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.
While attempting to make the change I have tailed the engine.log and it is
in the following pastebin
http://pastebin.com/1yaK4vYt.
Any help would be great. I just need a direction to look in.
