For HA you will need some kind of storage available to all the compute nodes in the cluster. 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.
