ECK 1.0 with on premise K8s

Elastic Orchestration Elastic Cloud on Kubernetes (ECK)
1

Hi,
I have installed a basic k8s cluster with kubeadm; cluster node state is ready and I can deploy an nginx image.. so far so good.

Next I installed the elastic operator (1.0.0-beta1) using the steps described on: https://www.elastic.co/downloads/elastic-cloud-kubernetes

The operator seems to install fine and I can launch a kibana instance. However elasticsearch pods remain in pending state and the error message I get is:
pod has unbound immediate PersistentVolumeClaims

If i type kubectl describe pvc elastic i get:
no persistent volumes available for this claim and no storage class is set

I tried creating a pv but with no success. Does anybody have an idea what I am doing wrong?

Solved it:

The storageClassName: directive was not consistent. Both in the pv declaration as the elastic quickstart yaml it needed to be set.

Here is my elastic yaml file, maybe it helps other newbies:
