Docker does not issue unmount after mount failure

[yuva29]

Below is the docker behavior based on mount option

policy1/v4:/mnt:nocopy -> during run there is only mount request; and calls unmount after mount failure policy1/v4:/mnt -> during run docker issues mount->unmount->mount requests; never calls unmount after mount failure

Here is the similar issue for -w mount option : https://github.com/docker/docker/issues/22564
