No.  LVMs still get passed 512-byte indexed requests.  A LVM exports a
block device, and that block device is just as much subject to the 2TB
limit as the physical block devices underneath it are.  The fact that
the LVM device is a virtual device, not a physical one, does not make
a difference, sadly.
