Chapter 8. The Cluster Configuration File

Configuring a cluster with Conga modifies the cluster configuration file. This chapter shows the cluster configuration file before and after the procedures documented in Chapter 4, Configuring the Cluster Resources and Chapter 5, Configuring an NFS Cluster Service were performed.

Before the cluster resources and service were configured, the cluster.conf file appeared as follows.
