The team has made some great progress with this:

How to find any missing images?

Upgrade to the latest version of Discourse and run the task rake posts:missing_uploads again. The task itself will try to recover the missing old scheme uploads from local “uploads” and “tombstone” directories. At the end it will display the count of the uploads which are not found both in database and local storage.
