TS-251/TS-451 HDD Spindown on 4.2.2

Post by Undergrid » Sat Aug 20, 2016 4:03 am

Since an upgrade to 4.2.2 from an earlier version of QTS (I'm not sure the version) I've had a problem with the HDDs on both of my NAS's not spinning down properly. Using blkdevMonitor.sh I tracked this down to setcfg dirtying log file inodes.

This was odd, because nothing was using the UI and it seemed to be happening every ten mins or so. Then I found this in crontab:

Code: Select all

0-59/10 * * * * /etc/init.d/storage_usage.sh


Looking at the code, it repeatedly calls setcfg to (as far as I can tell) update storage usage (volumes, pools and iscsi). Isn't this a pretty fatal flaw in the OS design? From what I can tell, hard drives are never going to spin down unless you set a time of less than 10 mins and then they'll just spin up again in a few mins...

Interesting.
I have 3 QNAPs all updated to 4.2.2
My 119 has always spun down and still does.
My 453 has never spun down and still don't.
My 251 I do not know, because it does not have any HDD LED's .....

Then, I'm uncertain as to the actual benefit of HDD spindown (?). Some people say that the tear and wear on HDD's are far greater during start than for continuous run. So, I guess if a NAS actually serve some purpose (doing jobs), it will spin up frequently anyway, right? In large datasenters, drives spin 24/7/365 everywhere.
Perhaps letting them spin all the time is best?
(P.S. my 119 spin down is OK, because it is not doing anything for the time being.)

Hi Undergrid,

it's my third Qnap Nas.
Every time i made a firmware update on them, the spin down function will move from effective to not effective or reverse.
Since moving my 239 pro 2+ from 4.2.1 to 4.2.2 the HDD spin down function will not work anymore.

Welcome to qnap.

NB/ i don't use any function of the nas despite raid, microsoft network and upnp discovery

I have the same issue...
In QTS 4.2.2 my TS-212P wake up by process cryptsetup every 8-10 minutes.
Went back to QTS 4.2.1 (20160601) all is working fine. Now my Qnap goes to sleep.

Same issue here....TS-451, updating to QTS 4.2.2 killed spindown & sleep for me.

Back down to 4.2.1 and working fine again.

I have the same on the 21/10 4.4.2 firmware on my TS-251.

Update: I have just downgraded to previously, 20160901-4.2.2, version, and now the drives spins down as expected.

I have the same problem, created a ticket with QNAP and nothing has happened. How do I downgrade the firmware?

Thanks for this! Was having the same issues on my TS-251+, rolling back to 20160901-4.2.2 has allowed it to hibernate again.

Hello all, I came across the same problem on my TVS-473 with the latest 4.3.3.0154 Build 20170413. Currently having the unit connected to TV in the living room. I use the NAS occasionally either running VMs or streaming various multimedia. Besides these activities I would expect the unit to sleep :) although QNAP did good job in keeping low noise of this unit, it is still low noise that is annoying when there is complete silence. For now I do not want to move the NAS to other room as HDMI connectivity to TV is preferred to me.

As I googled through many forum topics I found out using blkdevMonitor.sh that setcfg executes every 10 minutes and prevents the unit from sleep. This topic led me to explore crontab where
0-59/10 * * * * /etc/init.d/storage_usage.sh
executes every ten minutes. As pointed out by Undergrid this seems to me as design flaw too. What is the purpose of running storage_usage.sh every 10 mins? what happens if I remove storage_usage.sh from crontab? can this interval be change lets say from 10mins to 12hrs? :S

thx

I took the line out and experienced no negative side effects. As of 4.3.3.0154 at least my HDD2 in my 253 is sleeping again.

Thx for insight. I'll give it a shot as well. Anyone from QNAP team can comment on this idea?
