NAS-newbie Posted February 21, 2023 Share Posted February 21, 2023 I have all my shares set to either cache:prefer or cache:yes but I still see some periodic activity is causing one disk of the array to never spin down and also causing the parity drive to remain spun up (so seem to be "updates of some kind"). Naturally I want my disk to spin down so need to figure out what is causing this... Are there any type of disk update activity (changed ownership/permissions or anything else) that is not cached and instead go directly to the array or any other thoughts on what this may be or how to debug the problem further (when file activity plugin seem to be "bypassed" showing no activity what so ever)?

itimpi Posted February 21, 2023 Share Posted February 21, 2023 You are likely to get better informed feedback if you attach your system’s diagnostics zip file to your next post in this thread so we can check how things are set up. Quote Link to comment

itimpi Posted February 21, 2023 Share Posted February 21, 2023 Your diagnostics show that the ‘appdata’ and ‘system’ shares have files on disk1 so that could explain your symptoms. They are set to Use Cache=Prefer, but unless you disable the Docker and VM services while running mover the services will hold files open which stops mover from moving the files used by theses services to the cache.

NAS-newbie Posted February 21, 2023 Author Share Posted February 21, 2023 Any thought on why it behaves like this or what I am supposed to do to fix it and avoid it happening again? Do one in general need to disable dockers and VMs when running the mover and in that case how to automate that (and why is it not done automatically by UnRAId if needed)?! Quote Link to comment

You only need to disable these services once to get the current state cleaned up for these default shares. When the files are where they should be you can re-enable them and everything should then just operate fine. The problem tends to occur when you first start these services without a cache pool attached. As a result the services support files end up getting created on an array drive. When you later add a cache pool Unraid puts any new files for the "Prefer" type shares on the cache pool and tries to move what other files it can to the cache pool. It fails to move these services support files because the services are holding them open. Quote Link to comment

NAS-newbie Posted February 22, 2023 Author Share Posted February 22, 2023 Seems to have solved the problem. Just wondering why the disk1 file access did not show up in the file activity plugin....? Quote Link to comment

It may not be making that many accesses. Perhaps just keeping the file open might be enough? 1 Quote Link to comment
