I have been using plex server for a while now and would like to suggest a small feature.
Basically be able to filter movies, Series etc by Unavailable.
So I had the bad experience of one of my harddisks die and a bunch of my favorite movies gone forever
I realized metadata for the āUnavailableā movies was still present ( Awesome btw) , so if I could filter movies in that condition I could try and retrieve them again.
Even if we could export somehow a list of that āUnavailableā movies would be great.
Do also make sure that your database is not damaged. Because if it is, you might lose even more data in the future and it might also be the cause of the non-working āTrashā filter.
Or inspect them yourself. Take a look at the Plex Media Server.log file and seek for messages about database corrupt or malformed.
If you find these, you may have to repair your database. https://support.plex.tv/articles/repair-a-corrupted-database/
