3.1. Starting, Stopping, and Deleting Clusters

You can perform the following cluster-management functions through the luci server component of Conga:

To perform one of the functions in the preceding list, follow the steps in this section. The starting point of the procedure is at the cluster tab (at the Choose a cluster to administer page).

  1. At the right of the Cluster Name for each cluster listed on the Choose a cluster to administer page is a drop-down box. By default, the drop-down box is set to Restart this cluster. Clicking the drop-down box box reveals all the selections available: Restart this cluster, Stop this cluster/Start this cluster, and Delete this cluster. The actions of each function are summarized as follows:

    • Restart this cluster — Selecting this action causes the cluster to be restarted. You can select this action for any state the cluster is in.

    • Stop this cluster/Start this clusterStop this cluster is available when a cluster is running. Start this cluster is available when a cluster is stopped.

      Selecting Stop this cluster shuts down cluster software in all cluster nodes.

      Selecting Start this cluster starts cluster software.

    • Delete this cluster — Selecting this action halts a running cluster, disables cluster software from starting automatically, and removes the cluster configuration file from each node. You can select this action for any state the cluster is in. Deleting a cluster frees each node in the cluster for use in another cluster.

  2. Select one of the functions and click Go.

  3. Clicking Go causes a progress page to be displayed. When the action is complete, a page is displayed showing either of the following pages according to the action selected:

    • For Restart this cluster and Stop this cluster/Start this cluster — Displays a page with the list of nodes for the cluster.

    • For Delete this cluster — Displays the Choose a cluster to administer page in the cluster tab, showing a list of clusters.
