What happened:

When mounting a filesystem volume with a CSI driver, kubelet creates the NodePublishVolumeRequest.target_path directory where the volume is to be mounted.

What you expected to happen:

According to the CSI 1.0 spec, kubelet must not create that directory, only its parent:

The CO SHALL ensure that the parent directory of this path exists
and that the process serving the request has `read` and `write`
permissions to that parent directory.
For volumes with an access type of block, the SP SHALL place the
block device at target_path.
For volumes with an access type of mount, the SP SHALL place the
mounted directory at target_path.

Environment:

• Kubernetes version (use kubectl version): Kubernetes 1.13.x and 1.14.0
