[Linux-cluster] Shutdown/startup

[Dan B. Phung]

I don't know if it's correct....but I have init scripts that 
shut down the services in order:

blade07:phung:) cat /etc/init.d/gfs_all
#!/bin/sh

case "$1" in
        start|restart)
                for i in ccsd cman fenced clvmd_init gfs; do
                        sh /etc/init.d/$i start
                done
                ;;
        stop|reload|force-reload)
                for i in gfs clvmd_init fenced cman ccsd; do
                        sh /etc/init.d/$i stop
                done
                ;;
    *)
        echo $"Usage: $0 {start|stop}"
        ;;
esac
