Sorry. The tracing was not enabled due to my foul up.
The echos to turn on are as follows:
echo super allow > /proc/fs/ocfs2_nodemanager/log_mask
echo entry allow >/proc/fs/ocfs2_nodemanager/log_mask
echo exit allow >/proc/fs/ocfs2_nodemanager/log_mask
Load the cluster stack (service o2cb start).
Enable tracing as above.
"cat /proc/fs/.../log_mask" should show the tracing enabled.
Mount the volume.
Wait few secs for the syslog to stop dumping before disabling
the tracing as follows:
echo super off > /proc/fs/ocfs2_nodemanager/log_mask
echo entry deny >/proc/fs/ocfs2_nodemanager/log_mask
echo exit deny >/proc/fs/ocfs2_nodemanager/log_mask
Email the /var/log/messages.
