# Configure Data Optimizer volumes to restart automatically

After you complete the **Add Service** wizard, you can configure Data Optimizer volumes to automatically start when the data nodes are rebooted.

**Note:** If **Auto Start** is enabled for the HDFS Datanode component, then this configuration change is required.

1. In the Cloudera dashboard, navigate to **Cluster Admin** > **Service** > **Auto Start** > **Pentaho Data Optimizer**
2. Locate the **Auto Start** status for the Data Optimizer volume component and change it to **Enabled**.
3. Save your changes.

The Data Optimizer volumes start automatically when the data nodes are rebooted.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdc-10.2-data-optimizer/pdso-install-landing-page/pdso-install-in-hadoop-cluster/pdso-install-landing-page-hadoop-installation/installing-data-storage-optimizer-on-cloudera-manager-cluster-cp/configure-data-storage-optimizer-volumes-to-auto-restart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
