NAS is writing every 5 seconds

[Sir.Robin]

The recent days i've noticed that my primary NAS (9.2.1p1 and 9.2.1.p2) is writing to disk all the time, even when no clients are doing anything.

gstat shows the activity.

I have nothing going on, but still... every (about) 5 seconds it writes to the pool.
Tryed to disable CIFS to be sure, but the writing continoue.

What is it doing? Shouldn't it be idle when there is no client activity?

I'd drop into IRC and ask one of the developers about this. I'd be interested to see the answer myself...

 

[Sir.Robin]

Errh... do you mean you will do that? :)

Not sure if this has been going on before on earlier versions. Just noticed. Also, this is occuring on my secondary aswell.

 

[cyberjock]

I'm on 9.2.0 and I don't have that problem.. so *I* can't do that. That's why I said you should go to IRC and see if a developer will help. If you show up in the IRC I'll see if I can get someone's attention though.. I'm in the IRC more often than not.

 

[Sir.Robin]

I'm in :)

So i got answer on this from jkh on irc. The writing is because Syslog is moved to the system dataset. This can be turned off. :)

 

[cyberjock]

Ah! That makes sense! Thanks for finding out!

You forgot to mention HOW you turn it off. :)
Unticking the "Use system dataset for syslog" option will suffice? Thanks for your findings, let me know.

 

[Sir.Robin]

Sorry!

Yes, untick "Use system dataset for syslog" under System - Advanced.

Then i did a reboot and all activity seized on my pool. :)

Thanks for that.
And now syslog is writing on my OS usb stick all the time? How does this worked in the past?

 

[Sir.Robin]

Well it worked out fine. Although the USB sticks aren't made for a lot of writing... like SSD's.

How long it will last i don't know but i did not want the constant disk rattle myself.
Besides... my FreeNAS is a VM not running on a USB stick.

Although i most likely would have done the same if it were. :)

the syslogs write to a ramdisk normally and not to the USB stick. Don't let the location of the logs fool you, it's really a ramdisk copy of the USB stick.

Now that is good to know too.
