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

[McKinley, Reid]

We can bring up the ocfs2 cluster on 1 of 2 nodes only.  So, it appears
that it's not specific to only one specific node.  Right now we have the
ocfs2 heartbeat operational on node2 (node1 in the cluster.conf).

Here are the results of the mount and tcpdump.

[root at nyclx1 ~]# mount -t ocfs2 /dev/mapper/mpath1 /oragrid
mount.ocfs2: Transport endpoint is not connected while mounting
/dev/mapper/mpath1 on /oragrid. Check 'dmesg' for more information on
this error.
[root at nyclx1 ~]#

Do:
$ tcpdump -i ethX -s 2500 -ttt 'port 7777'

on both nodes. Replace ethX with the appropriate interface.
Then issue the mount command on node 1. Do you see the traffic
on node 0?
