I'm trying to set up a mongodb replicaset using this guide: https://kubernetes.io/blog/2017/01/running-mongodb-on-kubernetes-with-statefulsets/ I want my data to be stored locally for the replicaset following https://kubernetes.io/blog/2018/04/13/local-persistent-volumes-beta/.

The pod status stays PENDING because of the following event:

Normal     FailedBinding  3m47s (x723 over 3h3m)  persistentvolume-controller  no persistent volumes available for this claim and no storage class is set

However I declared my storage class and persistent volumes (unlike no persistent volumes available for this claim and no storage class is set).

Here is the deployment file:
