<p>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.<br>

<div>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 </div>
<div>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? </div>
