[Gluster-users] Rebalance failures

I am messing around with gluster management and I've added a couple bricks
and did a rebalance, first fix-layout and then migrate data.  When I do
this I seem to get a lot of failures:

gluster> volume rebalance MAIL status
                                    Node Rebalanced-files          size

   45069            0      completed

The logs for this show:

All the gluster servers have the same amount of disk space so I'm confused
by the failure.  Is this something to be worried about?
