I used how to run "mv" to the pid file.

 The other case also is the same situation. When we already run
"boothd -l other.pid" on node, the lockfile exists in the other place.
So, $lockfile doesn't exist in the start and stop of RA.

 I think that it is better to take account of  the existence of
lockfile or $pidnum, because /proc/cmdline may happen to fulfill this
if. For example, anything RA includes the check if pid is the empty.

anything_status() {
        if test -f "$pidfile"
        then
                if pid=`getpid $pidfile` && [ "$pid" ] && kill -s 0 $pid
                then
                        return $OCF_SUCCESS
                else
                        # pidfile w/o process means the process died
                        return $OCF_ERR_GENERIC
                fi
        else
                return $OCF_NOT_RUNNING
        fi
}
