In the previous chapter, you learned how to add, manage, and remove failover domains, cluster resources, and cluster services with RGManager on CentOS 6. Since a computer cluster is a live system and is constantly developing and growing with additional resources and services, it is also very important for you, as a cluster administrator, to know how to add or remove a cluster node from the cluster if the situation requires you to.

This chapter focuses on familiarizing you with cluster node management on CentOS 6. You will learn how to add and remove cluster nodes from an existing and running computer cluster.
