Hi Team,

I'm currently running the following:

CentOS 7.9, CSI: 1.4, K8s: 1.20, SDC: 3.5.1.1

I followed the instructions in the latest release of the CSI plugin but I get the following "CrashLoopBackOff" errors:

vxflexos snapshot-controller-0                          1/1 Running                   0 3h39m
vxflexos vxflexos-controller-654d7445fc-4zbkl  4/5 CrashLoopBackOff 60 3h39m
vxflexos vxflexos-controller-654d7445fc-tnd8w 4/5 CrashLoopBackOff 57 3h39m
vxflexos vxflexos-node-89flx                              2/2 Running                   0 3h39m
vxflexos vxflexos-node-8dpf7                             2/2 Running                   0 3h39m
vxflexos vxflexos-node-hkkws                            2/2 Running                   0 3h39m

I also noticed this:

default csi-snapshotter-0                                    3/3 Running                    3h44m <--- shouldn't this be in the same namespace as the vxflexos controller?

and when I run kubectl logs csi-snapshotter-0 csi-snapshotter, I get these errors:

I've downloaded the files from here: https://github.com/kubernetes-csi/external-snapshotter/tree/v4.0.0/client/config/crd

and just ran kubectl create -f snapshot.storage.k8s.io_volumesnapshotclasses.yaml for each one. 

Hope someone can help resolve these issues? Thanks!
