Kubernetes - PersistentVolumeClaim failed - kubernetes

Question

I have a GKE based Kubernetes setup and a POD that requires a storage volume. I attempt to use the config below:
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: my-scratch-space
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2000Gi
storageClassName: standard
This PVC is not provisioned. I get the below error:
Failed to provision volume with StorageClass "standard": googleapi: Error 503: The zone 'projects/p01/zones/europe-west2-b' does not have enough resources available to fulfill the request. Try a different zone, or try again later.
Looking at GKE quotas page, I don't see any issues. Deleting other PVCs also is not solving the issue. Can anyone help? Thanks.

Answer 1

There is no configuration problem at your side - there are actually not enough resources in the europe-west2-b zone to create a 2T persistent disk. Either try for a smaller volume or use a different zone.
There is an example for GCE in the docs. Create a new StorageClass specifying say the europe-west1-b zone (which is actually cheaper than europe-west2-b) like this:
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: gce-pd-europe-west1-b
provisioner: kubernetes.io/gce-pd
parameters:
type: pd-standard
zones: europe-west1-b
And modify your PVC:
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: my-scratch-space
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2000Gi
storageClassName: gce-pd-europe-west1-b
