I have already setup a two node HA Proxmox cluster configuring as per

So I have a primary/primary DRBD resource (yes I configured fencing
correctly).
I'm wondering if I can set up third (remote) machine and have a
three-way replication setup as per
<a class="moz-txt-link-freetext" href="http://www.drbd.org/users-guide-8.3/s-three-nodes.html">http://www.drbd.org/users-guide-8.3/s-three-nodes.html</a>
Anyone has already experiment such scenario?

I'm not 100% certain, but the idea is begging the question: Which of
your primaries should be the prospective peer of your third node?

In my setup I can see the upper layer resource on "primary" and
"backup" but have no idea how to access the resource on "secondary"
in case primary crashes.<br>
Shoul I access the lower layer resource on "secondary" (after
promoting it to primary)?<br>
<br>
Thanks in advance<br>
