Did you reformat the volume recently? or, when did you format last?

looks like we have different UUIDs. Where is this coming from??

No improvment :(

So it is not mounted. But we still have a hb thread because
hb could not be stopped during umount. The reason for that
could be the same that causes ocfs2_hb_ctl to fail.
Do:
mounted.ocfs2 -d

There is no /dev/dm-2 mounted.

mount -t debugfs debugfs /sys/kernel/debug
Then list that dir.
Also, do:
ocfs2_hb_ctl -l -d /dev/dm-2
Be careful before killing. We want to be sure that dev is not mounted.

I think i have to enable debug first somehow..?

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.
