If you have no external storage and few nodes, I think your best option for storage is gluster , and the minimum number of nodes you will need for HA is 3 (the third gluster node can be metadata-only, but you still need that third node to give you quorum, avoid split-brains and have something that you can call "HA" with a straight face.

Looking for a design advise on oVirt provisioning. I'm running a PoC lab on single bare-metal host (suddenly it was setup with just Local Storage domain) and no I'd like to rebuild the setup by making a cluster of 2 physical servers, no external storage array available. That are the options here? is there any options to build cheap HA cluster with just 2 servers?
Thanks in advance!
