Hello Everyone, Can someone help me to clarify this ? I have a single-node 4.2.8 installation ( only two gluster storage domains - distributed single drive volumes ). Now I just got two identintical servers and I would like to go for a 3 nodes bundle. Is it possible ( after joining the new nodes to the cluster ) to expand the existing volumes across the new nodes and change them to replica 3 arbitrated ? If so, could you share with me what would it be the procedure ? Thank you very much ! Leo
