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?
