Can anyone please explain why I get this permission denied error? I try starting the script and it fails with a permission denied message. So I create a copy of it and run that instead and that works.

[root@node2 ~]# /etc/init.d/gfs2 stop
Unmounting GFS2 filesystem (/drbd):                        [  OK  ]
[root@node2 ~]# /etc/init.d/gfs2 start
