Hi,

I'm getting the error Unable to mount volumes for pod error from the sample-prometheus-instance.yaml. No change was made in the yaml file.

Was wondering anyone encounters the same error?

https://github.com/luxas/kubeadm-workshop/blob/master/demos/monitoring/sample-prometheus-instance.yaml

   Unable to mount volumes for pod "prometheus-sample-metrics-prom-0_default(469b4880-0a9b-11e8-a29b-0800272637bb)": timeout expired waiting for volumes to attach/mount for pod "default"/"prometheus-sample-metrics-prom-0". list of unattached/unmounted volumes=[prometheus-sample-metrics-prom-db]
