Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which analyzes 2 JSON files to detect many errors.

Briefly, this error occurs when Elasticsearch is attempting to update a persistent setting that is not dynamically updateable. This error can occur when there is a conflict between the new setting value and an existing setting or when the setting is not designed to be updated dynamically. To resolve this error, you can check the setting’s documentation to see if it is dynamically updateable or not. If it is not, you will need to manually update the setting in the Elasticsearch configuration file or through the Elasticsearch API. If there is a conflict with an existing setting, you may need to modify the setting to resolve the conflict.

To easily locate the root cause and resolve this issue try AutoOps for Elasticsearch & OpenSearch. It diagnoses problems by analyzing hundreds of metrics collected by a lightweight agent and offers guidance for resolving them.
