I have been trying to setup a mirror across 2 servers with gluster (3.2.5) on ubuntu 12.04 for a day or so now and can't figure out what I am doing wrong.

I have a openvpn tunnel between the two vps

Currently there are no iptables rules for the openvpn interfaces

I setup an initial volume using the following command:
gluster volume create vmail replica 2 transport tcp gserver1:/var/export/vmail gserver2:/var/export/vmail
Gluster reports the volume is created successfully; I then start it and it starts and for volume info shows the local and remote blocks.

I mounted using this command:
mount.glusterfs gserver1:/vmail /var/vmail
I get this error:
~# df -h
df: `/var/vmail': Transport endpoint is not connected
I see the following errors in the brick log file which I have googled but to be honest can't find anything that looks very useful:
I [glusterfsd.c:1493:main] 0-/usr/sbin/glusterfsd: Started running /usr/sbin/glusterfsd version 3.2.5

Can someone help me to fix this? All I want is 2 way replication (HA) across these 2 servers.
