I did a fresh install and added the second note through ssh from the first node. This way i was able to add the node with pvecm add [ip first node].
However the cluster works for a couple of minutes and than brokes. Everythime i reboot the servers, the cluster will run for a couple of minutes and the will be broke.

ls -lh /etc/pve output server1 gives

What can be the problem?
 
Cluster is working now. I added transport: udpu at /etc/pve/corosync.conf.

I have a other issue now. When i whan to create a pveceph createmon i get the message
unable to find local address within network '10.91.219.61/32'

My intern network has follow ips from online.net
server1 10.91.219.61
server2 10.91.218.150
the are connected in the same group with the RPN interface from online.net

The ips are pingable from the 2 servers.
To add the network i did the follow command on server1
pveceph init --network 10.91.219.61/32
All other prefix give a message "invalide prefix" and this 32 prefix give me the message unable to find local address

how can i fix this?

I think the issue is that the 2 private ip's are 2 different subnets.
Bouth ip's are pingable from bouth servers
