Not to give you any false hope, but when I recently reinstalled my oVirt
4.4.2 cluster, I left the gluster disks alone and only reformatted the
OS disks. Much to my surprise, after running the oVirt HCI wizard on
this new installation (using the exact same gluster settings as before),
the original contents of my gluster-based data domain were still intact.
I certainly wouldn't count on this behavior with any important data, though.

Before you reinstall the node , you should use 'gluster volume
remove-brick <VOL> replica <old number - 1> ovirt_node:/path-to-brick' to
reduce the volume to replica 2 (for example). Then you need to 'gluster
peer detach ovirt_node' in order to fully cleanup the gluster TSP.
You will have to remove the bricks that are on that < ovirt_node > before
detaching it.
Once you reinstall with EL 8, you can 'gluster peer probe
<reinstalled_ovirt_node>' and then 'gluster volume add-brick <VOL> replica
<current count + 1> reinstalled_ovirt_node:/path-to-brick.
Note that reusing bricks is not very easy, so just wipe the data via
'mkfs.xfs -i size=512 /dev/block/device'.
Once all volumes are again a replica 3 , just wait for the healing to go
over and you can proceed with the oVirt part.

My confusion is that those documents do not describe any gluster related
tasks for Ovirt Nodes. When I take a node down and install Ovirt Node 4.4
on it, won't all the gluster bricks on that node be lost? The part
describing "preserving local storage", that isn't anything about Gluster,
correct?

I have 3 nodes running node ng 4.3.9 with a gluster/hci cluster. How
do I upgrade to 4.4? Is there a guide?
