Installing and Using Lustre with OpenSSI

The OpenSSI support for Lustre currently extends to enabling 
OpenSSI nodes to act as Lustre clients. This means that nodes
within a SSI cluster can mount a Lustre file through a remote 
Lustre server that is external to the cluster.
Each node performs the mount locally. So, if individual nodes
need access to the Lustre filesystem, they need to mount it

Getting it to work.
Here are the steps to enable Lustre on OpenSSI.
1. Download and install the OpenSSI 1.1.1 release from The website has detailed instructions
   on how to install OpenSSI.
   This kernel already includes the Lustre patches for a given 
   version of Lustre. The currently supported  version is 1.0.4.
2. Boot up with the new OpenSSI kernel. Add new nodes if any.

Now that you have the OpenSSI cluster up and running, here are the 
remaining steps:
3. Install the lustre-ssi RPMs.
   Make sure you install at least the lustre-modules and lustre-lite
   RPMs. These contain the kernel modules and Lustre utilities 
   such as lconf respectively.
   Note: The Lustre RPMs in lustre-fc2-1.1.1.i686.tar assume that you have 
   installed the kernel-ssi RPM from the 1.1.1 release and thus the 
   lustre_modules RPM installs the modules in 
4. Once the installation is complete, you can use 
   your existing configuration files with lconf just the way
   you were using it on rh9.  

1. If you need to play around with the Lustre source, make sure you download
   the OpenSSI source tree for OpenSSI-1.1.1 since you will require that for 
   compiling the Lustre source tree.
   If you do that, the installation procedure for Lustre is pretty much the 
   same as on the base. Make and install the Lustre package.
