- <para>To see the steps in a simple Lustre configuration, follow this example in which a combined MGS/MDT and two OSTs are created. Three block devices are used, one for the combined MGS/MDS node and one for each OSS node. Common parameters used in the example are listed below, along with individual node parameters.</para>
