CSI driver debug tips

Case#1: volume create/delete failed

  • locate csi driver pod
$ kubectl get po -o wide -n kube-system | grep csi-smb-controller
NAME                                     READY   STATUS    RESTARTS   AGE     IP             NODE
csi-smb-controller-56bfddd689-dh5tk      5/5     Running   0          35s     10.240.0.19    k8s-agentpool-22533604-0
csi-smb-controller-56bfddd689-sl4ll      5/5     Running   0          35s     10.240.0.23    k8s-agentpool-22533604-1
  • get csi driver logs
$ kubectl logs csi-smb-controller-56bfddd689-dh5tk -c smb -n kube-system > csi-smb-controller.log

note: there could be multiple controller pods, if there are no helpful logs, try to get logs from other controller pods

Case#2: volume mount/unmount failed

  • locate csi driver pod and make sure which pod do tha actual volume mount/unmount
$ kubectl get po -o wide -n kube-system | grep csi-smb-node
NAME                                      READY   STATUS    RESTARTS   AGE     IP             NODE
