'Drive sharing failed for an unknown reason

[astannard]

• I have tried with the latest version of my channel (Stable or Edge)
• I have uploaded Diagnostics
• Diagnostics ID:B5EDDF18-C4CF-4711-B79E-9351539163DC/20190103093944

Expected behavior

I use docker-compose to bring up a docker image, windows prompts me to share the drive, I enter username and password and docker-compose completes.

Actual behavior

Once I enter password to share the drive I see the following error appear in the command window:
ERROR: for server_uikitrails_1 Cannot create container for service uikitrails: b'Drive sharing failed for an unknown reason'

ERROR: for uikitrails Cannot create container for service uikitrails: b'Drive sharing failed for an unknown reason'
ERROR: Encountered errors while bringing up the project.

Hi,

I am also facing similar error. I am not getting above error but Docker just freezes when I share any drive with docker. I am using Windows 10 Pro 64bit. Below is the docker version detail that I am using:-

Hi, an update for anyone who might come across this, and needs help as they sit at their computer crying into their latte.

The issue was the user account I was using to grant share access, I was using a domain user. I had to create a local user on my computer to share the drive access, then it all worked as expected. Please see the following article for help in the matter: http://peterjohnlightfoot.com/docker-for-windows-on-hyper-v-fix-the-host-volume-sharing-issue/ p.s. the websites a little slow

Hi Astannard,

I tried steps proposed by you, but still not able to share the drives between Win10 and Docker containers with Hyper-V. Could you please help me with this?

Regards,
Sanjeev

[astannard]

Sanjeev, I would check your computers event logs for a related error message. I did not find one for me though but my docker instance did not crash, it just did not share the drive with no failure message or explanation.

The other thing to try if you see no error message in the logs would be to try sharing the drive from a command window, you might see an error pop up then??

@astannard I am also facing the same issue. Please see the details below:

Steps Tried:

1. Docker gives me error saying Windows Firewall is blocking the File sharing
2. When i start docker as admin user it says Drive Sharing failed for an unknown reason
3. Tried to run this command from Powershell docker run --rm -v c:/Users:/data alpine ls /data
   but it gives me same error.

Any work around for this issue? I am using Docker Stable version.

I checked the shared checkbox for my C: drive and ran the command it worked for me.

Hi, everybody!

I was facing the same issue when starting containers with docker-compose I got the error:

A firewall is blocking file sharing between Windows and the containers.

Then I checked settings for Docker and under Shared Drives section I tried to check the checkbox for C: drive as @inthrakumarp did, but after hitting apply checkbox unchecked itself.

Then I copied the line docker run --rm -v c:/Users:/data alpine ls /data into Powershell, ran it and got the error:

Drive sharing failed for an unknown reason.

But after this error, I decided to just try restarting Docker. After the restart, I tried to check the checkbox in the Shared Drives section once again and now it stayed checked and everything is working as it should.

I was using Docker Stable version.

@astannard Hey, might want to edit that link to peterjohnlightfoot.com out of your post - looks like the domain is parked now and is just redirecting to malware sites.

This helped me immensely. Keep in mind that you must have an activated copy of windows to create the user account.

Also, you can't have your data in the domain user folder, as you will get a permission denied error. It must be somewhere public.

I checked the shared checkbox for my C: drive and ran the command it worked for me.

it worked for me too. Thanks!

I just found one more solution which worked me. On powershell just run below command:

Set-NetConnectionProfile -interfacealias "vEthernet (DockerNAT)" -NetworkCategory Private

It's very very slow.

[jamesbluecrow]

A simple docker restart worked for me 👍

I've tried many things but this one helped at last.

[almothafar]

Here is the way that driving share worked for me:

1. First of all, I'm Under AzureAD, so I have to create a new local admin user.
2. I logged in that user to make sure he got activated correctly, then logged out to my original user.
3. Did Factory Reset and tried to share my drive, asked me to input username and password, used the newly created account, but it keeps asking me for username and password.
4. I clicked cancel and did the Reset factory again.
5. Click share drive, worked without any question.

Does it make any sense? not at all, but it worked, how and why? I have no idea, but it is working now so who cares! 😄

You must change to 8.8.8.8 and then you are going to click the drive C:
