Conga and clusters: Building a new cluster

When building a new cluster with Conga, the nodes have to meet some of the same requirements as nodes of an existing cluster that is being administered by Conga. For example, all of the nodes must be running the ricci agent software, must be reachable, and must be able to authenticate via the root password. If some of nodes that you want to configure to be in your new cluster are unreachable, however, you can create the cluster without them and add them to the cluster later when they are available.

The first step in creating the new cluster is to define the cluster’s name and select the nodes that will comprise the cluster. To do this, you select “Create a New Cluster” from the cluster tab and fill in this form:

The options listed in this form are:

Download packages from Red Hat Network® – If you select this option, when Conga creates the cluster all the packages necessary to support the cluster (rgmanager, cman, etc.) are automatically downloaded and installed. This is a helpful feature in that the cluster nodes will have the most recent version of the packages you install. Using this option also ensures that all the cluster nodes are running the same version of the cluster packages.
