This relates to the granularity problem I mentioned earlier. As long as we're not splitting bricks into smaller units, our flexibility to do things like add a single disk is very limited and the performance impact of rebalance is large. Automatically triggering rebalance would avoid a manual step, but it would just make the pain immediate instead of prolonged. ;) When we start splitting bricks into tiles or bricklets or whatever we want to call them, a lot of what you talk about will become more feasible. _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
