Does the Kubernetes do-block-storage StorageClass support volume expansion?

Just hit this problem as well. To help others on this issue, what you are saying is this will not work:

{
  "kind": "StorageClass",
  "apiVersion": "storage.k8s.io/v1",
  "metadata": {
    "name": "do-block-storage",
   [...]
  },
  "provisioner": "dobs.csi.digitalocean.com",
  "reclaimPolicy": "Delete",
  "volumeBindingMode": "Immediate",
  "allowVolumeExpansion": true     <== What you are saying is this will not work
}

I was able to increase the Droplets storage, and increase the PersistentVolume: spec/capacity/storage but not able to increase the PersistentVolumeClaim: spec/resources/storage. It produced the error:

"persistentvolumeclaims "[redacted]" is forbidden: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize". 

This is because, as you said, allowVolumeExpansion, is not supported.

Other than reinstalling a new Kubernetes cluster (no snowflakes here) with new and larger storage, is there a workaround or suggested alternatives?

DOKS version 1.16.2-do.3 and later supports volume expansion / resizing:

Hey friend,

Sorry for the delay on this. This feature is not currently supported on our side.

This would be useful. Is it supported?
