Hello<br>
<br>
We have here a cluster created with 3 nodes and a simple storage...<br>
It's just to test porposes...<br>
There is no fence devices, for now.<br>
After setting up all Proxmox Hosts and VM's, when I turn off a VM on<br>
node1, for example, the VM is started on node2.<br>
But when I plugged off the network cable, the some doesn't happen!<br>
<br>
Why? Because the cluster is without fence device??<br>
<br>
Thanks...<br></blockquote><div><br></div><div>Hi Gilberto,<br></div><div><br></div><div style>I Have been testing Proxmox HA without fencing device and works.
