# Image Cache Space

**Summary**: There is likely not enough space on the Ironic conductor node to stage images for provisioning.

**Consequences**: When using "direct" deploy mode, Ironic conductor moves disk images to a temporary disk cache before transferring it to the target node via iSCSI. When there is not enough space in this directory, the conductor will raise an error to the user when they try to provision a node. Typically this happens for users with large disk images.

#### Possible causes

Disk utilization issues usually require freeing up space somehow:

* **Resize LVM volumes**: it may be possible to simply allocate more space from a pool
* **Delete log files**: perhaps logrotate is misconfigured, or logs are simply being held for too long / are too big. Maybe a service is writing a lot of data to logs.
* **Clean Docker cache**: Docker's internal disk cache can get bloated after a while. Consider using `docker system prune` to clean out old/unused images and containers. Make sure you don't delete a stopped container that has data that you need!

## 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://chameleoncloud.gitbook.io/chi-in-a-box/operations/runbooks/ironiclowimagecachespace.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.
