bl00dy-c0d3 Posted March 12 Share Posted March 12 Hey Guys, for some reason my HDDs never spin down. I can spin down them manually but they will spin up again after some seconds. I checked File Activity and Open Files but there is nothing accessing my drives. VMs are on my SSDs, so that they can run without making any noice. But even with VMs and Docker completely disabled they dont spin down. The timing is set to 15min for automaticaly spin down. I appreciate any help Thanks Marcel unraid-diagnostics-20240312-1300.zip Quote Link to comment
itimpi Posted March 12 Share Posted March 12 Have you tried disabling the docker and VM services to see if the disks then spin down? Quote Link to comment

bl00dy-c0d3 Posted March 12 Author Share Posted March 12 Sometimes i am able to manually spin it down for 2 minutes before they spin up again. Nothing to see in File Activity Quote Link to comment

Do you have Tirbo Write enabled? If so writing to any disk would cause all drives to spin up and in the diagnostics something is writing to disk6. Quote Link to comment

Solution itimpi Posted March 12 Solution Share Posted March 12 This is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page. The Unraid OS->Manual section in particular covers most features of the current Unraid release. Quote Link to comment

Out of your experience, is there a hugh write speed difference when turning it off? Quote Link to comment

There can be. Ideally to get best performance you want things that might otherwise keep disks spun up to be on a SSD pool external to the main Unraid array. Quote Link to comment

I will probably just use a cronjob to turn it off by night and on by day. mdcmd set md_write_method [0,1] should do the trick Quote Link to comment
