1.3. The cluster and Pacemaker configuration files
The configuration files for the Red Hat High Availability Add-On are corosync.conf and cib.xml.
-
The
corosync.conffile provides the cluster parameters used bycorosync, the cluster manager that Pacemaker is built on. In general, you should not edit thecorosync.confdirectly but, instead, use thepcsinterface, the HA Cluster Management RHEL web console add-on, or theha_clusterRHEL system role. -
The
cib.xmlfile is an XML file that represents both the cluster’s configuration and the current state of all resources in the cluster. This file is used by Pacemaker’s Cluster Information Base (CIB). The contents of the CIB are automatically kept in sync across the entire cluster. Do not edit thecib.xmlfile directly; use thepcsinterface, the HA Cluster Management RHEL web console add-on, or theha_clusterRHEL system role.
