I moved last week, and finally got around to plugging in the raspberry pi today, connect it via Ethernet, and plug in my external HDD. When I tried to test it out though, I can still sign in and access my whole library but nothing will actually play. I’m not really good at this stuff but I’d appreciate any help (and patience) you guys would be willing to give me. As mentioned, I’ve got it set up on a raspberry pi. It all worked fine before the move. If anyone has dealt with this before I’d appreciate some tips. At the old place I set up a static IP for it too if that helps at all.
You mentioned “plugged in my external HDD”. I presume you are using a USB drive. When it connects to RPi, the contents are mounted somewhere which can be accessed by applications. This “somewhere” most likely got changed when you last unplugged and plugged it back.
Try to locate this mount folder (perhaps called “mnt”) then see if you reference the same path inside Jellyfin.
Avoid this problem by adding its uuid to a fstab line so it always mounts to the same place
I’m going to try this later on and see if it helps. When I moved from windows to Linux on my pc I had a similar issue with steam not recognizing my external, and doing this solved it. Unfortunately I can’t remember how I did that now so I’ll have to try and find a guide online or something.
