[ofa-general] new NFS/RDMA instructions for 2.6.25-rc1

[James Lentini]

Linux 2.6.25 will be the first official kernel release to contain the
NFS/RDMA server. With the client and server now both available in 
2.6.25-rc1, we've simplified our NFS/RDMA installation instructions.
The new instructions are available here:
 
 http://nfs-rdma.sourceforge.net/Documents/README

Any reason not to add that to the linux tree, say in
Documentation/filesystems/nfs-rdma.txt?

That sounds like a good idea Bruce. The current document is strictly a 
HOWTO. Should we add sections on the design and implementation?

Sure, that'd be great.  But I think it'd be fine to submit the howto
pretty much as it is and add the rest later.

Bruce,

These are ready to include in what ever kernel version you see fit.

+
+Overview
+~~~~~~~~
+
+  This document describes how to install and setup the Linux NFS/RDMA client 
+  and server software.
+
+  The NFS/RDMA client was first included in Linux 2.6.24. The NFS/RDMA server 
+  was first included in the following release, Linux 2.6.25.
+
+  In our testing, we have obtained excellent performance results (full 10Gbit 
+  wire bandwidth at minimal client CPU) under many workloads. The code passes 
+  the full Connectathon test suite and operates over both Infiniband and iWARP 
+  RDMA adapters. 
+
+Getting Help
+~~~~~~~~~~~~
+
+  If you get stuck, you can ask questions on the
+
+                nfs-rdma-devel@lists.sourceforge.net
+  
+  mailing list. 
+
+Installation
+~~~~~~~~~~~~
+
+  These instructions are a step by step guide to building a machine for
+  use with NFS/RDMA.
+
+  - Install an OpenFabrics-compatible RDMA card
+
+    Any device that is compatible with the OpenFabrics.org software stack is 
+    acceptable.
+
+    Testing has been performed using several Mellanox-based IB cards, the 
+    Ammasso AMS1100 iWARP adapter, and the Chelsio cxgb3 iWARP adapter.
+
+  - Install a Linux distribution and tools
+
+    The first kernel release to contain both the NFS/RDMA client and server was 
+    Linux 2.6.25  Therefore, a distribution compatible with this and subsequent 
+    Linux kernel release should be installed.
+
+    The procedures described in this document have been tested with
+    distributions from Red Hat's Fedora Project (http://fedora.redhat.com/).
+
+  - Install nfs-utils-1.1.1 or greater on the client
+
+    An NFS/RDMA mount point can only be obtained by using the mount.nfs 
+    command in nfs-utils-1.1.1 or greater. To see which version of mount.nfs 
+    you are using, type:
+
+    > /sbin/mount.nfs -V
+
+    If the version is less than 1.1.1 or the command does not exist, 
+    then you will need to install the latest version of nfs-utils. 
+
+    Download the latest package from:
+
+    http://www.kernel.org/pub/linux/utils/nfs
+
+    Uncompress the package and follow the installation instructions.
+
+    If you will not be using GSS and NFSv4, the installation process 
+    can be simplified by disabling these features when running configure:
+
+    > ./configure --disable-gss --disable-nfsv4
+
+    For more information on this see the package's README and INSTALL files.
+
+    After building the nfs-utils package, there will be a mount.nfs binary in 
+    the utils/mount directory. This binary can be used to initiate NFS v2, v3, 
+    or v4 mounts. To initiate a v4 mount, the binary must be called mount.nfs4. 
+    The standard technique is to create a symlink called mount.nfs4 to mount.nfs.
+
+    NOTE: mount.nfs and therefore nfs-utils-1.1.1 or greater is only needed 
+    on the NFS client machine. You do not need this specific version of 
+    nfs-utils on the server. Furthermore, only the mount.nfs command from 
+    nfs-utils-1.1.1 is needed on the client.
+
+  - Install a Linux kernel with NFS/RDMA
+
+    The NFS/RDMA client and server are both included in the mainline Linux 
+    kernel version 2.6.25 and later. This and other versions of the 2.6 Linux 
+    kernel can be found at:
+
+    ftp://ftp.kernel.org/pub/linux/kernel/v2.6/
+
+    Download the sources and place them in an appropriate location. 
+
+  - Configure the RDMA stack
+
+    Make sure your kernel configuration has RDMA support enabled. Under
+    Device Drivers -> InfiniBand support, update the kernel configuration  
+    to enable InfiniBand support [NOTE: the option name is misleading. Enabling
+    InfiniBand support is required for all RDMA devices (IB, iWARP, etc.)]. 
+    
+    Enable the appropriate IB HCA support (mlx4, mthca, ehca, ipath, etc.) or 
+    iWARP adapter support (amso, cxgb3, etc.).
+
+    If you are using InfiniBand, be sure to enable IP-over-InfiniBand support.
+
+  - Configure the NFS client and server
+
