-# lustre_server
-# Description: Manages a lustre_server on a shared storage medium.
-# Original Author: Eric Z. Ayers (eric.ayers@compgen.com)
-# Original Release: 25 Oct 2000
-#
-# Rewritten Filesystem agent to lustre_server agent by bschubert@ddn.com
-#
-# usage: ./lustre_server {start|stop|status|monitor|validate-all|meta-data}
-#
-# OCF parameters are as below:
-# OCF_RESKEY_device
-# OCF_RESKEY_directory
-# OCF_RESKEY_options
-#
-#OCF_RESKEY_device : name of block device for the filesystem. e.g. /dev/sda1, /dev/md0
-# Or a -U or -L option for mount, or an NFS mount specification
-#OCF_RESKEY_directory : the mount point for the filesystem
-#OCF_RESKEY_options : options to be given to the mount command via -o
-#
-#
-# NOTE: There is no locking (such as a SCSI reservation) being done here.
-# I would if the SCSI driver could properly maintain the reservation,
-# which it cannot, even with the 'scsi reservation' patch submitted
-# earlier this year by James Bottomley. The patch minimizes the
-# bus resets caused by a RESERVATION_CONFLICT return, and helps the
-# reservation stay when 2 nodes contend for a reservation,
-# but it does not attempt to recover the reservation in the
-# case of a bus reset.
-#
-# What all this means is that if 2 nodes mount the same file system
-# read-write, the filesystem is going to become corrupted. However
-# Lustre provides the Multi-Mount-Protection feature (MMP).
-#
-# As a result, you should use this together with the stonith option
-# and redundant, independent communications paths.
-#
-# If you don't do this, don't blame us when you scramble your disk.
-#
-# Note: the ServeRAID controller does prohibit concurrent acess
-# In this case, you don't actually need STONITH, but redundant comm is
-# still an excellent idea.

-# Copyright Joern Engel <joern@wh.fh-wedel.de>
-# Inspired by Linus Torvalds
-# Original idea maybe from Keith Owens
-# s390 port and big speedup by Arnd Bergmann <arnd@bergmann-dalldorf.de>
-# Modified to have simpler output format by Dan Kegel
-#
-# Usage:
-# objdump -d vmlinux | stackcheck.pl [arch]
-#
-# find <moduledir> -name "*.o" | while read M; do
-# objdump -d $M | perl ~/checkstack.pl <arch> | \
-# sed "s/^/`basename $M`: /" ; done | \
-# awk '/esp/ { print $5, $2, $4 }' | sort -nr
-
-# TODO : Port to all architectures (one regex per arch)
-
-# check for arch
-#
-# $re is used for three matches:
-# $& (whole re) matches the complete objdump line with the stack growth
-# $1 (first bracket) matches the code that will be displayed in the output
-# $2 (second bracket) matches the size of the stack growth
-#
-# use anything else and feel the pain ;)
