Removing a cluster node

Shutting down a cluster node is one way to disable it, but you must also learn how to remove a cluster node from a running cluster configuration. Removing a cluster node from a cluster configuration does not require cluster service downtime, unless the cluster service is running on the cluster node you would like to remove.

Tip

Before you start the procedure of removing a cluster node from the cluster configuration, make sure that no cluster resources and services are running on the node.

You can remove a cluster node from an existing configuration by following these steps:

1. Remove the cluster node from Corosync: Edit the corosync.conf configuration file on all cluster nodes and remove the desired cluster node from the nodelist section. You can download an example cluster node corosync.conf configuration file, where the node-4.geekpeek.net cluster node was removed from the cluster configuration, from the corosync-conf-2.txt file in the code bundle.

   Note
