I'm using the PersistentVolume functionality for sharing VM directories with Pods. For example:

```
apiVersion: v1
kind: PersistentVolume
metadata:
  name: psql-data-disk
spec:
  accessModes:
    - ReadWriteOnce
  capacity:
    storage: 1Gi
  hostPath:
    path: /data/psqldata

```

But I can't figure out how to delete the directory from the host VM so that I can reset the data. Minikube persists the `/data/` directory across VM reboots, but doesn't document where it's storing it.

If you `kubectl delete PersistentVolume psql-data-disk` it doesn't delete any of the contents in the directory itself, it just deletes the K8s resource.

I'm using the `docker-machine-driver-xhyve` driver installed via brew on OSX Sierra.
