Summary of the issue you are facing:
I think I am doing something gigantically wrong I can’t really see, please help 
At first I added a local external storage from a mounted disk, where I store the AIO borg backup and camera videos acquired via FTP, so far so good, no issues.
Then I wanted to add another disk with music, setup with the Nextcloud Music app.
Both external storage are marked 
first local external storage works well
but the second one with music(a), can’t read or write the content (I am a member of Media Admin), below the error while creating a new folder and a file (see logs below, note that for folder creation there is no logged error)
In docker compose I mount the whole /media/ folder
- NEXTCLOUD_MOUNT=/media/
I added full RWX recursive permissions to www-data to /media/musica but still no luck
current folder structure and permissions

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
