I just finished deploying oVirt 4.4.5 onto a 3-node hyperconverged cluster running on Red Hat 8.3 OS.

Over the course of the setup, I noticed that I had to setup the storage for the engine separately from the gluster bricks.

It looks like the engine was installed onto /rhev/data-center/ on the first host, whereas the gluster bricks for all 3 hosts are on /gluster_bricks/.

/rhev/data-center is a mountpoint of the gluster volume which may have its bricks in /gluster_bricks/. You can provide more info on the gluster setup to clarify this. gluster volume info <volume name>

I fear that I may already know the answer to this, but:
Is it possible to make the engine highly available?

Yes, one uses 3 servers to achieve HA for the guest VMs and the engine, as long as the hosts meet the requirements of storage, network and compute.

Also, thinking hypothetically here, what would happen to my VMs that are physically on the first server, if the first server crashed? The engine is what handles the high availability, correct? So what if a VM was running on the first host? There would be nothing to automatically "move" it to one of the remaining healthy hosts.

Or am I misunderstanding something here?
