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”).
