<p><font face="Helvetica, Arial, sans-serif">I'm using the DNS Balancing
gluster hostname for years now, not only with ovirt. No software
so far had a problem. And setting the hostname to only one Host
of course breaks one advantage of a distributed/replicated
Cluster File-System like loadbalancing the connections to the
storage and/or failover if one host is missing. In earlier ovirt
it wasn't possible to specify something like "backupvolfile-server"
for a High-Available hosted-engine rollout (which I use).</font></p>
<p><font face="Helvetica, Arial, sans-serif">I already used live
migration in such a setup. This was done with pure libvirt
setup/virsh and later using OpenNebula.</font></p>

I replayed migration (10:38:02 local time) and recorded
vdsm.log of source and destination as attached. I can't
find anything in the gluster logs that shows an error.
One information: my FQDN <a
href="http://glusterfs.rxmgmt.databay.de"
target="_blank" moz-do-not-send="true">glusterfs.rxmgmt.databay.de</a>
points to all the gluster hosts:<br>

I double checked all gluster hosts. They all are
configured the same regarding "<tt>option
rpc-auth-allow-insecure on</tt>" No iptables rules on
the host.<br>

<div>Do you use '<a
href="http://glusterfs.rxmgmt.databay.de"
moz-do-not-send="true">glusterfs.rxmgmt.databay.de</a>"
as a storage domain host name? I'm not a gluster guru, but
i'm afraid that some internal gluster client code may go
crazy, when it receives different address or several ip
addresses every time. Is it possible to try with separate
names? You can create a storage domain using
172.16.252.121 for example and it should work bypassing
your DNS. If it is possible to make that, could you please
do that and retry live migration?</div>
