How can I make sure the HDD are hibernating on QuTS 5.2.7 ? Is there a log where I can see something like “Internal disks woke up from hibernation“ and time.
Due to the way QTS works, disk sleep is basically unobtainable.
A serious oversight, in my opinion. And what does he do with them if the system installed on M2 ? In the configuration 2xM2+2xhdd? It’s interesting and I want to understand
The OS is always installed on all internal drives in spanning RAID1 (md9 and md13)
I see, thank you. So, if the disks aren’t in a mirror, the system won’t install on them and they’ll go into sleep mode? What happens if I add disks and use a raid5 instead of raid1?
You have no influence on md9 and md13 ..it’s always a RAID1 no matter what disk layout you chose
You can break it, if you know your way around SSH
The whole purpose of a NAS is to be in an environment where users have ready access to files and “quickly". Putting disks to sleep is not something that will fulfill that mission.

If users work according to a schedule, why waste energy and resources? That’s what sleep mode is for. The exit from it is quite fast (1-3 second), and the pause before sleep is adjusted by the settings (30 min. is typical).. Competitors have implemented it (syn, мany years ago). It’s cost-effective. Use it if you want, or not. Settings in the menu.
So if there are no users accessing the NAS during a certain window and no other tasks on the NAS need to happen, then set up a power schedule to shut it down and then restart it when needed. That’s going to consume much less power than just spinning down the drives.
I found a FAQ, Why can't my NAS drives enter standby mode? | QNAP
and it’s a good start to check if you are looking for why your system can’t get into sleep mode.
Colleagues, before treating a disease, it’s necessary to first diagnose it. The entire discussion above is off-topic. The initial question: where can I see the actual fact of hibernation? In which log?
There used to be a working script but it’s usefulness was diminished as internal mechanisms have changed
Thanks, but that’s another case of “searching for what’s preventing hibernation.” I just need the fact that hibernation is working. I just want to open the log and see: the drive exited hibernation at 5:55 PM, for example. That means the drive entered hibernation and hibernation is working! Maybe no one cares why it exited hibernation. That’s a separate question, and the script and all the reasoning answer it.
