[Ocfs2-users] o2net_connect_expired

[Sunil Mushran]

In short, node 1's attempt to connect to node 0 failed. See the
messages file on node 0. If there is no evidence of a connect request,
check if you have some sort of firewall setup. If so, open up the
required port(s).

You could also use tcpdump to trap traffic on the required port /
ethernet interface to debug the issue.
