1.1. The Scope of this Document

The purpose of this document is to help system administrators learn how to manage a Pacemaker cluster.
System administrators may be interested in other parts of the Pacemaker documentation set, such as Clusters from Scratch, a step-by-step guide to setting up an example cluster, and Pacemaker Explained, an exhaustive reference for cluster configuration.
Multiple higher-level tools (both command-line and GUI) are available to simplify cluster management. However, this document focuses on the lower-level command-line tools that come with Pacemaker itself. The concepts are applicable to the higher-level tools, though the syntax would differ.
