This chapter shows how to configure a simple Lustre file system comprised of a combined MGS/MDT, an OST and a client. However, the administrative utilities provided with Lustre can be used to set up a systems with many different configurations.

Note: We recommend that you use dotted-quad (dot-decimal) notation for IP addresses (IPv4) rather than host names. This aids in reading debug logs and helps when debugging configurations with multiple interfaces.

Configuring the Lustre File System

Complete these steps to configure Lustre Networking (LNET) and the Lustre file system:

1. Define the module options for Lustre networking (LNET), by adding this line to the /etc/modprobe.conf file. The modprobe.conf file is a Linux file that specifies which parts of the kernel are loaded.

options lnet networks=<network interfaces that LNET can use>

This step restricts LNET to using only the specified network interfaces and prevents LNET from using all network interfaces.

As an alternative to modifying the modprobe.conf file, you can modify the modprobe.local file or the configuration files in the modprobe.d directory. Note: For details on configuring networking and LNET, see the Configuring LNET section in the Lustre Operations Manual.
