I was thinking to have at /etc/hosts sth like below: <br><br></div>10.100.100.1 nfsmount<br></div>10.100.100.2 nfsmount<br></div>10.100.100.3 nfsmount<br><br></div>then use nfsmount as the server name when adding this domain through ovirt GUI. <br></div>Are there any other more elegant solutions? What do you do for such cases?<br></div>Note: gluster has the back-vol-file option which provides a lean way to have redundancy on the mount point and I am using this when mounting with glusterfs. <br><br></div>Thanx<br></div>
