[Gluster-users] (3.1.6-1) How should I add extra peers to existing file systems ?

Logs are generally in /var/log/gluster

Since you are playing with it. I would suggest this:

1) run peer detach for all the servers
2) from server 1 ->3 and 3->1 make sure ports are open and iptables
are turned off.
3) remove config files under /etc/glusterd
4) run your tests again.
