Hi desbma,

since I updated my host OS to Ubuntu 20.10 hddfancontrol is no longer spinning down my harddisks.
(Dockerfile: https://github.com/fightforlife/docker_hddfancontrol/blob/313b51ce636978750240eb0e002f43edf50d2c4b/Dockerfile)

The log does not show any errors.
Manual spindown with hdparm -y works just fine. And the drives stay spun down. (in host OS and inside docker)

Is there some way to get more output?

I checked with dstat if the drives are accesses somehow.
But the only activity I can see is the temperature query of hddfancontrol every 60seconds, which results in a read of about 1536B.

Temperature query should not generate a block read. Are you sure nothing else is active on the drive?

If you stop hddfancontrol and run for example: cat /sys/block/sdX/stat && sleep 60s && cat /sys/block/sdX/stat (replace sdX with your drive) do the numbers change?

here some logging from my system. I am not entirely sure if maybe this is correct behaviour. I did not test this before updating ubuntu (and kernel).
I always see this in the hddfancontrol logs, which suggests that something is accessing the disk every 60 seconds.
DEBUG [DriveSpinDownThread-sdd WDC WD15EADS-00S2B0] Sleeping for 60 seconds

If I change the intervall of hddfancontrol to -i 30 the message stays the same.

Another note:
If I put the drives manually to standby it is correctly reflected in the hddfancontrol logs and the fans are turned off.
Also the drives are not woken by hddfancontrol.

What about: sudo bash -c 'cat /sys/block/sdd/stat && hddtemp /dev/sdd && cat /sys/block/sdd/stat' ?

If you did not have hddfancontrol running while executing sudo bash -c 'cat /sys/block/sdd/stat && hddtemp /dev/sdd && cat /sys/block/sdd/stat' and had that output, it means something is generating periodic disk reads which would prevent the drive from spinning down.

That something can either be:

  • hddtemp itself, in that case you are doomed because hddfancontrol uses it to probe temperature, so your drives will never spin down. That is very unlikely though, because hddtemp is abandoned, hasn't changed in years, and it usually sends a special command to the drive and does need to read any disk block.
  • something else on your system. You can try to find it by using sudo iotop -o -d 60 but that command does not filter by device, so that could generate a lot of noise. There may be some other tools better suited to investigate this, but nothing comes to mind.

In the comment above I entered the commands around every 5 seconds. That's why it looks like periodic. I can provide such a spike with every hddtemp or smartctl request.
The last btrace command (with hddfancontrol running) shows access by hddtemp.
The btrace command before that shows access by smartctl.

So my guess is not that something changed in smartctl or hddtemp, but in the way /sys/block/*/stat works.

I will try to investigate this further.

I am currently using https://github.com/docker-hotio/docker-hd-idle for spindown instead of hddfancontrol and it is working fine.
After multiple tests I am a hundred percent sure that the following commands are causing the small read spikes.

hddtemp /dev/sd*
smartctl -a /dev/sd* | grep Temp | cut -d" " -f 2,37

There were some changes in the block layer between kernel 5.4 to 5.8. but I currently cannot say if this could be a cause.

  • diskstats: more accurate io_ticks and optimization
  • Add iostat counters for flush requests

Indeed my main NAS is also on Arch, and the 5.10 LTS kernel update broke the auto spin down.

If anyone has an idea on how to probe for disk activity by evading the hddtemp/smartctl interferences, I'm open to new approaches, until then there is not much I can do to fix this.

Fix released in version 1.4.0.

Inactive drives should be properly detected, unless smartctl is used for temperature probing (not the default) and SCT temp query is not supported.

Does anyone know if this issue is handled upstream somewhere? I did not test the workaround, yet. Unfortunately, I monitor the system temps with smartctl which also prevents the drive spindown with more recent kernels. Downgraded to 5.4 for now :(

desbma commented Mar 9, 2021

@mindrunner
It should work fine if hddfancontrol is probing temperature with any of the following methods:

  • with hddtemp invocation (the default)
  • with hddtemp daemon query
  • with hdparm invocation (your drive needs to support it)
  • withsmartctl -l scttempsts /dev/sdX invocation (your drive needs to support it)

In those cases, probing generates a fixed and predictable (in my experience with an admittedly limited amount of drive models) number of read operations, so hddfancontrol can count the number of temp probes, the expected counter difference, and so detect drive inactivity reliably.
However if you explicitly choose to use smartctl for probing AND your drive does not support SCT temp probing, then all SMART attributes are read to try to extract temperature and that generates a highly variable number of read operations depending on the exact drive model, which makes hddfancontrol unable to reliably detect drive activity/inactivity, and trigger spin down accordingly.

mindrunner commented Mar 22, 2021

Thanks for the detailed information. On top of hddfancontrol I am regularly running some scripts, probing drive temperature, idle state and smart data from the drives for monitoring purposes.

