@chmill-zz `VMSSVMUpdateAsync` operation was throttled, it happens when there are disk attach/detach on a lot of agent nodes simultaneously.

hi @achetronic do you have more details about VolumeSnapshots API? Thanks.

one implementation is using `tar` command to take "snapshot" of current volume directory, could refer to https://github.com/kubernetes-csi/csi-driver-host-path/blob/f5fd42e78f3884ed6b780d23c1c43798a0d29d35/pkg/hostpath/controllerserver.go#L555

could refer to the hostpath csi driver snapshot implementation: https://github.com/kubernetes-csi/csi-driver-host-path/blob/9be5dd74a7fc2436c4334820156056b74821998e/pkg/hostpath/controllerserver.go#L497-L585 any volunteer?

seems it's not that complex implementation, let me try implementing it, stay tuned.

if `csi-nfs-controller` is running on one worker node which is restarting, the `csi-nfs-controller` would not accept any request, so that's by design.

@yingding not sure, I think you should get `kubectl logs csi-nfs-controller-56bfddd689-dh5tk -c nfs -n kube-system -c csi-provisioner` to take a look if there is any PVC provision.

v4.1.0 is master branch, it's not released yet
