Red Hat CLUSTER SUITE FOR ENTERPRISE LINUX 5.2 Overview page 22

Chapter 1. Red Hat Cluster Suite Overview
The Cluster Configuration System (CCS) manages the cluster configuration and provides
configuration information to other cluster components in a Red Hat cluster. CCS runs in each
cluster node and makes sure that the cluster configuration file in each cluster node is up to date.
For example, if a cluster system administrator updates the configuration file in Node A, CCS
propagates the update from Node A to the other nodes in the cluster (refer to Figure 1.7, "CCS
Overview").
Figure 1.7. CCS Overview
Other cluster components (for example, CMAN) access configuration information from the
configuration file through CCS (refer to Figure 1.7, "CCS Overview").
