[Ocfs2-users] Cant stop o2cb - Unable to stop cluster as heartbeat region still active

[neil campbell]

Hi all,

I am trying to shut-down the nodes in our cluster, but two of the fourteen nodes will not stop OCFS, returning the error "Unable to stop cluster as heartbeat region still active"

I'd like your help in identify why this is, and how to fix it.

Using RedHat 4.8 and ocfs 1.2.9

# /etc/init.d/o2cb stop
Stopping O2CB cluster UATocfs2: Failed
Unable to stop cluster as heartbeat region still active

# modinfo ocfs2
filename:       /lib/modules/2.6.9-89.0.26.ELsmp/kernel/fs/ocfs2/ocfs2.ko
license:        GPL
author:         Oracle
version:        1.2.9 CF6A7A44EA2581415F3D612
description:    OCFS2 1.2.9 Mon Dec  5 14:27:38 EST 2011 (build e5c3135c8cbf75f2620ff4c782d634f1)
depends:        ocfs2_nodemanager,ocfs2_dlm,jbd,debugfs
vermagic:       2.6.9-89.0.26.ELsmp SMP gcc-3.4


There are no mounts, either in /proc/mounts or from mtab

# cat /proc/mounts | grep -i ocfs
# mount | grep -i ocfs
#

On one of the nodes with the issue it only shows a single entry for heartbeat

# ls -lR heartbeat/
heartbeat/:
total 4
drwxr-xr-x  2 root root 4096 Mar 15  2013 47B9FA48BFE74772AF3E6AAB1D3B3F9C

heartbeat/47B9FA48BFE74772AF3E6AAB1D3B3F9C:
total 16
-rw-r--r--  1 root root 4096 Mar 15  2013 block_bytes
-rw-r--r--  1 root root 4096 Mar 15  2013 blocks
-rw-r--r--  1 root root 4096 Mar 15  2013 dev
-rw-r--r--  1 root root 4096 Mar 15  2013 start_block

It does show the correct multipath LUN used by OCFS 

# cat /config/cluster/UATocfs2/heartbeat/47B9FA48BFE74772AF3E6AAB1D3B3F9C/dev
emcpowerq1
#


Appreciate your help in getting the o2cb services stopped cleanly!

Thanks
Neil
