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

[McKinley, Reid]

Thanks for your push on this.  I don't know why I didn't check this
before.

It looks like we have a problem with our interconnect.  Our SA is
checking the hardware now.

[root at nyclx1 ~]# more /etc/ocfs2/cluster.conf
node:
        ip_port = 7777
        ip_address = 192.168.0.218
        number = 0
        name = nyclx1
        cluster = tiaa

node:
        ip_port = 7777
        ip_address = 192.168.0.217
        number = 1
        name = nyclx2
        cluster = tiaa

cluster:
        node_count = 2
        name = tiaa

[root at nyclx1 ~]# ping 192.168.0.217

Do on both nodes:
$ netstat -ta --numeric-ports

Maybe port 7777 is already in use.

Check your setup again. Ensure cluster.conf is the same on both nodes.
And that the ips are correct. That tcpdump was capturing
the traffic on the correct interface. etc. etc.
