LUN size baloons to the real (non-thin) size.

Has anyone else seen this problem? Is there a solution? This is causing us to rethink Hyper V and migrate back towards VM ware. We are currently/50/50 across the platforms with about 150 hosts of each type.
