Errror mkdir /host_mnt/c: file exists when restarting docker container with mount

[eino-makitalo]

Expected behavior

Container should start normally

Actual behavior

C:\Users\einom>docker start f96263b10996
Error response from daemon: error while creating mount source path '/host_mnt/c/Users/einom/Documents/projects/cap/src': mkdir /host_mnt/c: file exists
Error: failed to start containers: f96263b10996

Information

Docker version: 17.12.0-ce-win47 (15139)

Windows 10 Pro
Version: 1709
Build: 16299.192

Whole C drive is shared with docker VM

Steps to reproduce the behavior

1. start container with command similar than me in my home dir
   docker run -d --name sonarqube -p 9000:9000 -p 9092:9092 -v c:/Users/einom/Documents/projects/cap/src:/src:rw sonarqube
2. use container and enjoy that directory in container /src is mounted OK
3. docker stop this container
4. docker start container ... and you got error ... mkdir /host_mnt/c file exist.

Of cource it exists because if I understand correctly this /host_mnt/c should point to my whole C: drive ?

I had the same issue. I was able to resolve it by running:
docker volume rm -f [name of docker volume with error]
Then restarting docker, and running:
docker-compose up -d --build

I tried these same steps without restarting my docker, but restarting my computer and that didn't resolve the issue. What resolved the issue for me was removing the volume with the error, restarting my docker, then doing a build again.

I have the same issue, not even sure it's only after a container restart, seems like a "time-out" :-/

Got same error when trying to do docker-compose run

I was just working on a dev-custom image with some volumes when suddenly i got a weird behaviour so i restarted the container and when tried to run that container the error happened

$ docker-compose run --rm --service-ports web
Starting erpassetel_db_1 ... done
Error response from daemon: error while creating mount source path '/host_mnt/c/Users/randomUser/Documents/folder1/subFolder2/Addons': mkdir /host_mnt/c: file exists

After 5 minutes i just tried to run the containers again and it all worked well again

Got the same on windows:

 docker run -it -v "C:\git\somerepo\somefolder":/usr/lib/src alpine:3.7
docker: Error response from daemon: error while creating mount source path '/host_mnt/c/git/somerepo/somefolder': mkdir /host_mnt/c: file exists.

On Windows this may be due to a user password change. Uncheck the box to stop sharing the drive and then allow Docker to detect that you are trying to mount the drive and share it.

I was able to resolve it by running at Windows PowerShell (Admin).

I do have a similar problem. Yesterday I created a container at D:\Users\myname\docker\test (Windows 10 Pro). When I try to restart the container using

docker run -d -p 8008:80 -v D:/Users/myname/docker/test:/var/www/html php:apache

I get:

cd72fdb49e2d5067c0f5d4ff6ab0ae87c038db8b22492e280c9e80fe550e3499 docker: Error response from daemon: error while creating mount source path '/host_mnt/d/Users/myname/docker/test': mkdir /host_mnt/d: file exists.

I tried to start the container with the normal command shell and with Windows Power Shell, neither works. Any ideas?
