Can't delete files created by Docker user

I know the answer to this is going to be something very simple, but I couldn't a clear way forward by googling it. I'm a bit reluctant to try a bunch of changes without knowing what I'm doing..

I have a new install of OMV5. I set it up using the PDF guide, all good. I can access my shared folders from a windows PC. I can copy, move, delete files on the shares ok. I learned about Docker and Portainer as well. Part of that was setting up a dedicated user for Docker, I called that user Docker1. I've got SABNZB running in Portainer and used the Docker1 user when I set that up. It all works fine.

When a download completes I can't delete the file from the shared folder. I get the error " File Access Denied - you require permission from unix user\docker1 "

Can someone please point me the right direction?

In your docker container configuration try setting an environment variable UMASK=000

Thanks. I just tried that, no joy.

It only works for new files downloaded after you made the change and restarted the container. Have you done all that?

Yes. I deleted everything from my completed downloads folder using the CLI. In portainer I stopped the container, edited the stack and added the environment variable you suggested, saved the stack. The container is then up and running.

I then downloaded a new file and could not delete it from the Windows share.

I found the answer. It was a setting in SABNZB. Folders / advanced. PERMISSIONS FOR COMPLETED DOWNLOADS. I changed the setting from nil (blank) to 777 and that's fixed it.

Apologies for the false alarm. The error message made think it was a OMV folder or user permissions issue..

I'm not a fan of 777, and would rather just set permissions properly.. but I guess if you're happy.

I'd be thankful for your further guidance. I guess its the execute part we want to leave out? I believe original permissions were 644, if i add group and public write permissions it should be 666?
