<div dir="ltr">I am in the process of upgrading my cluster while at the same time
moving to gluster. My engine is version 3.3.1 and I have a NFS cluster running
in 3.1 compatibility mode that I am moving to a 3.3 GlusterFS cluster.
Host3 runs the engine and is on the NFS cluster while host2 is running a
single brick gluster volume and a few vms on the Gluster cluster.
Host1 is the machine I am trying to move from the NFS cluster to the
Gluster cluster. Host1 is upgraded to the latest vdsm/gluster/etc (done
via the host re-install option in the UI while in maintenance mode). I attempt to
change the datacenter/cluster on the host edit page and after I press OK I get the following
error in the UI: "Error while executing action ChangeVDSCluster: Network
error during communication with the Host." I have checked all IPs and
DNS resolutions and even went so far to disable iptables on all of the
hosts to make sure I don't have any firewall issues. Host1/2 is running
latest centos 6.5 and Host3 is slightly behind on centos 6.4.<br>

<br></div>While attempting to make the change I have tailed the engine.log and it is in the following pastebin <a href="http://pastebin.com/1yaK4vYt" target="_blank">http://pastebin.com/1yaK4vYt</a>.<br><br>Any help would be great. I just need a direction to look in.<br>
