The next step is to propagate the config on the nodes (compute-00-00, compute-00-01, compute-00-02). The installer is not part of the server pool (will copy the fs-conf file on clients only later).

We want a rc script to start the server, so just edit the one provided in the example directory:

--------------------------------------------------------
cp examples/pvfs2-server.rc examples/pvfs2-server
--------------------------------------------------------...

Let's play with PVFS (Parallel Virtual File System), and perform a manual install on an OCS 5 cluster. If we want to build a kit, then we should be able to recompile the code (+dependencies), understand the configuration, and of course how to test it, right ?

Two versions of are available; I will use version 2. The homepage is here:

Parallel Virtual File System, Version 2


So, let's start with the latest and greatest version: PVFS-2.7.1
...

When submitting an openmpi job through lava on a cluster that is IB enabled (OFED), you will probably see this kind of error:
