<p dir="ltr">i really hope this could be automated in newer gluster versions<br>
There is almost no sense to make a replica on the same server so gluster<br>
should automatically move bricks to preserve data consistency when adding servers.</p>
<p dir="ltr">Ceph does this by moving objects around and you don't have to add servers in a multiple of replica</p>
<p dir="ltr">the rebalance command could be used to rebalance newly added bricks by preserving replicas in a proper state </p>
