Unicast but...Waiting for quorum [PVE 2.3]

Hi,

Since it is not possible to have multicast with OVH's dedicaded servers, I tried to use unicast inestead. I followed the Wiki http://pve.proxmox.com/wiki/Multicas...d_of_multicast But, after that : Same thing : Waiting for quorum

Node1 is the cluster and Node 2 have to be a cluster member (of node 1)

Here's my corosync log on node 2 when I do "pvecm add node1" : http://pastebin.com/HZip6DqD

WHat's the problem ? The cluster seems to use Unicast...

Best regards
