Server Version#: 1.32.7.7621
Player Version#: not relevant
os: Ubuntu 20.04.6 LTS
I typically only follow storage usage in my /home paths and just this weekend discovered I am suffering from this same issue to the tune of 577G. I have also posted in the server forums: HELP - Plex Media Server/Cache/PhotoTranscoder is 577G!
My settings are correct, but evidently it has not deleted any entries since 2021.
I am going to try playing with jdupes or fdupes, but really would like a solution from PLEX!!!
