> Hello. I have been following the instructions in http://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster to create a cluster on the same subnet with private IPs. I have made sure the hosts files are correct, and time is synced. However when I log into the second node and run pvecm add IP-ADDRESS-CLUSTER the following happens:

You should check that

- Multicast works (Switch configuration)
- there is no firewall between the pve hosts that blocks corosync traffic

If Multicast does not work, you can try to reconfigure corosync to use UDP unicast. You can find an example on your PVE node at /usr/share/doc/corosync-pve/examples/corosync.conf.example.udpu

Helo, 

It happens the same here. Multicast has been tested succesfully following this: 
http://pve.proxmox.com/wiki/Multicast_notes#test_if_multicast_is_working_between_two_nodes_with_omping
So I guess I don't have to configure anything on the switch....

No firewall blocking anything. 
/etc/pve/cluster.conf succesfully replicated, but on the GUI of the first node the nodes appears with a red indicartor and I cannot get properties from them.

Any clue?

Kind regards,
