<p>I applied my PVC yaml file to my GKE cluster and checked it's state.
It says the follwing for the yaml:</p>

<pre><code>apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"v1","kind":"PersistentVolumeClaim","metadata":{"annotations":{},"name":"teamcity","namespace":"default"},"spec":{"accessModes":["ReadWriteMany"],"resources":{"requests":{"storage":"3Gi"}}}}
    volume.beta.kubernetes.io/storage-provisioner: kubernetes.io/gce-pd
  creationTimestamp: "2019-11-05T09:45:20Z"
  finalizers:
  - kubernetes.io/pvc-protection
  name: teamcity
  namespace: default
  resourceVersion: "1358093"
  selfLink: /api/v1/namespaces/default/persistentvolumeclaims/teamcity
  uid: fb51d295-ffb0-11e9-af7d-42010a8400aa
spec:
  accessModes:
  - ReadWriteMany
  dataSource: null
  resources:
    requests:
      storage: 3Gi
  storageClassName: standard
  volumeMode: Filesystem
status:
  phase: Pending
</code></pre>

<p>I did not created anything like a storage or whatever needs to be done for that? Because I read it as this is provided automatically by the GKE. Any idea what I am missing?</p>

<p>GKE includes default support for GCP disk PV provisioning, however those implement ReadWriteOnce and ReadOnlyMany modes. I do not think GKE includes a provisioner for ReadWriteMany by default.</p>

<p>EDIT: While it's not set up by default (because it requires further configuration) <a href="https://stackoverflow.com/questions/54796639/how-do-i-create-a-persistent-volume-claim-with-readwritemany-in-gke">How do I create a persistent volume claim with ReadWriteMany in GKE?</a> shows how to use Cloud Filestore to launch a hosted NFS-compatible server and then aim a provisioner at it.</p>
