Adding Additional OpenSearch Nodes

Use these steps to add an additional OpenSearch node after you have completed the OSK DPK installation. The additional node will be added to the same cluster.

1. Install OpenSearch on a second server and provide the following information during the DPK setup script:

   • For the cluster name, specify the same name as that of the first OpenSearch node.

   • At the prompt “Enter the host name of nodes which are already member of a cluster”, specify the IP address for the first OpenSearch node.

2. Stop and restart the second OpenSearch node.

   See Starting and Stopping an OpenSearch Service.

To avoid “split brain” problem, it is always recommended to have an odd number of nodes (N) in the cluster if N is less than 4. For more information, search for details about configuring minimum master nodes in the OpenSearch online help.
