Volume expansion - Githubissues

I pushed a canary image to docker hub

I created an lke cluster

I applied this manifest:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-test
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: linode-block-storage
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: /testmount
          name: pvc-test
      volumes:
      - name: pvc-test
        persistentVolumeClaim:
          claimName: pvc-test

I ran kubectl apply -f ./e2e/test/manifest/linode-blockstorage-csi-driver.yaml (the manifest generated in this repo that is pointed at the canary image)

I ran kubectl edit pvc and changed the spec's storage to 11gb (from 10)

I now see 11gb in cloud manager.

kubectl describe pvc now shows 11gb

I pushed a canary image to docker hub

I created an lke cluster with two nodes

I applied this manifest:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-test
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: linode-block-storage

      volumes:
      - name: pvc-test
        persistentVolumeClaim:
          claimName: pvc-test

I ran kubectl edit pvc and changed the spec's storage to 11gb (from 10)

Saw error

error: persistentvolumeclaims "pvc-test" could not be patched: persistentvolumeclaims "pvc-test" is forbidden: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize

I ran kubectl apply -f ./e2e/test/manifest/linode-blockstorage-csi-driver.yaml (the manifest generated in this repo that is pointed at the canary image)

I ran kubectl edit pvc and changed the spec's storage to 11gb (from 10), and it was successful.

I now see 11gb in cloud manager.

kubectl describe pvc now shows 11gb
