I have migrated my Plex server from my main PC to a Raspberry Pi 5, in general it works quite well, but I have noticed that when browsing libraries with collections or within the collections section, the CPU usage becomes 100% This occurs in a more accentuated way the more collections there are in the library, I’ve been thinking about it and this doesn’t make sense to me, since collections should be like just another normal archive.
I copy the Plex Media Server data directory from “%LOCALAPPDATA%Plex Media Server/” to “/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/”
For some reason, some folders and files had write permissions blocked, as they could not write to the “/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Cache/PhotoTranscoder” folder PMS kept transcoding the covers in a loop indefinitely.
I was able to diagnose this by simply opening the plex console, with error filtering in one browser tab and collections in another tab.
The most efficient way to solve it is to open the file manager as root, navigate to the folder “/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/” and allow anyone to change the content, after refreshing the metadata everything should be fine.
