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