PVE 3.1 & Cluster with fencing

[gigi]

Hi,

I have installed two servers with proxmox pve 3.1 and have configurate them with HA disponibility with a fence device (APC).
All works fine, the servers can communicate with fence device...

But, because there is a but lol, when some VM are in HA mode and a server crash, the second server reboot the crashed server. OK
When the crashed server reboot and start, he reboot the other server ^o), and take the VMs.
When the rebooted server start, he reboot the other server.
And they constantly restart.

My configuration of cluster :

<?xml version="1.0"?><cluster config_version="155" name="server-clust1">
  <cman expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"/>
  <fencedevices>
    <fencedevice agent="fence_apc" ipaddr="x.x.x.x" login="xxxx" name="apc" passwd="xxxx"/>
  </fencedevices>
  <clusternodes>
    <clusternode name="server-1" nodeid="1" votes="1">
      <fence>
        <method name="power">
          <device name="apc" port="1" secure="on"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="server-2" nodeid="2" votes="1">
      <fence>
        <method name="power">
          <device name="apc" port="2" secure="on"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <rm/>
</cluster>

Thanks for your help !

Yes, that is the behaviour when you configure two_node="1".

I would never use such setup (use 3 nodes, or 2 nodes with qdisk),
