Managing Red Hat Cluster With

system-config-cluster

This chapter describes various administrative tasks for managing a Red Hat Cluster and

consists of the following sections:

• Section 1, “Starting and Stopping the Cluster Software”

• Section 2, “Managing High-Availability Services”

• Section 4, “Backing Up and Restoring the Cluster Database”

• Section 5, “Disabling the Cluster Software”

• Section 6, “Diagnosing and Correcting Problems in a Cluster”

Tip

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).

1. Starting and Stopping the Cluster Software

To start the cluster software on a member, type the following commands in this order:

1. service cman start

2. service clvmd start, if CLVM has been used to create clustered volumes

3. service gfs start, if you are using Red Hat GFS

4. service rgmanager start

To stop the cluster software on a member, type the following commands in this order:

1. service rgmanager stop

2. service gfs stop, if you are using Red Hat GFS
