more disk standby timeout options

[rm_]

In system administration -> Hardware under "Enable hard disk standby mode" i can set the timeout before putting disk in standby up to 1 hour. It would be nice to have longer timeout options like 2h, 4h, 8h. So that i'll be sure to shut down disk during night but be moderately confindent that nas users won't yell at me when they forget a file open on the nas and lose their changes when the disks go to standby. Now i have to disable disk standby which is not great from a power management perspective. Thanks in advance.

They wont loose anything. Any active open channels to files will remain - the disks will spin-up when the effective disk access is required again.

I've got reports about this kind of issues with indesign opening a file over AFP on a qnap device.

what do you mean when you say you got reports? not trying to dismiss your concern here, just asking if you can share that information

I have a user reporting losing its changes when working with indesign, twice. For some reason there are no netafp logs on qnap devices (why?) and i haven't seen the indesign error with my eyes but i'm sure that after the error and reopening the file the disk are spinning. So really this is just speculation. It may be a bug in upper layers or adobe applications being not very robust against read errors, don't know. Anyway I've disabled disk standby today so let's see if it happens again tomorrow Said that the request i've made would not take more than 2 minutes to implement

Does this disk spin down/ standby mode can configure as longer time? Any Update? Are there any options can let me choose like if no one access the data for 1 (24 hrs) or 2 (48 hrs) days? - I just wanna save the eco.

On the other hand, personally I believe harddisk spin up and down will cause more stress on the harddriver electrionic and mechanical parts. I do not have evident to show you, but you can setup two same configure i7 system and running 3.5 inch harddisk. One system shutdown every 8-10 hours daily when the staff finish work and the other one keep live 24x7. And see what is going on

I choosed to disable hard disk standby mode.

That doesn't make sense as they would never kick in. The NAS is doing internal housekeeping nightly and if it is powered on, the disks will spin up at least every night.

I agree. On the other hand desktop disks are in fact designed and manufactured to cope with relatively frequent (at least daily) spin ups.

Personally I don't think it makes sense to overthink a thing like this unless you're running a huge data center. With the low number of disks ordinary users have, you will get a spread anyway. One disk that is babied can fail before another one that is frequently powered on and off and exposed to a lot of thermal variations.

Use the disks in the way you think is good for the use you have and buy new disks when the old ones fail would be my simple advice. The only thing to avoid is in my opinion a very low timeout like 5 minutes if the NAS use is anything but extremely predictable. It would be a waste to have 4 spindowns in an hour if the NAS is seeing a little random use.

If this is intended as a test of disk longetivity it's useless as the numbers are far to small to get a viable result. I'd say that you need a couple of thousand disks, preferably different models from different manufacturers, to be able to make any generally applicable guidelines.

So do I on my most used NAS that is equipped with enterprise disks. On my backup server that have desktop disks and that over long periods only is used nightly I do let them spin down.
