ivez Posted July 18, 2017 Share Posted July 18, 2017 Hi all, I am on 6.3.5 and all my drives are staying spun up. Never had the issue before and i've tried rebooting a few times. Diagnostics are attached. Any suggestions are very welcome. tower2-diagnostics-20170718-1031.zip Quote Link to comment
SSD Posted July 18, 2017 Share Posted July 18, 2017 If you've double checked all of the skin down settings (global and individual disk settings), and you don't have frequently accessed user shares on every disk, I'd suggest powering down. Rebooting does not fully reset the drives. Long ago I remember there were situations where the drives needed to be powered down to reset them. Its a long shot. Quote Link to comment
JorgeB Posted July 18, 2017 Share Posted July 18, 2017 You can also spin them down manually and check if they stay spun down or spin back up right way, if the latter something is accessing them. Quote Link to comment
SSD Posted July 18, 2017 Share Posted July 18, 2017 Another thought ... If you are running in turbo write mode (using the plugin or not), that could definitely cause disks to not spin down. Quote Link to comment
ivez Posted July 18, 2017 Author Share Posted July 18, 2017 Thanks for the tips guys. I couldn't find any settings for turbo write, is it disk settings? I've manually spun all drives down and will perform a proper shutdown tonight. Quote Link to comment
Frank1940 Posted July 18, 2017 Share Posted July 18, 2017 I have observed that it seems like getting some types of information (SMART data, etc.) about drives will cause them to spin and then they don't seem to spin down automatically. I have daily status reports e-mailed to me every night and I check in the morning for any drives spun-up (I.e., those showing a temperature) and occasionally (once or twice a week) there will be one. I simply login and spin the whole array down and that fixes the problem. I have never really devoted much time to seeing what is causing it as it is more a nuisance than anything else.

You are in the right place but it is actually called " Tunable (md_write_method): " and you set it to 'reconstruct write' for turbo write. Quote Link to comment
ivez Posted July 18, 2017 Author Share Posted July 18, 2017 Mine is set to auto. Quote Link to comment
ivez Posted July 18, 2017 Author Share Posted July 18, 2017 After i manually spun the drives down CPU usage was 1-2%. They have all spun up again and i notice and have noticed for the last few months (over several versions of unraid) that CPU usage tends to hover around 20-30%. I've attached my HTOP showing the culprit services. Any ideas chaps? Quote Link to comment
