Error expanding PVC in OpenShift ARO

[mcipamo]

Hi there,

Describe the problem: Customer cannot expand PVC size on ARO cluster using Netapp storage, getting an error:

Ignoring the PVC: didn't find a plugin capable of expanding the volume; waiting for an external controller to process this PVC.

Confirmed that the StorageClass has the allowVolumeExpansion flag set to true.

OpenShift Version: 4.13.23

Is there any additional requirement or specific setup needed for the Trident CSI driver, to enable volume expansion in the ARO environment?

Thanks for your assistance

Can you please provide additional details of the PVC, PV and storage class, e.g.

oc get pvc <pvc-name> -o yaml

oc get pv <pv name> -o yaml <-- PV Name will be listed in previous output as volumeName

oc get sc <storage class name> -o yaml
