Starting and Stopping a Cluster

Starting a cluster would mean starting all the nodes of a cluster. Similarly, stopping a cluster would mean stopping all the nodes of a cluster.

You start or stop a node by starting or stopping the OpenSearch service on each node.

Important:

Before you stop a node, you should ensure that no indexing requests or administration-related tasks are being made on the cluster. If you stop a node during indexing, the cluster meta data might get corrupted and the cluster could become non-operational (red color code). To ensure that no instances of PTSF_GENFEED are running, check the Process Monitor. If all processes are completed, you may stop all the nodes in a cluster and make the required modifications. After completing the modifications, you may start all the nodes of the cluster.
