[ovirt-users] How to create a backup in event of hardware failure of a single hosted engine?

Hello everyone, Currently we have a single bare metal that hosts oVirt and glusterFS which later on to be converted to a 3 nodes for HCI, currently another bare metal is coming this week and was planning to initially create it as a backup. is it possible to deploy a new hosted engine then create a gluster volume for 1st one as a backup domain then attach it to the new one if hardware failure occurred, or there is another kind of setup that can be done?
