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:
