# Uninstall Since you may wish to have access to your data after spinning down your cluster, Cortex's bucket, stackdriver logs, and Prometheus volume are not automatically deleted when running `cortex cluster-gcp down`. ```bash cortex cluster-gcp down ``` The `cortex cluster-gcp down` command doesn't wait for the cluster to spin down. You can ensure that the cluster has spun down by checking the GKE console. ## Delete Volumes The volumes used by Cortex's Prometheus and Grafana instances are not deleted by default, as they might contain important information. If these volumes are not required anymore, you can delete them in the GCP console. Navigate to the [Disks](https://console.cloud.google.com/compute/disks) page (be sure to set the appropriate project), select the volumes, and click "Delete". The Prometheus and Grafana volumes that Cortex created have a name that starts with `gke--`, and the `kubernetes.io/created-for/pvc/name` tag starts with `prometheus-` and `grafana-` respectively. --- # Agent Instructions: 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.
