Hi,

    I think in the above patch they are just   hiding the the query for 
mount_options but i think all the code is still present and you should 
not loose mount options during additional host deployment. For more info 
you can refer [1].

     You can set this option manually on all nodes by editing 
/etc/ovirt-hosted-engine/hosted-engine.conf. Following steps will help 
you to achieve this.

1) Move each host to maintenance, edit the file 
'/etc/ovirt-hosted-engine/hosted-engine.conf'.
2) set mnt_options = backup-volfile-servers=<gluster_ip2>:<gluster_ip3>
3) restart the services 'systemctl restart ovirt-ha-agent' ; 'systemctl 
restart ovirt-ha-broker'
4) Activate the node.

Repeat the above steps for all the nodes in the cluster.
