orangefs: document package install and xfstests procedure
Unless one is working on the userspace code, there's no need to compile OrangeFS. The package works just fine. (But leave the documentation for building from source since not everyone uses distributions which include the package.) Also document the process to run xfstests against OrangeFS.

BUILDING THE USERSPACE FILESYSTEM ON A SINGLE SERVER

You can omit --prefix if you don't care that things are sprinkled around in

||||
/usr/local. As of version 2.9.6, Orangefs uses Berkeley DB by default, we
|
||||
will probably be changing the default to lmdb soon.
|
||||
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
|
||||
point.
|
||||
|
||||
systemctl start orangefs-client
|
||||
|
||||
Mount the filesystem.

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
|
||||
|
||||
Then xfstests can be run
|
||||
|
||||
./check -pvfs2
