This page describes how to configure and use Pacemaker with Lustre Failover.
Setting Up Cluster Communications
Communication between the nodes of the cluster allows all nodes to “see” each other. In modern clusters, OpenAIS, or more specifically, its communication stack corosync, is used for this task. All communication paths in the cluster should be redundant so that a failure of a single path is not fatal for the cluster.
An introduction to the setup, configuration and operation of a Pacemaker cluster can be found in:

Setting Up the corosync Communication Stack
The corosync communication stack, developed as part of the OpenAIS project, supports all the communication needs of the cluster. The package is included in all recent Linux distributions. If it is not included in your distribution, you can find precompiled binaries at www.clusterlabs.org/rpm. It is also possible to compile OpenAIS from source and install it on all HA nodes by running /configure; make and make install.
Note: If corosync is not included in your distribution, your distribution may include the complete OpenAIS package. From the cluster point of view, the only difference is that all files and commands start with openais rather than corosync. The configuration file is located in /etc/ais/openais.conf.
Once installed, the software looks for a configuration in the file /etc/corosync/corosync.conf.
Complete the following steps to set up the corosync communication stack:
