Bug 2227100

Description of problem:
When using the Trident provisioner, I cannot create a VM from template using a bootsource after creating a VolumeSnapshotClass. Creating a VM works fine before creating the VolumeSnapshotClass.

If I add or set "allowVolumeExpansion: true" in the Trident storage class, it works. But there are no indications in the UI or DV status that this is the issue.


Version-Release number of selected component (if applicable):
OpenShift Virtualization 4.13.2
Trident Operator 23.04.0


How reproducible:
Consistent

Steps to Reproduce:
1.Install the Trident Operator
2.Create a storageclass for Trident without allowVolumeExpansion set to true.
~~~
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: trident-cnvi-svm
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
provisioner: csi.trident.netapp.io
reclaimPolicy: Delete
allowVolumeExpansion: true
parameters:
  backendType: "ontap-nas"
~~~

3. Create a RHEL 9 VM from template and boot source. This works fine.

4. Create a VolumeSnapshotClass for Trident.
~~~
apiVersion: snapshot.storage.k8s.io/v1
kind: VolumeSnapshotClass
metadata:
  name: trident-snapclass
driver: csi.trident.netapp.io
deletionPolicy: Delete
~~~

5. Try to create another RHEL 9 VM from template and boot source. This will never complete. The DV Phase stays in "SnapshotForSmartCloneInProgress"

The cdi-deployment pod shows log messages like such:
~~~
{"level":"error","ts":1690492689.26244,"logger":"controller.datavolume-pvc-clone-controller","msg":"Reconciler error","name":"rhel9-after-vsc","namespace":"winding","error":"persistentvolumeclaims \"cdi-tmp-1434dc2c-c012-406b-afc5-438912628dcf\" is forbidden: only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:266\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:227"}
~~~

6. Remove the StorageClass and recreate it with allowVolumeExpansion set to true
~~~
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: trident-cnvi-svm
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
provisioner: csi.trident.netapp.io
reclaimPolicy: Delete
allowVolumeExpansion: true
volumeBindingMode: Immediate
parameters:
  backendType: "ontap-nas"
~~~

7. Create a RHEL 9 VM from template and bootsource. This will now work (rather quickly).


Actual results:


Expected results:
I would expect a notification in the UI or DV that this was the issue.
