Hello,

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).

As far as i know, backup-volfile-servers is a recommended way to keep you filesystem mountable in case of server failure. While fs is mounted, gluster will automatically provide failover. And you definitely can specify backup-volfile-servers in the storage domain configuration.

I already used live migration in such a setup. This was done with pure libvirt setup/virsh and later using OpenNebula.

Yes, but it was based on a accessing gluster volume as a mount filesystem, not directly... And i would like to exclude that from list of possible causes.
