Hi Gilberto, I Have been testing Proxmox HA without fencing device and works. I test with 2 nodes Proxmox but have not tried with 3 nodes. I also posting in my blog about howto : http://ahmad.imanudin.com/2013/08/18/tips-proxmox-configure-proxmox-high-availability-without-fencing-device/ with indonesian language :D This is my Cluster configuration ************************************* cp /etc/pve/cluster.conf /etc/pve/cluster.conf.new nano /etc/pve/cluster.conf.new *<?xml version="1.0"?>* *<cluster config_version="5" name="excellent">* *<cman expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"/>* *<fencedevices>* *<fencedevice agent="fence_manual" name="human"/>* *</fencedevices>* *<clusternodes>* *<clusternode name="pve1" nodeid="1" votes="1">* *<fence>* *<method name="single">* *<device name="human" nodename="pve1"/>* *</method>* *</fence>* *</clusternode>* *<clusternode name="pve2" nodeid="2" votes="1">* *<fence>* *<method name="single">* *<device name="human" nodename="pve2"/>* *</method>* *</fence>* *</clusternode>* *</clusternodes>* *</cluster>* Note : excellent = My Cluster name pve1 = Hostname for Proxmox 1 (node 1) pve2 = Hostname for Proxmox 2 (node 2) Importan : You must edit config_version every change cluster configuration. Next you can configure VM with clue from here : http://pve.proxmox.com/wiki/High_Availability_Cluster and try to power off host Proxmox. Example : I have VM running on Proxmox 1 (node1) and have been configured HA. Forced off node 1 and run this command from node 2 to take over VM fence_ack_manual pve1 (pve1 is hostname node 1) after that, you must confirm with answer *absolutely* Thanks -- ** Best Regards, Ahmad Imanudin - Sharing is Beautiful !
