# Resize a volume
***
## Resize a volume using the control panel
It's possible to resize a volume, both upward and downward. At the top of the page for the current volume, click **Actions** and then **Change plan**.
In the dialog box that appears, select a new size for the volume and then click **Update Settings**. Here, you can also enable or disable automatic upgrade of the volume.
## Resize a volume using the API
Use the [filestorage/listplans](https://github.com/GleSYS/API-docs/wiki/API-Documentation#filestoragelistplans) endpoint to list available plans, then [filestorage/editvolume](https://github.com/GleSYS/API-docs/wiki/API-Documentation#filestorageeditvolume) to change the plan, i.e., resize the volume.
For general instructions on how to use the API, see [Platform → API](/platform/control-panel/api.md).

## 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.glesys.com/products/storage/file-storage/how-tos/resize-a-volume.md?ask=&goal=
```
`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.
