[Ocfs2-users] O2CB heartbeat not active on 2nd node

[Sunil Mushran]

Did you have tcpdump running on a terminal when you attempted
the mount on another terminal? Is the interface and port correct?

It is one thing to not see the packets on the nyclx2. But what
confuses me is that there is no traffic on nyclx1 too.
