Hostpath driver fails to delete volumesnapshotcontent whose DeletionPolicy is patched to Delete

[ashish-amarnath]

What happened:
A patched volumesnapshotcontent object does not get deleted.

These are the steps that I followed:

1. Create a volumesnapshot using a volumesnapshotclass with DeletionPolicy Retain. This created the volumesnapshot and the volumesnapshotcontent object with DeletionPolicy: Retain
2. Delete the volumesnapshot object created above. Now because the DeletionPolicy was Retain the volumesnapshotcontent object is preserved.
3. Patch the volumesnapshotcontent object to set its DeletionPolicy to Delete
4. Now delete the volumesnapshotcontent. At this step, the object's finalizer snapshot.storage.kubernetes.io/volumesnapshotcontent-bound-protection doesn't remove itself and the deletion just sits at the terminal.

What I expected:
I expected that the object to be deleted.

Is this a valid scenario for the CSI drivers? Is my expectation from the issue correct?

@ashish-amarnath Can you test this using the latest code from external-snapshotter? This might be the same issue as reported here: kubernetes-csi/external-snapshotter#292. We are cutting release 2.1.1 soon with this fix so you can wait for that as well.

[ashish-amarnath]

Will give that a try. Thanks!

@ashish-amarnath, 2.1.1 is released for external-snapshotter.
