Well, that's why I really want a theory of operation here, because removing a host as a gluster peer might just break something in oVirt... And trying to fix that may be not trivial either.
It's one of those cases where I'd just really love to have nested virtualization work better so I can snapshot an virtualized HCI cluster before I do these things, so I can revert with a click or three.
And what really irritates me is that even hosts that do not contribute bricks to a volume show up when I do a volume status.
Mostly because I've had situations where I had the typical 3 node HCI with an additional 5 compute-only nodes and when I was updating these with some degree of overlap (several unloaded hosts at once), all of a sudden vmstore/data/engine would go down for lack of quorum.... just because non-participating hosts were not available!!
So again, if one of the oVirt developers could shine a light into this, it would be very much appreciated.
