The issue you are facing:
I have some files that apparently no longer exist on the hard disk, but have not been removed from the database. Thus the client gets a 503 when trying to sync. Also in the Web UI there is an error shown.
How can I get a list of files which no longer exist on the disk but are in the database? How can i fix the database?
This help entry from 2019 seems to ask the same question, but is now almost 3 years old and without a good answer.
