rook: Kubelet log spamed by "Operation for "/var/lib/kubelet/plugins/rbd.csi.ceph.com/csi.sock" failed."

Is this a bug report or feature request?

• Bug Report Actually I’m not sure, this is a bug or normal behavior. I try rook v1.1 the did clean up as described in https://rook.io/docs/rook/v1.1/ceph-teardown.html

Now, now more rook’s stuff in my cluster, but when I check kubelet log its spammed by:

Environment:

• OS (e.g. from /etc/os-release): Debian GNU/Linux 10 (buster)
• Kernel (e.g. uname -a): Linux KubeNode2 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5 (2019-06-19) x86_64 GNU/Linux
• Cloud provider or hardware configuration: VM on top hypervisor (baremetal)
• Rook version (use rook version inside of a Rook Pod): v1.1
• Storage backend version (e.g. for ceph do ceph -v): destroyed so can not check, i follow v1.1 documentation
• Kubernetes version (use kubectl version): Client Version: version.Info{Major:“1”, Minor:“15”, GitVersion:“v1.15.2”, GitCommit:“f6278300bebbb750328ac16ee6dd3aa7d3549568”, GitTreeState:“clean”, BuildDate:“2019-08-05T09:23:26Z”, GoVersion:“go1.12.5”, Compiler:“gc”, Platform:“linux/amd64”}
• Kubernetes cluster type (e.g. Tectonic, GKE, OpenShift):
• Storage backend status (e.g. for Ceph use ceph health in the Rook Ceph toolbox): destroyed as i did cleanup

Thank you
