Hello,

First thing to check out is your firewall / iptables.

Put your firewall down on both nodes with 'service iptables stop' and then do 'service drbd restart' on both nodes.

If that works, then your problem is that you have not mutually opened the ports defined for each drbd resource in the /etc/drbd.conf file.
