i really hope this could be automated in newer gluster versions
There is almost no sense to make a replica on the same server so gluster
should automatically move bricks to preserve data consistency when adding

Ceph does this by moving objects around and you don't have to add servers
in a multiple of replica

the rebalance command could be used to rebalance newly added bricks by
preserving replicas in a proper state
