7.7 Adding and Deleting client nodes

This section describes the steps need when it becomes necessary to add or delete client nodes. If you have already built your cluster successfully and would like to add or delete a client node, execute the following from the top-level OSCAR directory:

  # ./install_cluster <device>

Like before, you must substitute the device name (e.g., eth1) for the server node's internal ethernet adapter in the above command. See Section 7.2.1 (page [*]). Once the OSCAR wizard appears, you are ready to add or delete clients. Note that these steps will reuse the existing images made with the initial install, however, it will extend or contract the set of defined clients in the cluster.


7.7.1 Adding OSCAR clients

Press the button of the wizard entitled $<$Add OSCAR Clients$>$. A sample dialog is shown in Figure 6. These steps should seem familiar - they are same as steps 3, 4 and 5 of the initial install. Refer to Sections 7.3.3, 7.3.4, and 7.5.1.

Note that when adding nodes, in the Defining OSCAR Clients step (step 1), you will typically need to change the following fields to suit your particular configuration:
