[Ocfs2-users] Unable to stop cluster as heartbeat region still active

[Laurentiu Gosu]

Hi,
I have a 2 nodes ocfs2 cluster running UEK 2.6.32-100.0.19.el5, 
ocfs2console-1.6.3-2.el5, ocfs2-tools-1.6.3-2.el5.
My problem is that all the time when i try to run /etc/init.d/o2cb stop 
it fails with this error:
     Stopping O2CB cluster CLUSTER: Failed
     Unable to stop cluster as heartbeat region still active
There is no active mount point. I tried to manually stop the heartdbeat 
with "ocfs2_hb_ctl -K -d /dev/mapper/volgr1-lvol0 ocfs2" (after finding 
the refs number with "ocfs2_hb_ctl -I -d /dev/mapper/volgr1-lvol0 "). 
But even if refs number is set to zero the "heartbeat region still 
active" occurs.
How can i fix this?

Thank you in advance.
Laurentiu.
