+spNFS
+-----
+
+An spNFS system consists of a Meta Data Server (MDS), a number of Client machines (C) and a number of Data Servers (DS).
+
+A file system is mounted by the clients from the MDS, and all file data
+is striped across the DSs.
+
+Identify the machines that will be filling each of these roles.
+
+The spnfs kernel will be installed on all machines: clients, the MDS and DSs.
+
+
+Building and installing the spNFS kernel
+----------------------------------------
+
+Get the spNFS kernel from:
+
+	git://linux-nfs.org/~bhalevy/linux-pnfs.git
+
+Use the pnfs-all-latest branch and add these options to your .config file
+
+	CONFIG_NETWORK_FILESYSTEMS=y
+	CONFIG_NFS_FS=m
+	CONFIG_NFS_V4=y
+	CONFIG_NFS_V4_1=y
+	CONFIG_PNFS=y
+	CONFIG_NFSD=m
+	CONFIG_PNFSD=y
+	# CONFIG_PNFSD_LOCAL_EXPORT is not set
+	CONFIG_SPNFS=y
+
+By default, spNFS uses whole-file layouts.  Layout segments can be enabled
+by adding:
+
+	CONFIG_SPNFS_LAYOUTSEGMENTS=y
+
+to your .config file.
+
+Building and installation of kernel+modules is as usual.
+This kernel should be installed and booted on the client, MDS and DSs.
+
+Note that CONFIG_PNFSD_LOCAL_EXPORT must be disabled for spnfs as it
+takes over the pnfs export interface.
+
+Building nfs-utils
+------------------
+
+Get the nfs-utils package containing spnfsd from:
+
+	git://linux-nfs.org/~bhalevy/pnfs-nfs-utils.git
+
+Follow the standard instructions for building nfs-utils.
+
+After building, the spnfsd daemon will be located in utils/spnfsd.  The spnfsd
+daemon will only be needed on the MDS.
+
+
+Installation
+------------
+
+The nfs-utils package contains a default spnfsd.conf file in
+utils/spnfsd/spnfsd.conf.  Copy this file to /etc/spnfsd.conf.
+
+By default, the DS-Mount-Directory is set to /spnfs (see spnfsd.conf).  Under
+this directory, mount points must be created for each DS to
+be used for pNFS data stripes.  These mount points are named by the ip address
+of the corresponding DS.  In the sample spnfsd.conf, there are two
+DSs defined (172.16.28.134 and 172.16.28.141).
+
+Following the sample spnfsd.conf,
+
+	mkdir /spnfs
+
+on the MDS (corresponding to DS-Mount-Directory).  Then
+
+	mkdir /spnfs/172.16.28.134
+	mkdir /spnfs/172.16.28.141
+
+to create the mount points for the DSs.
+
+On the DSs, chose a directory where data stripes will be created by the MDS.
+For the sample file, this directory is /pnfs, so on each DS execute:
+
+	mkdir /pnfs
+
+This directory is specified in the spnfsd.conf file by the DS*_ROOT option
+(where * is replaced by the DS number).  DS_ROOT is specified relative to
+the directory being exported by the DSs.  In our example, our DSs are exporting
+the root directory (/) and therefore our DS_ROOT is /pnfs.  On the DSs, we have
+the following entry in /etc/exports:
+
+	/ *(rw,fsid=0,insecure,no_root_squash,sync,no_subtree_check)
+
+N.B. If we had created a /exports directory and a /pnfs directory under
+/exports, and if we were exporting /exports, then DS_ROOT would still be /pnfs
+(not /exports/pnfs).
+
+It may be useful to add entries to /etc/fstab on the MDS to automatically
+mount the DS_ROOT file systems.  For this example, our MDS fstab would
+contain:
+
+	172.17.84.128:/pnfs /spnfs/172.17.84.128 nfs    defaults        1 2
+	172.17.84.122:/pnfs /spnfs/172.17.84.122 nfs    defaults        1 2
+
+The DS mounts must be performed manually or via fstab at this time (automatic
+mounting, directory creation, etc. are on the todo list).  To perform I/O
+through the MDS, the DS mounts MUST use NFSv3 at this time (this restriction
+will eventually be removed).
+
+
+On the MDS, choose a file system to use with spNFS and export it, e.g.:
+
+	/ *(rw,fsid=0,insecure,no_root_squash,sync,no_subtree_check,pnfs)
+
+Make sure nfsd and all supporting processes are running on the MDS and DSs.
+
+
+Running
+-------
+
+If rpc_pipefs is not already mounted (if you're running idmapd it probably is),
+you may want to add the following line to /etc/fstab:
+
+	rpc_pipefs    /var/lib/nfs/rpc_pipefs rpc_pipefs defaults     0 0
+
+to automatically mount rpc_pipefs.
+
+With spnfsd.conf configured for your environment and the mounts mounted as
+described above, spnfsd can now be started.
+
+On the MDS, execute spnfsd:
+
+	spnfsd
+
+The executable is located in the directory where it was built, and
+may also have been installed elsewhere depending on how you built nfs-utils.
+It will run in the foreground by default, and in fact will do so despite
+any options suggesting the contrary (it's still a debugging build).
+
+On the client, make sure the nfslayoutdriver module is loaded:
+
+	modprobe nfslayoutdriver
+
+Then mount the file system from the MDS:
+
+	mount -t nfs4 -o minorversion=1 mds:/ /mnt
+
+I/O through the MDS is now supported.  To use it, do not load the
+nfslayoutdriver on the client, and mount the MDS using NFSv4 or 4.1
+(NFSv2 and v3 are not yet supported).
+
+You may now use spNFS by performing file system activities in /mnt.
+If you create files in /mnt, you should see stripe files corresponding to
+new files being created on the DSs.  The current implementation names the
+stripe files based on the inode number of the file on the MDS.  For example,
+if you create a file foo in /mnt and do an 'ls -li /mnt/foo':
+
+	# ls -li foo
+	1233 -rw-r--r-- 1 root root 0 Nov 29 15:54 foo
+
+You should see stripe files on each under /pnfs (per the sample) named
+1233.  The file /pnfs/1233 on DS1 will contain the first <stripe size> bytes
+of data written to foo, DS2 will contain the next <stripe size> bytes, etc.
+Removing /mnt/foo will remove the corresponding stripe files on the DSs.
+Other file system operations should behave (mostly :-) as expected.
+
+
+Layout Segments
+---------------
+
+If the kernel is compiled to support layout segments, there will
+be two files created under /proc/fs/spnfs for controlling layout
+segment functionality.
+
+To enable layout segments, write a '1' to /proc/fs/spnfs/layoutseg, e.g.:
+
+	echo 1 > /proc/fs/spnfs/layoutseg
+
+Layout segments can be disabled (returning to whole-file layouts) by
+writing a '0' to /proc/fs/spnfs/layoutseg:
+
+	echo 0 > /proc/fs/spnfs/layoutseg
+
+When layout segments are enabled, the size of the layouts returned can
+be specified by writing a decimal number (ascii representation) to
+/proc/fs/spnfs/layoutsegsize:
+
+	echo 1024 > /proc/fs/spnfs/layoutsegsize
+
+The value'0' has a special meaning--it causes the server to return a
