Synology NAS hibernation?

1pudding1 · 30 Jul 2012 at 07:56

Hi,

Got my 212j last week with a 1TB drive installed. How can I check its going into hibernation? Is there a log somewhere to view? I've seen other peoples logs that state that hibernation has started, stopped etc.. Which log is this, does it need another package/service started?

Thanks.

Open up the web interface and in the top left there should be an icon, which has 3 grey squares and a blue triangle on it. Click on that and it will open a small window containing several shortcut icons. One of those icons will be a clipboard with a magnifying glass hovering over it and will be called 'System Logs'. Click that and it will open up all the system logs in a new window so you can see what is running including hibernations etc

Thanks. There isnt a magnifying glass over a clipboard, but there is a Log tab in the system infomation. However, there isnt a thing about hibernation in there at all. Just a few entries about me logging on and when I booted the NAS up about file systems starting. Hmm....guess something is keeping it awake constantly. Time to start unplugging things I guess.

I was thinking about getting one of these for my shared media drive, but Im guessing I'll be using more power then Im using now.

At the moment I have the shared media hdd in my main pc and ppl can use it as and when because Ive set all laptops to wake up my main pc from sleep remotely and then my main pc goes to sleep when idel. But If I got a Synology NAS it will be on 24/7 so using more power in the long run then just sharing the hdd on main pc.

With the price of power now, you have to think about these things.

Which version of dsm are you using. Log into the web interface and it will be up there in the top left. It opens a small window and it should definately be in there.

I agree. However a NAS can be set to go into hibernation and wake when needed. And when it is awake it is using a fraction fo the power a pc would be. It therefor makes sense to use a nas in that situation rather than a pc.

The LED's on the unit will go out on each disk if it's hibernating.

Oh and hibernation events don't appear in the system logs.

But even in hibernation the NAS uses more power then a PC in sleep

Synology NAS Power Consumption : 17.6W (Access) ; 5.5W (HDD Hibernation)
My PC uses about 1 - 2watts in sleep

5.5watts don't sound much I know but it all mounts up.

Probably averages out as the PC needs x times more when it's awake.

NAS uses like 4 watts hibernating and 12 watts awake.

Make sure the NAS isn't working as the local browse master (not sure where it is on the Synology but its well known for keeping NAS boxes from powering down properly.

I doubt the power useage between a NAS in hibernation and a sleeping PC will be in any way significant IIRC my QNAP uses 0.3watt when its in a low power state.

Any Netbios events will wake it too.

I found that the Zune software for my Dad's Nokia Lumia was a culprit in my environment, and Canon Network Scanner (for the printer) was spamming ARP requests everywhere.

Yeah was just thinking that as my pc uses about 160watts when awake, but during the daytime Im using the pc anyway, so the daytime usage on pc dont really count and my shared drive only really gets accessed evenings/night and morning.. So no I prob wont be using anymore power then I am now. but I guess its another thing to add to the list that needs power 24/7 if I got a NAS.

Fair enough. But for people like me, and I suspect most others, they want a solution they can leave on instead of their pc. Not only that but power aside it offersa lot of redundancy. Though that is easily achieved inside a pc too. Suits some not others.
