3 Configuring a Test Cluster and Service

This chapter provides step-by-step instructions on configuring a test cluster across two nodes that are hosted on systems with the resolvable host names node1 and node2. Each system is installed and configured by using the instructions that are provided in Installing and Configuring Pacemaker and Corosync.

The test cluster is configured to run a service, Dummy, that is included in the resource-agents package for testing purposes. The Dummy resource agent keeps track of whether the service is or is not running.

To demonstrate a successful failover, the cluster service is stopped on the node the Dummy service is initially running on, and the pcs status command is used to confirm the service has successfully started on the other node that is still on line.
