Lustre-server

This is a script that I wrote in order to start and stop a lustre server.

#!/bin/bash
#
# luster-server This shell script takes care of starting and stopping
#               a Lustre server.
#
# chkconfig: 345 27 73

# Source function library.

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
