Description of problem: Following documentation and I get this un-expected qualification that according to docs isnt what I expect. =========== [root@glustep1 ~]# gluster volume create gv0 replica 2 glusterp1:/bricks/brick1/gv0 glusterp2:/bricks/brick1/gv0 glusterp3:/bricks/brick1/gv0 glusterp4:/bricks/brick1/gv0 Replica 2 volumes are prone to split-brain. Use Arbiter or Replica 3 to avoid this. See: http://docs.gluster.org/en/latest/Administrator%20Guide/Split%20brain%20and%20ways%20to%20deal%20with%20it/. Do you still want to continue?
