How can I ensure my disks power down when not in use?

Post by nycoy » Fri Feb 21, 2020 7:47 pm

Hi - I have TS453Pro running 4.4.1.1146, although this issue has existed throughout my ownership of the NAS as far as I can remember so is not version related.

I am trying to understand why my disks still seem to be active/spinning even though I have Enable Disk Standby mode set to switch them off after 5 minutes. Please note I am not talking about the fact that the lights are on on the NAS, but talking about actually being able to hear the disk spin and the heads move.

I only really use the NAS for Plex, and as a backup device where I manually copy files as and when I need to - not via automated backups/scans. So when there is no one using Plex and I am not copying files to it I would like it to power down the disks after 5 minutes.

In System Status>Service Status, everything is disabled except: DNLA Media Server, Download Station, Microsoft Networking, Multimedia Services, Qsync, Rsync Server

If I go into AppCenter, there are a number of apps there. Of these, some have the "stop" option when I click on the drop down arrow (which implies to me that they are running/active?): Download Station, Helpdesk 3.0.0, JRE 8.151.2, Media Streaming Add on 441.1.1.4, Qboost 1.3.0, Qsync Central 3.2.0.7 , SSD Profiling Tool 1.0.1115

So I assume that there are a number of services and processes running that perhaps I do not need....? Can anyone confirm which of these services and apps I can stop without affecting my ability to continue using Plex and also to connect to the NAS from my windows PC?

Am I right in thinking that I need to keep Microsoft Networking running in order to be able to connect to it via Windows 10? ANd also I assume Plex doesn't need DNLA Media Server as it is in effect it's own media server?

Any advice appreciated, on how I can ensure the disks power down when not in use by Plex or windows file copies.
Cheers.

As stated getting the HHDs to go into standby mode is tricky with qnap devices. From my experience 4.4.1.1146 build 20191206 was one of the worst. Since 4.4.1.1216 build 20200214 was released and installed, standby mode has been working as expected, maybe you should give it a try.

I've updated to the latest version but as I mentioned, it has been like this throughout many recent versions.

I have also stopped a lot of the services. Hopefully that will reduce the possibilities for processes reading or writing to the disks.

I will keep an eye (and ear) on it...

If you do let us know how you did it.
Virtually impossible without uninstalling nearly everything.
