[Ocfs2-users] Heartbeat stays active & stops o2cb shutdown

[Sunil Mushran]

So by default, the hb is supposed to stop on umount.

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.
