use iscsi to share the storage. If the master fails it will fail over to
the other.</p>
<p style="margin: 0 0 1em 0; color: black;">You have one up that will act
as the iscsi storage and jump between the hosts.</p>

<p>Just genuinely curious, how do you avoid split-brain situations
with a 2-node setup (be it drbd, gluster or anything else)?<br>

have used that
to build a cluster for two servers. It need some more work

<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>
