No, the amount of data is still the same and the files are identical.
I'm just running another rebalance now, with 3.4.2 packages that I've
compiled myself on our build server. So I'll see if that's any
different.

Also since I'm in it. I'm just looking on the 'rebalance status' and I
would expect it to be the same on all the bricks (servers). However the
output is quite different.

On the 'primary' server under 'Node' are all 4 servers: localhost and
3 hostnames. On its replica there are: 3 primaries + one hostname
randomly changing (two hostnames from replica 2)

gluster08 - primary
        Node
   ---------
   localhost
gluster07.uat
gluster01.uat
gluster02.uat


gluster07 - replica with 08
        Node
   ---------
   localhost
gluster08.uat
gluster08.uat
gluster08.uat
gluster02.uat


On the second replica there are: 4 localhosts + one hostname randomly
changing (two hostnames from replica 1 + its own replica hostname)

gluster01
        Node
   ---------
   localhost
   localhost
   localhost
   localhost
gluster08.uat


gluster02 - replica with 01
        Node
   ---------
   localhost
   localhost
   localhost
   localhost
gluster01.uat


Is this right?
