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

[Josh Gray]

Thanks for the reply..     Is this 4.x version you are running?   I see you
are doing `service cman stop leave`   instead of cman_tool,      I’m still
getting the same results putting a pause in there.

Femced isn’t a standalone process in 5.0 as far as I can tell.  If it is,
then is that the one process stopping me from leaving the cluster?
