By default pvmove allocates extents on pvs OTHER than the one they are
coming from. If you want to move extents around on the same PV, IIRC,
you have to pass --alloc anywhere, and explicitly specify destination
extents.
At any rate, this isn't really a bug. It is by design that you can not
reduce a pv below its last allocated extent. If extent fragmentation is
a problem, lvm currently does not support auto defragmentation. So this
is really a feature request.
