Hello,
Is there documentation anywhere for adding a 4th compute-only host to an existing HCI cluster?

I did the following earlier today:

Installed RHEL 8.4 onto the new (4th) host
Setup an NFS share on the host
Attached the NFS share to oVirt as a new storage domain

I then turned the NFS share into a "backup domain"

Once that was done, I installed ovirt-release44.rpm, followed by some ovirt packages:

yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm
yum install cockpit-ovirt-dashboard vdsm-gluster ovirt-host

I then logged into the oVirt Manager Web UI, navigated to Hosts, and clicked on New

I successfully added the new host to the cluster

Once this was all done, load average on all 3 of my original HCI nodes started to go through the roof.

I've seen servers' load average go through the roof before when NFS shares are down, so I suspect that something happened to the NFS share when I went to add the host as a compute node.

In an effort to get things stabilized, I wound up yanking the new host out of oVirt, as well as the NFS share, at which point things did stabilize again.

My goal here:

Setup the host as a compute-only host (don't participate in the gluster cluster)
Setup the NFS share for backup purposes

Writing this email and reviewing my bash history, I think one of the places I went wrong was I installed vdsm-gluster. I don't think I need that, do I?

Is what I'm trying to do possible?
