	# Filesystem
	# Description: Manages a Filesystem on a shared storage medium.
	# Original Author: Eric Z. Ayers (eric.ayers@compgen.com)
	# Original Release: 25 Oct 2000
	#
	# usage: ./Filesystem {start\|stop\|status\|monitor\|validate-all\|meta-data}
	#
	# OCF parameters are as below:
	# OCF_RESKEY_device
	# OCF_RESKEY_directory
	# OCF_RESKEY_fstype
	# 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_fstype : optional name of the filesystem type. e.g. ext2
	#OCF_RESKEY_options : options to be given to the mount command via -o
	#
	#
	# An example usage in /etc/ha.d/haresources:
	# node1 10.0.0.170 Filesystem::/dev/sda1::/data1::ext2
	# or
	# node1 10.0.0.170 Filesystem::-Ldata1::/data1::ext2
	# or
	# node1 10.0.0.170 Filesystem::server:/data1::/data1::nfs::ro
	#
	# This assumes you want to manage a filesystem on a shared (scsi) bus.
	# Do not put this filesystem in /etc/fstab. This script manages all of
	# that for you.
	#
	# If you are interested in High Availability, you will probably also want
	# some sort of external hardware RAID controller in front of the actual
	# disks. I don't mean a RAID controller embedded in the host controller -
	# it has to be an external controller.
	#
	# It can also be an internal RAID controller if the controller supports
	# failover. IBM's ServeRAID controller does this, and it automatically
	# prohibits concurrent access too, so it's pretty cool in this application.
	#
	# There is a script for software RAID-1 included in this directory. Right
	# now, I wouldn't recommend using software RAID (see notes in the Raid1 script)
	#
	# 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.
	#
	# 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.
