Manually umounting /dlm is not a good idea. Let the o2cb script
handle that.<br>
It'll be easier to diagnose if you followed the steps I had listed.<br>

</font><br>
</div>
<tt>So by default, the hb is supposed to stop on umount.<br>
<br>
Do:<br>
# find
/sys/kernel/config/cluster/<CLUSTERNAME>/heartbeat/* -type
d | xargs basename<br>
77D95EF51C0149D2823674FCC162CF8B<br>
<br>
This will list the active heartbeats.<br>
<br>
For each hb, do:<br>
# ocfs2_hb_ctl -I -u 77D95EF51C0149D2823674FCC162CF8B<br>
77D95EF51C0149D2823674FCC162CF8B: 1 refs<br>
<br>
Notice the references. > 0 is active heartbeat.<br>
<br>
If you are sure there are no mounts and "ls /dlm" also has not
entries,<br>
then hb failed to stop for some reason.<br>
<br>
To stop, do:<br>
# ocfs2_hb_ctl -K -u 77D95EF51C0149D2823674FCC162CF8B<br>
<br>
It could be that this is failing. What do you see?<br>
<br>
I remember we had a problem in this in tools 1.4.1. But that was<br>
fixed in 1.4.2.<br>
