Rasa X version 0.33.0 or higher is only compatible with Rasa Open Source 2.x. If you are on Rasa Open Source 1.x, please check the [compatibility matrix](https://legacy-docs-rasa-x.rasa.com/docs/rasa-x/changelog/compatibility-matrix) for a compatible version.

Rasa X itself requires only one volume claim, which is used to store trained models and a local clone of the remote Git repository.

If you are using the default Postgres instance started by the Rasa X Helm chart, then there is an additional volume claim for the database.

## Specifying Volume Sizes

You can define the claim sizes by setting the `size` of these services in your override file:

```yaml
rasax:
  persistence:
    size: "10Gi"

postgresql:
  persistence:
    size: "100Gi"
```
