2 Setting up NFS/RDMA
14 This document describes how to install and setup the Linux NFS/RDMA client
17 The NFS/RDMA client was first included in Linux 2.6.24. The NFS/RDMA server
35 use with NFS/RDMA.
46   The first kernel release to contain both the NFS/RDMA client and server was
55   An NFS/RDMA mount point can be obtained by using the mount.nfs command in
57   version with support for NFS/RDMA mounts, but for various reasons we
73   these to create an NFS/RDMA enabled mount command), the installation
85   the utils/mount directory. This binary can be used to initiate NFS v2, v3,
96   In this location, mount.nfs will be invoked automatically for NFS mounts
101       on the NFS client machine. You do not need this specific version of
105 - Install a Linux kernel with NFS/RDMA
107   The NFS/RDMA client and server are both included in the mainline Linux
125 - Configure the NFS client and server
127   Your kernel configuration must also have NFS file system support and/or
128   NFS server support enabled. These and other NFS related configuration
133   The NFS/RDMA code will be enabled automatically if NFS and RDMA
134   are turned on. The NFS/RDMA client and server are configured via the hidden
138     #. N if either SUNRPC or INFINIBAND are N, in this case the NFS/RDMA client
142        in this case the NFS/RDMA client and server will be built as modules
144     #. Y if both SUNRPC and INFINIBAND are Y, in this case the NFS/RDMA client
147   Therefore, if you have followed the steps above and turned no NFS and RDMA,
148   the NFS/RDMA client and server will be built.
152 Check RDMA and NFS Setup
155 Before configuring the NFS/RDMA software, it is a good idea to test
158 is functioning as expected and standard NFS over TCP/IP and/or UDP/IP
200 - Check NFS Setup
202   For the NFS components enabled above (client and/or server),
205 NFS/RDMA Setup
214 - On the server system, configure the /etc/exports file and start the NFS/RDMA server.
225     The "insecure" option must be used because the NFS/RDMA client does
245 - Start the NFS server
247   If the NFS/RDMA server was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in
275   If the NFS/RDMA client was built as a module (CONFIG_SUNRPC_XPRT_RDMA=m in
283   command to mount the NFS/RDMA server:
292   Congratulations! You're using NFS/RDMA!
