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?


That is exactly my usecase. Especially during the week the server is used only in the morning and in the evening. It is not accessible outside my home wifi either. So the drive is sleeping like 20 hours a day instead of running needlessly.
My first thought behind this was also wear of the drive but seems like that is a small issue. Cost of electricity is however another one, but to be fair I never calculated that. Might be less than in your case but still money spent on something not being used.
