Remove a Worker Node from a VMware Aria Operations for Logs Cluster

You can remove a worker node that is no longer working correctly from a VMware Aria Operations for Logs cluster. Do not remove worker nodes that are operating correctly from a cluster.

Warning: Removing a node results in data loss. If a node must be removed, ensure that it has been backed up first. Avoid removing nodes within 30 minutes of adding new nodes.

Prerequisites

Verify that you are logged in to the VMware Aria Operations for Logs web user interface as a Super Admin user, or a user associated with a role that has the relevant permissions. See Create and Modify Roles for more information. The URL format of the web user interface is https://operations-for-logs-host, where operations-for-logs-host is the IP address or host name of the VMware Aria Operations for Logs virtual appliance.

Procedure

1. Expand the main menu and navigate to Management > Cluster.
2. In the Workers table, find the node you want, click the pause icon, and click Continue.
   The node is now in maintenance mode.

   Note: A node in maintenance mode continues to receive logs.
3. Click the cross icon to remove the node.
   VMware Aria Operations for Logs removes the node from the cluster and sends out an email notification.
