Hello all,
Found the problem (at least I think so), but not the solution.
As I have an existing Gluster setup (quite complex one) this was the first
time I didn't use the "Hyperconverged gluster wizard" (via cockpit), but
used the "hosted-engine --deploy" cli instead (which I usually use to
deploy single host setups).
The idea being: Deploy the first hosts (via cli) and then add the two
additional hosts via compute->host->create.
For some odd reason I seem to remember this method was an approved way of
deploying an hyperconverged gluster setup, in cases you don't want to let a
wizard create the gluster bricks. Am I wrong?
A. In case I'm wrong: How can I deploy a 3 host hyperconverged setup,
_while_ using the preexisting gluster bricks (data/export/iso)?
B. I did a clean redeploy (via cockpit -> hosted engine -> hosted engine
deploy) and the cluster version is still 4.4 (and given the fact it only
deploys a single host, there's no way to upgrade it to 4.5, as I cannot put
the host into maintenance and I cannot add additional hosts).

Thanks for the prompt reply.
I assume I can safely ignore the "Upgrade cluster compatibility" warning
until libvirt 6.6 gets pushed to CentOS 8.3?
We are working on releasing AV 8.3, hopefully it will be available soon,
but until that happen you have no way how to upgrade to CL 4.5 and you just
need to stay in 4.4
Understood.
Thanks again.

Just updating that oVirt 4.4.4 released yesterday comes with Advanced
Virtualization 8.3 so you can now enable CL 4.5.
Sadly enough, even post-full-upgrade (engine + hosts) something seems to
be broken.
In the WebUI, I see all 3 hosts marked as "up".
But when I run hosted-engine --vm-status (or migrate the hosted engine),
only the first (original deployed) host is available.
I tried "reinstalling" (from the WebUI) the two hosts, no errors, no
change.
I tried upgrading the cluster again, host 2 / 3 (the "missing" hosts)
upgrade is successful; hosts1 fails (cannot migrate the hosted engine).
Any idea what's broken?

I'll remove the problematic hosts, re-add them, and reconfigure the
network(s). Let's see if it works.

Sorry for the noise. No go.
Cleaned up the hosts via ovirt-hosted-engine-cleanup + reboot, tried
"adding" them again, to no avail.
Host marked as "up" in WebUI, network correctly configured, however,
hosted-engine.conf isn't being created (see log below),
ovirt-ha-broker/agent services cannot start and vm-status only shows one
host.
