	# 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_statusfile_prefix
	#
	#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
	#OCF_RESKEY_statusfile_prefix : the prefix used for a status file for monitoring
	#
	#
	-# 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,
	+# on a replicated device (such as DRBD), or a network filesystem (such
	+# as NFS or Samba).
	#
	-# 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.
	+# NOTE: If 2 or more nodes mount the same file system read-write, and
	+# that file system is not designed for that specific purpose
	+# (such as GFS or OCFS2), and is not a network file system like
	+# NFS or Samba, then the filesystem is going to become
	+# corrupted.
	#
	-# 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.
	+# 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.

	<parameter name="statusfile_prefix">
	<longdesc lang="en">
	The prefix to be used for a status file for resource health
	monitoring. If this parameter is set, then the monitor operation will
	read from, and optionally write to, a file whose filename is
	constructed from "directory", "statusfile_prefix", and the host
	name. Its expected content is the name of the resource. If status
	files should live in their own directory, be sure to add a trailing
	slash ("/") to "statusfile_prefix".

	If the "monitor" operation is configured with a "depth" of 0, then the
	status file is just created once (on resource startup, and only if it
	does not already exist), and subsequently read. If "depth" is greater
	than 0, then the status file is periodically read and re-written.

	Note that if the filesystem is mounted read-only (NFS mounted from a
	read-only export, for example), and you have configured this
	parameter, then you must create the status file manually or the
	resource will fail on start.

	Note also that for monitoring with a "depth" of greater than 0, the
	status file must be writable by root. This is not always the case
	with an NFS mount, as NFS exports usually have the "root_squash"
	option set. In such a setup, you must either use read-only monitoring
	(depth=0), export with "no_root_squash" on your NFS server, or grant
	world write permissions on the directory where the status file is to
	be placed.
