Sorry, this is dangerously wrong.
$OCF_NOT_RUNNING should only be returned if the resource is CLEANLY
stopped. If you return this for failed states, you'll confuse some
Return $OCF_ERR_GENERIC if in doubt; ocf-shellfuncs defines some more
exit codes (which also means this file needs to be sourced before the
exit codes can be returned), which are described in the OCF RA API
