Chapter 6. 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:

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).

6.1. 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
  3. service clvmd stop, if CLVM has been used to create clustered volumes
  4. service cman stop
Stopping the cluster services on a member causes its services to fail over to an active member.
