[Ocfs2-users] O2CB heartbeat: Not active

[McKinley, Reid]

Sunil,
Here is the output...(note: nyxlx1 is where we can mount the ocfs2 fs).

[root at nyclx2 ~]# mounted.ocfs2 -d

[root at nyclx1 ~]#

In the /var/log/messages, I see this at the time the mount fails:

Apr 29 12:01:13 nyclx2 kernel: (12430,0):o2net_check_handshake:1163 node

but 103 is required, disconnecting

Thanks again,
Reid

What does "mounted.ocfs2 -d" say on both nodes?

Not /var/log/dmesg. It is /var/log/messages. You could instead
run "dmesg". This is important as it will tell you why the
mount failed.
