I'm trying to balance Load ( 41.98GB vs 59.4GB vs 74.65GB )

Owns looks ok. They're all 33.33% which is what I want.  It was =
calculated simply by 2^127 / num_nodes.  The only reason the first one =
doesn't start at 0 is that I''ve actually carved the ring planning for 9 =
machines (2 new data centers of 3 machines each).  However only 1 data =
center (DCMTL) is currently up.
