[Linux-cluster] Cman tool leave remove, device or resource busy



I see in the FAQ the proper way to leave a cluster is with 'cman_tool leave
remove'  I am getting a  'device or resource busy' error when I do that even
with GFS mounts removed and stopped.   What am I missing?  The only service
I see up is a "fence" type called "default"  do I have to stop one more
thing?

Basically doing this:

service nfs stop
umount /export
service gfs stop
service rgmanager stop
service clvmd stop
cman_tool leave remove

Tells me this:
cman_tool: Error leaving cluster: Device or resource busy


Full snip from the server:
