Ovirt can be installed on as little as one node ,but for a proper HA setup you should have at least three nodes. Hci uses gluster and needs a replica 3 or replica 3 arbiter 1 configuration. With arbiter you need less storage as it only holds metadata so you might be able to put a third server in your mix without having to spend a lot on storage for it. I would not attempt HA with anything less than three severs unless you are using external storage such as nfs. On Sat, Jun 15, 2019 at 3:42 PM <adam.fasnacht@gmail.com> wrote:
Hello,
I just discovered oVirt, and before installing, I'm already a fan. I have a question regarding the number of nodes needed for a cluster. My main end goal, is to have HA, where I can have live migrations. I currently have 2 nodes (2 Dell R630s) that have a ton of local SSD storage on them. Is it possible to setup oVirt with just 2 nodes, and have an HA "hyper converged" style cluster?
I can't seem to find a solid answer for this question. I've read the documentation, as well as consulted Google. I seem to get mixed answers. Is this possible?
