[ovirt-users] Re: Hyperconverged engine high availability?
There may be a bug in the latest installer. Or I might have missed a step somewhere.
I did use the 4.4.5 installer for hyperconverged wizard, yes.
I'm currently in the Engine console right now, and I only see 1 host.
I've navigated to Compute -> Hosts.
That said, when I navigate to Compute -> Clusters -> Default, I see this message:
Some new hosts are detected in the cluster. You can Import them to engine or Detach them
from the cluster.
I clicked on Import to try to import them into the engine.
On the next screen, I see the other two physical hosts.
I verified the Gluster peer address, as well as the front-end Host address, typed in the
root password, and clicked OK. The system acted like it was doing stuff, but then
eventually I landed back on the same "Add Hosts" screen as before:

Am I missing something?

If you deployed with wizard the hosted engine should already be HA
and can run on any host. I’d you look at GUI you will see a crown beside each host that is
capable of running the hostess engine.

There would be nothing to automatically "move" it to one of the remaining
healthy hosts.
