I noticed my home servers SSD running out of space and it ended up being my Jellyfin Docker container which wasn’t clearing the directory for transcodes in /var/lib/jellyfin/transcodes correctly.
I simply created a new directory on my media hard drive and bind mounted the above mentioned directory to it. Now Jellyfin got over 1 TB of free space to theoretically clutter. To prevent this I simply created a cronjob to delete old files in case Jellyfin isn’t.
/usr/bin/find /path/to/transcodes -mtime +1 -delete
Easy!
How much RAM would this consume?
that does not matter you can just download more ram
Every transcode could need as much disk space as the size of the file you’re playing. If you have a media file that’s bigger than your available RAM the transcode will propably cause problems because you will run out of RAM.
