I know that the GUi should work in most setups, as oVirt is the upstream of the Red Hat Gluster Storage Console. Despite RH being an open-source company, it's also trying to sell support contracts and thus it's not an open-documentation company - they need to make money after all. I know that oVirt is 'hardcoded' (this is intentional) to replica 3 when upgrading, so you add 2 nodes, then prepare the bricks and modify the volumes to 'replica 3', then add a new cycle of 3 nodes and repeat.

It's an unfortunate thing that the GUI assumptions can be counter intuitive in many regards, but i can confirm you can do this in the GUI as long as the gluster volumes was created in the GUI in the first place. If not, it will not show up as a volume. > Now whether or not oVirt will then treat such a hand-made 1->3 node > cluster like a 3 node HCI built by itself is something I've never > tried. It will as long as the above gluster volume requirement is met, although if using gluster for hosted engine you typically end up doing that by hand. > If I had successfully tested the 3 node to 6 and 9 node expansion, I'd > perhaps be more confident.

I do this quite often, add hosts to compute, add bricks to a gluster volume, done deal. However we do tend to use ZFS underneath which is outside the scope of oVirt. It allows us to re-use existing storage elements (providing there is enough space) to create temporary volumes to assist in the process. _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/M5VC5AP6V6BV2VNQT46DKNF253W3ECPL/
