Chapter 5. Configuring Red Hat Cluster With system-config-
cluster
This chapter describes how to configure Red Hat Cluster software using system -config-cluster,
and consists of the following sections:
Section 5.1, “Configuration T asks”
Section 5.2, “Starting the Cluster Configurat ion T ool”
Section 5.3, “Configuring Cluster Properties”
Section 5.4, “Configuring Fence Devices”
Section 5.5, “Adding and Deleting Members”
Section 5.6, “Configuring a Failover Domain”
Section 5.7, “Adding Cluster Resources”
Section 5.8, “Adding a Cluster Service to the Cluster”
Section 5.9, “Propagating T he Configuration File: New Cluster”
Section 5.10, “Starting the Cluster Software”
Note
While system -config-cluster provides several convenient tools for configuring and
managing a Red Hat Cluster, the newer, more comprehensive tool, Conga, provides more
convenience and flexibility than system -config-cluster. You may want to consider using
Conga instead (refer to Chapter 3, Configuring Red Hat Cluster With Conga and Chapter 4,
Managing Red Hat Cluster With Conga).
5.1. Configuration Tasks
Configuring Red Hat Cluster software with system-config-cluster consists of the following steps:
1. Starting the Cluster Configuration Tool, system-config-cluster. Refer to Section 5.2,
“Starting the Cluster Configurat ion Tool”.
2. Configuring cluster properties. Refer to Section 5.3, “Configuring Cluster Properties”.
3. Creating fence devices. Refer to Section 5.4, “Configuring Fence Devices”.
4. Creating cluster members. Refer to Section 5.5, “Adding and Deleting Members”.
5. Creating failover domains. Refer to Section 5.6, “Configuring a Failover Domain”.
6. Creating resources. Refer to Section 5.7, “Adding Cluster Resources”.
7. Creating cluster services.
Refer to Section 5.8, “Adding a Cluster Service to the Cluster”.
8. Propagating the configuration file to the other nodes in the cluster.
Refer to Section 5.9, “Propagating The Configuration File: New Cluster”.
9. Starting the cluster software. Refer to Section 5.10, “Starting the Cluster Software”.
5.2. Starting the Cluster Configuration Tool
You can start the Cluster Configuration Tool by logging in to a cluster node as root with the ssh -Y
command and issuing the system-config-cluster command. For example, to start the Cluster