+    Your kernel configuration must also have NFS file system support and/or 
+    NFS server support enabled. These and other NFS related configuration 
+    options can be found under File Systems -> Network File Systems.
+
+  - Build, install, reboot
+
+    The NFS/RDMA code will be enabled automatically if NFS and RDMA
+    are turned on. The NFS/RDMA client and server are configured via the hidden
+    SUNRPC_XPRT_RDMA config option that depends on SUNRPC and INFINIBAND. The 
+    value of SUNRPC_XPRT_RDMA will be:
+
+     - N if either SUNRPC or INFINIBAND are N, in this case the NFS/RDMA client 
+       and server will not be built
+     - M if both SUNRPC and INFINIBAND are on (M or Y) and at least one is M,
+       in this case the NFS/RDMA client and server will be built as modules
+     - Y if both SUNRPC and INFINIBAND are Y, in this case the NFS/RDMA client 
+       and server will be built into the kernel
+
+    Therefore, if you have followed the steps above and turned no NFS and RDMA,
+    the NFS/RDMA client and server will be built.
+
+    Build a new kernel, install it, boot it.
+
+Check RDMA and NFS Setup
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+    Before configuring the NFS/RDMA software, it is a good idea to test 
+    your new kernel to ensure that the kernel is working correctly.
+    In particular, it is a good idea to verify that the RDMA stack 
+    is functioning as expected and standard NFS over TCP/IP and/or UDP/IP 
+    is working properly.
+
+  - Check RDMA Setup
+
+    If you built the RDMA components as modules, load them at
+    this time. For example, if you are using a Mellanox Tavor/Sinai/Arbel 
+    card:
+    
+    > modprobe ib_mthca
+    > modprobe ib_ipoib
+
+    If you are using InfiniBand, make sure there is a Subnet Manager (SM)
+    running on the network. If your IB switch has an embedded SM, you can
+    use it. Otherwise, you will need to run an SM, such as OpenSM, on one
+    of your end nodes.
+
+    If an SM is running on your network, you should see the following:
+
+    > cat /sys/class/infiniband/driverX/ports/1/state 
+    4: ACTIVE
+
+    where driverX is mthca0, ipath5, ehca3, etc.
+
+    To further test the InfiniBand software stack, use IPoIB (this
+    assumes you have two IB hosts named host1 and host2):
+
+    host1> ifconfig ib0 a.b.c.x 
+    host2> ifconfig ib0 a.b.c.y
+    host1> ping a.b.c.y
+    host2> ping a.b.c.x
+    
+    For other device types, follow the appropriate procedures.
+
+  - Check NFS Setup
+
+    For the NFS components enabled above (client and/or server), 
+    test their functionality over standard Ethernet using TCP/IP or UDP/IP.
+
+NFS/RDMA Setup
+~~~~~~~~~~~~~~
+
+  We recommend that you use two machines, one to act as the client and 
+  one to act as the server. 
+
+  One time configuration:
+
+  - On the server system, configure the /etc/exports file and 
+    start the NFS/RDMA server.
+
+    Exports entries with the following format have been tested:
+
+    /vol0   10.97.103.47(rw,async) 192.168.0.47(rw,async,insecure,no_root_squash)
+
+    Here the first IP address is the client's Ethernet address and the second 
+    IP address is the clients IPoIB address.
+
+ Each time a machine boots:
+
+  - Load and configure the RDMA drivers
+   
+    For InfiniBand using a Mellanox adapter: 
+
+    > modprobe ib_mthca
+    > modprobe ib_ipoib
+    > ifconfig ib0 a.b.c.d  
+    
+    NOTE: use unique addresses for the client and server
+
+  - Start the NFS server
+
+    If the NFS/RDMA server was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in kernel config), 
+    load the RDMA transport module:
+
+    > modprobe svcrdma
+
+    Regardless of how the server was built (module or built-in), start the server:
+
+    > /etc/init.d/nfs start
+
+    or 
+
+    > service nfs start
+
+    Instruct the server to listen on the RDMA transport:
+
+    > echo rdma 2050 > /proc/fs/nfsd/portlist
+
+  - On the client system
+
+    If the NFS/RDMA client was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in kernel config),
+    load the RDMA client module:
+
+    > modprobe xprtrdma.ko 
+
+    Regardless of how the client was built (module or built-in), issue the mount.nfs command:
+
+    > /path/to/your/mount.nfs <IPoIB-server-name-or-address>:/<export> /mnt -i -o rdma,port=2050
+
+    To verify that the mount is using RDMA, run "cat /proc/mounts" and check the 
+    "proto" field for the given mount.
+
+  Congratulations! You're using NFS/RDMA!

This seems a little odd in the context of instructions on how to use
the code in the kernel.  Maybe something like:

 - Install an RDMA device

   Any device supported by the drivers in drivers/infiniband/hw is
   acceptable.

 - R.
