I added a VM to HA in node prox1, and now the output is the same.
The "pvecm status" looks a bit different:
On the 2 nodes - udpu:
root@prox1:~# pvecm status
Date: Tue Apr 5 17:01:15 2016
Quorum provider: corosync_votequorum
we have cluster configuration which consists in a 2 nodes - unicast udpu (multicast not available).
The cluster is up and running, I added and removed a test machine from HA.
The question is, we have the following output for "ha-manager status", on this cluster, two node up and running...
