pod failed to use pvc with standard-rwx storageclass

[oliv]

As described in google doc I enable the filestore csi driver in my cluster. It created automatically

differents storageclass.

kubectl get sc                     
NAME                        PROVISIONER                    RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE

enterprise-rwx              filestore.csi.storage.gke.io   Delete          WaitForFirstConsumer   true                   2d10h

premium-rwx                 filestore.csi.storage.gke.io   Delete          WaitForFirstConsumer   true                   2d10h

standard-rwo (default)      pd.csi.storage.gke.io          Delete          WaitForFirstConsumer   true                   59d
standard-rwx                filestore.csi.storage.gke.io   Delete          WaitForFirstConsumer   true                   2d10h
zonal-rwx                   filestore.csi.storage.gke.io   Delete          WaitForFirstConsumer   true                   2d10h

I use one of this storageclass: standard-rwx to create a PVC 

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nwapi-uploads
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: standard-rwx
  resources:
    requests:
      storage: 10Gi

Then I create a pod who need this PVC

I see that a PV is created

NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                 STORAGECLASS   VOLUMEATTRIBUTESCLASS   REASON   AGE

but the pod is not able to use it I've got this event :

Events:
  Type     Reason       Age                    From     Message
  ----     ------       ----                   ----     -------
  Warning  FailedMount  92s (x110 over 7h19m)  kubelet  MountVolume.MountDevice failed for volume "pvc-a02dcb94-0867-4dc1-aa09-b92108e66a63" : rpc error: code = DeadlineExceeded desc = context deadline exceeded

I don't see any in logs that can explain this issue.

Even If I delete the pod and recreate it the result is the same.

Does some one has already use standard-rwx and solve this kind of trouble or have any idea about this topic?

We found the solution, the storageclass created by enabling the filestoredriver is incomplete it doesn't a mandatory parameter if you don't use the default network.

so on you have to create your own storageclass like this:

allowVolumeExpansion: true
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    components.gke.io/component-name: filestorecsi
    components.gke.io/component-version: 0.12.22
    components.gke.io/layer: addon
  labels:
    addonmanager.kubernetes.io/mode: EnsureExists
    k8s-app: gcp-filestore-csi-driver
  name: standard-rwx-my-storageclass.  #<======= change it 
parameters:
  tier: standard
  network: your-network #<=========== change it for your own network name
provisioner: filestore.csi.storage.gke.io
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer

U need to enable the filestore API "Cloud Filestore API".

"

No the solution was on network parameter that need to be added to the storageclass definition. It works without Cloud Filestore API
