due to the manual detach, the kubelet thinks that the disk1 is already attached to the node, thus CSI driver won't be called (no NodeStageVolume call) to verify the drive....
the data path does not go through csi driver, it's the issue between cifs driver and azure file server, pls file a support ticket to azure file team, thx
