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

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.

  • when you ran your create command what did gluster say? Creation of volume "vmail" has been successful. Please start the volume to access data.

  • I did start the volume. I just did not write that in here. And yes, gluster reported the creation of the volume as successful.

For anyone interested in an update:

  • I have since does some testing on a couple of test virtual box instances.

  • I setup the OpenVPN between the two, same as in the real setup.

  • I setup the gluster volumes in the same way, and it all works.

I tried to replicate the exact steps on the real environment and it does not.

It seems to be a tuning issue on the OpenVZ containers, and I have opened a couple of support tickets with them requesting certain tuning parameters I found on another post.

I will update this thread once I have confirmed whether that tuning does or does not work.
