But metadata server aren't mandatory to archive automatic rebalance. Gluster is already able to rebalance and move data around the cluster, and already has the tool to add a single server even in a replica 3. What i'm asking is to automate this feature. Gluster could be able to move bricks around without user intervention. The proper way to add a single server in a replica 3 is the following: # gluster volume replace-brick gv0 server1:/data/brick2 server3:/data/brick2 commit # gluster volume add-brick gv0 server1:/data/brick2 server3:/data/brick1 # gluster volume rebalance gv0 start These step could be automated by gluster, by adding a new command, something like: # gluster volume add-server gv0 server3 # gluster volume rebalance gv0 start Could also be scripted with bash, but integrating this in gluster would be better. Dump question: I don't have a big cluster here with me, can someone post me a "gluster volume info" for a replica 3 with multiple servers and multiple bricks per server ? _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
