Briefly, this error occurs when OpenSearch is unable to mark a data store as corrupted due to insufficient permissions or a locked file. This could be due to the OpenSearch process not having the necessary permissions to modify the store files, or another process may be using the files, preventing OpenSearch from accessing them. To resolve this issue, ensure that the OpenSearch process has the correct permissions to modify the store files. If the files are locked by another process, identify and stop that process. Alternatively, you may need to restart the OpenSearch service.
