Thanks for the info on how to shut the heartbeat down.. I haven't had a chance to test it as of yet.
I had previously found info on /dlm being mounted, I unmounted it on both nodes & heartbeat still stayed active. Also post a reboot, the process of offlining the cluster did not return an error anymore but a status check still indicated heartbeat was active & an attempt to unload then threw back the heartbeat active error.

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

This is what I see, even happens if using force-offline option: [root]# /etc/init.d/o2cb force-offline clustername Stopping O2CB cluster clustername Failed Unable to stop cluster as heartbeat region still active I have no ocfs2 filesystems curently mounted on either node (2 node cluster) [root]# mount | grep ocfs [root]# Versions of ocfs2 as below: [root]# rpm -qa | grep ocfs ocfs2-tools-1.4.4-1.el5.x86_64 ocfs2-tools-devel-1.4.4-1.el5.x86_64 ocfs2console-1.4.4-1.el5.x86_64 ocfs2-2.6.18-128.el5-1.4.4-1.el5.x86_64 ocfs2-tools-debuginfo-1.4.4-1.el5.x86_64 Redhat Linux kernel version: 2.6.18-128.el5 A collegue of mine stated that he usually disables all ocfs2 from the startup scripts, comments out the filesystems in /etc/fstab & reboots, is there another option to get the heartbeat offline or is this an ocfs2 or Linux bug I am encountering here??
