+OrangeFS is usually run in large installations with multiple servers and
+clients, but a complete filesystem can be run on a single machine for
+development and testing.
+
+On Fedora, install orangefs and orangefs-server.
+
+dnf -y install orangefs orangefs-server
+
+There is an example server configuration file in
+/etc/orangefs/orangefs.conf. Change localhost to your hostname if
+necessary.
+
+To generate a filesystem to run xfstests against, see below.
+
+There is an example client configuration file in /etc/pvfs2tab. It is a
+single line. Uncomment it and change the hostname if necessary. This
+controls clients which use libpvfs2. This does not control the
+pvfs2-client-core.
+
+Create the filesystem.
+
+pvfs2-server -f /etc/orangefs/orangefs.conf
+
+Start the server.
+
+systemctl start orangefs-server
+
+Test the server.
+
+pvfs2-ping -m /pvfsmnt

+Start the client. The module must be compiled in or loaded before this

+RUNNING XFSTESTS
+================
+
+It is useful to use a scratch filesystem with xfstests. This can be
+done with only one server.
+
+Make a second copy of the FileSystem section in the server configuration
+file, which is /etc/orangefs/orangefs.conf. Change the Name to scratch.
+Change the ID to something other than the ID of the first FileSystem
+section (2 is usually a good choice).
+
+Then there are two FileSystem sections: orangefs and scratch.
+
+This change should be made before creating the filesystem.
+
+pvfs2-server -f /etc/orangefs/orangefs.conf
+
+To run xfstests, create /etc/xfsqa.config.
+
+TEST_DIR=/orangefs
+TEST_DEV=tcp://localhost:3334/orangefs
+SCRATCH_MNT=/scratch
+SCRATCH_DEV=tcp://localhost:3334/scratch
