Hi Mike,

1. I recommend "service ccsd stop" rather than killall ccsd.
2. In theory, this script should not be necessary on a RHEL, Fedora Core 
or centos box
    if you have your service scripts set up and chkconfig'ed on.  When 
you do
    /sbin/reboot, the service scripts are supposed to run in the correct 
order
    and take care of all this for you. Shudown should take you to 
runlevel 6,
    which should run the shutdown scripts in /etc/rc.d/rc6.d in the Kxx 
order.
    The httpd script should stop that service, then the
    the gfs script should take care of unmounting the gfs file systems 
at "stop".
    The clvmd script should take care of deactivating the vgs.  And the 
Kxx numbers
    should be set properly at install time to ensure the proper order.
    If there's a problem shutting down with the normal scripts, perhaps 
we need to
    file a bug and get the scripts changed.
