Bit lazy, but I read the guide, which is nice, also looked through the forum but no avail. I have some trouble with permissions on the volume folders. I installed a Logitechmediaserver in Docker, and can mount my /music folder ok, but the medie-scanner cannot scan subfolders in the mount. There must be something with Docker and user/group. A little hint would be nice.
A "quick" solution would probably be to give execute and read rights on all subdirectories and read rights on all files to "all" (chmod a+rx and chmod a+r respectively).
EDIT: I forgot to ask, which docker image is it you're using for LMS? I'm searching for one myself