Before the kernel update, this was working fine in combination with hddfancontrol. (drives spinning down). Will running those scripts prevent hddfancontrol spinning down the drives now?

I know, this is sort of off topic for hddfancontrol. But I really consider that as a bug/regression, since it was perfectly fine before. Does anyone know which part of the kernel is responsible for this? Maybe we can continue the discussion over there?

It should be related to the block layer. You can try to contact the maintainers of that part of the kernel, and/or try to track the commit that caused this change. I personally don't have enough time to do this, but I'd be curious to learn the rationale for the change.

I was browsing the kernel bugzilla yesterday, but could not find anything helpful. I guess I would need to bisect the kernel sources to figure out.
In adelolmo/hd-idle#38 someone suggests, to use partitions instead of device names to query activity to get around this issue. Would it be possible to run hddfancontrol with HDDFANCONTROL_ARGS="-d /dev/sda1 /dev/sdb1" instead of HDDFANCONTROL_ARGS="-d /dev/sda /dev/sdb"? Or does that not make any sense?

Stat counters are per block device in the kernel, not per partition, and probing the partition device will probe the same device in effect, so I don't think that could allow you to work around this issue.

That would be the way to go, if you can automate the test to check if a commit is affected or not. You are also more likely to get attention from a kernel developer if you have precise information about the commit that caused the regression.

Looking at https://github.com/adelolmo, I cannot confirm your statement. The most recent version is able to detect my drives being idle on most recent kernel versions despite hddfancontrol and other periodic smartctl checks are enabled. Unfortunately, hddfancontrol is not able to spin down the drives on my system. So for now I need both hddfancontrol for controlling the hdd-fans and hd-idle for the disk spin-down when idle.

desbma commented Apr 6, 2021

You are right and I was wrong, there are indeed per partition counters, and temperature probing affects only the device counters.

However passing partitions can be confusing because it can lead to spinning down a drive that is currently active on another partition.
I guess supporting partitions, but printing a warning would be a good compromise.

The safest way to test without affecting the rest of your system would be:

git clone https://github.com/desbma/hddfancontrol/  ~/hddfancontrol
cd ~/hddfancontrol
pip3 install -r requirements.txt
python3 setup.py install
sudo ~/venv-hddfancontrol/bin/hddfancontrol ...

Once you are done, you can remove ~/venv-hddfancontrol and ~/hddfancontrol, nothing else has been changed on your system.

indeed spins down the drives after 20 minutes, whereas

sudo ~/venv-hddfancontrol/bin/hddfancontrol -d /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf -p /sys/class/hwmon/hwmon3/device/pwm2 /sys/class/hwmon/hwmon3/device/pwm3 --pwm-start-value 89 89 --pwm-stop-value 84 84 --min-fan-speed-prct 0 -i 60 --min-temp 35 --max-temp 70 --spin-down-time 1800

does not. So it definitely makes a difference and would solve the issue

Probably worth adding that to the readme ;)

I could add that to the REAME... just as I could explain how to install Python, partition a hard drive or buy a computer. These instructions are nothing specific to this project.

Anyway thanks for confirming the fix, I will make a new release soon.

In many years I spend a lot of time in figuring out how to build and run projects I am supposed to work on w/o having the proper documentation. IMHO, documentation is same important as clean and readable code and having a how-to section for a newbie developer on how to get started is a very very nice thing to have, even if it is as straight forward as it is in this case.

Just my 2 cents.

Thanks for fixing.

@mindrunner I agree with you doc is important that is why there is a section in the README on how to install from source.

The snippet I gave you is how to install hddfancontrol as non root, alongside an existing installation. There is no way I can document every single possible installation use case, especially if this is nothing specific to this project, which by the way targets technical users.

Technology works by stacking solutions and hiding complexity behind abstractions. This project relies on Python, Linux, x86, and probably thousands of stuff I don't even know of. It is not feasible to document everything.

ha, I was pretty sure I checked and didn't see any instructions. Thus, my question about how to install from source... My bad! Sorry for the misunderstanding :)
