Chapter 20

Introducing High-Availability Clustering

Topics covered in this chapter:

Understanding High-Availability Clustering
Configuring Cluster-Based Services
Installing the Red Hat High Availability Add-on
Creating Resources and Services
Configuring GFS2 File Systems

High-availability clustering is often used in conjunction with Red Hat Enterprise Linux. In this chapter, you'll learn how to set up a high-availability cluster using the Red Hat High Availability add-on. Using such a cluster lets you guarantee that vital services are available at all times and, if something bad happens to your servers, that the services monitored by high availability are restarted on another node as soon as possible.
