Sorry, me again. Just updated my docker setup to the latest Jellyfin but am now facing the issue that ever since I updated several days ago, my hdd is not going to sleep as it did before.
I use hd-idle to spin down my external harddrive which has everything Jellyin on it, media and configs. Worked perfectly fine before upgrading to 10.11, for several years.
After updating to 10.11 this does not work anymore, my hdd is running without any sleep and with no activity on the server. Nothing changed in how the server is used. There are no scheduled tasks running continuously. When I go to the logs in the dashboard it doesn’t record anything happening either during the times it normally would have put the hdd to sleep.
Anyone got any idea what it is or how I could narrow down what it could be that seems to keep writing on my hdd? Or is this intended behaviour of the new version?


Multiple times a day and many times a day isn’t necessarily the same thing. Also just having a 1-2 hours long timeout might still be a viable option preventing repeated spin ups, but still allowing spin down during longer unused periods.
While probably not worth it for your particular case, it might will be for others reading this. Ideally, one could observe the access patterns for a while a find a suitable timeout setting.
