I see frequents errors in the vdsm log on one of the gluster servers in my gluster cluster. Can anyone suggest a way to troubleshoot this, the host is fine in the ovirt console and gluster functions ok. The Gluster cluster is a replica 2, with 2 hosts. I am trying to add another host to move to replica 3 but having trouble and this error seems to cause any changes to the cluster to fail with unexpected errors in ovirt. -Thanks, Alastair Gluster Server VentOS 6.6: vdsmd: vdsm-4.16.7-1.gitdb83943.el6 gluster: glusterfs-3.6.1-1.el6 ovirt host Fedora 20: hosted ovirt-engine 3.5.0.1-1 Thread-53::DEBUG::2014-11-24
