High Disk Activity - MediaMaan - 2024-10-29

Since I switched to the Bbergle-jellyfin docker on unRAID, I've noticed a LOT of disk activity. It genuinely seems excessive.
Multiple times per day, the disks are "chunking" away. Prior to installing Jellyfin, this wasn't happening.

My guess is that it has something to do with the Medial Library, and scanning.
A look at recent logs for example, shows the following :
[09:26:02] [INF] [76] MediaBrowser.MediaEncoding.Encoder.MediaEncoder: Starting /usr/lib/jellyfin-ffmpeg/ffprobe with args -analyzeduration 200M -probesize 1G -i file:"/data/tvshows/HDTV/Tom Clancy's Jack Ryan/Season 4/Tom Clancy's Jack Ryan - S04E05 - Wukong.mkv" -threads 0 -v warning -print_format json -show_streams -show_chapters -show_format

What is Jellyfin trying to accomplish here? Why is it probing multiple times a day?

I want Jellyfin to monitor the various libraries, so I checked "Enable Real-time Monitoring" in order that new files are added to the DB within a few moments of being placed in a Directory. But having such frequent disk activity is a little concerning when nobody is connected to Jellyfin. Especially since it is running the disks for hours at a time, day & night.

Is this a Real Time Monitoring issue, or something else? What settings should I be playing with to sort this out?

Thanks for your help!

Do you have trickplay enabled? Or chapter image extraction? Depending on how you've got jellyfin setup and what your hardware specs those two tasks can take hours to complete.

But we'd need to see your full server log via pastebin.
