You do take backups, right? :-) For the engine itself, you can use engine-backup. > > How does one recover the cluster setup and not have to start from scratch by > having to rebuild all the nodes? Can the engine just be rebuilt and the ovirt > nodes be imported? You didn't mention your plans re storage. If you put your VMs on well-handled storage, and lose everything but the storage, you can install a new engine, new nodes, and then import the VMs from the existing storage. You will still miss some configuration etc., but should mostly be ok. If you plan to use gluster storage using the same nodes, aka HCI, the same applies, obviously, only that the nodes are your storage, and not an external system. You still have to make sure you handle them properly - backup, DR, etc., depending on your needs and budget. If you do have engine-backup backups, but lost all your storage, engine-backup will not help you. > > This scenario is based on the nodes being built from the ovirt node iso. That's ok, but is not relevant. Main question is the storage. Can be external or local/gluster with either ovirt-node or EL.
