Easy fix fan/temp issues on OS6 legacy #no support

[yupsolo]

Hi,

I'm on Os 6 from Os 4 on my ultra2.

By now I've got trouble getting logged via SSH. Yes it's enable but keep kicking me out after login.



I would love to fix the temp-fan issue...



Anything that I,m missing?

Anyone got into the same trouble?


Thx for helping!

thx...


I did'nt recall this one!


it's working

I have applied the fan fix to my Pro6 running 6.1.1 but the fan keeps powering up and down almost constantly. I took it to another location and it was fine, so it's sensing the temperature in it's normal location is too hot, and is powering the fans to keep the CPU at a constant temperature I think.

The problem is from the UI I can't see what the CPU real time temps are so I can determine how to tweak my profile to adjust accordingly.

How can I see what my temps are for real?

Optimal Fan Setting for an Ultra2


after many days of testing+many settings here's what I find are the best:


55
60
45
45
45
155

it keep the fan very quiet but with high airflow so, the CPU barely reach 55 celcius.


glad if it can help cuz for me it was a long road of testing!

I assume that your numbers are MinTemp, MaxTemp, MinStart, MinStop, MinPWM, MaxPWM. If so, how did you come up with MinPWM=45? And more importantly, why did you limit MaxPWM to 155? That seems dangerous.

[yupsolo]

maxPWM was chosen by me to ensure minimal fan noise with good max speed versus my real average temp number: 54-55 celcius for over a week.... so it does not bother me.


45 seems ideal cuz with greater number, the fan was, again, too noisy. so with 45, i get 54-55 celcius without that noisy fan pattern: low speed-fast speed-low-fast...


in short, the fan is running all the time at 1350 wich is my magic number: quiet!


🙂


believe me I spent a lot of hours on that.

On my legacy Ultra2 I had false CPU temp readings exactly like drfrgosplat (serrated, like a wood saw, saying the cpu went up close to 70°C degrees).
Then I upgraded from 6.1.1 to 6.1.2 and I noticed an nice improvement in the CPU temperature reading that doesn't cause anymore the fan to ramp up to it's 2200rpm maximum (this is not documented in the release notes ; understandable if it didn't occur on ReadyNAS 3xx/5xx).

The inconsistent noise level was really annoying!! So I am now a happy OS6 user :woot:

PS: I didn't had to apply any command line fix for the temp reading neither fan speed the fan.

Anyone able to offer any assistance? My fans are going so loud every 10-20 seconds or so.

Hi everyone!

I just updated my Ultra 6 from 6.0.8 to 6.1.2 and suddenly started getting fan alerts.
The OS6 GUI says my fan is dead. However, I can hear & see it blowing, and running "sensors" gives me the following output:

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +47.0°C  (high = +80.0°C, crit = +100.0°C)

it8721-isa-0a10

in7:          +3.29 V  (min =  +3.38 V, max =  +1.46 V)  ALARM
in8:          +3.38 V
fan1:           0 RPM  (min =   16 RPM)  ALARM
fan2:           0 RPM  (min =   30 RPM)  ALARM
fan3:         866 RPM  (min =   15 RPM)
temp1:         +0.0°C  (low  = +71.0°C, high = -20.0°C)  ALARM  sensor = thermistor
temp2:         +0.1°C  (low  = +122.0°C, high = +59.0°C)  sensor = thermal diode
temp3:         +0.1°C  (low  =  -1.0°C, high =  -6.0°C)  ALARM  sensor = thermal diode
cpu0_vid:    +2.050 V

So the fan is actually running fine.

/etc/fancontrol looks like this:

Kernel:

I don't have any shell scripts running with a cron job though.
Should I have some script running to have my RN report correct fan status?

TIA!

OS 6 reads fan1 speed, but unfortunately it's pwm3 file which control fan on ultra 6 system....
Since 6.1.1, on ultra 6, OS 6 reports 0 rpm as fan speed and send an alert mail every 10 minutes about fan error ....

Add a sensors.d config file to compute 0+800 rpm on fan1, and OS 6 reports 800 rpm on GUI . It's not really good, but fan error disapears !

Add this file rndu6000.conf in /etc/sensors.d and reboot your nas :

chip "it8721-isa-0a10"

    compute fan1 @+800,@-800

Another thing: OS6 reads /sys/devices/platform/it87.2576/temp2_input as sys temp.... unfortunately, on ultra 6 sys temp is temp1

**** EDIT **** better solution to solve this problem and activate reports and history on frontview : viewtopic.php?f=51&t=71155&start=60#p411650

[revin]

I've installed OS6 on a pro2. As I don't have fan speed and CPU temp, I've made a small script to generate my own RRD.

First, we have to generate the cpu RRD and Temp RRD. I've created on /dashboard/frontview/stats/

rrdtool create fan.rrd --step 60 \
DS:rpm:GAUGE:120:0:5000 \
RRA:AVERAGE:0,5:1:2880 \
RRA:AVERAGE:0,5:30:384 \
RRA:AVERAGE:0,5:120:384 \
RRA:AVERAGE:0,5:1440:365 \
RRA:MAX:0,5:1:2880 \
RRA:MAX:0,5:30:384 \
RRA:MAX:0,5:120:384 \
RRA:MAX:0,5:1440:365 \
RRA:MIN:0,5:1:2880 \
RRA:MIN:0,5:30:384 \
RRA:MIN:0,5:120:384 \

and now CPU RRD:

rrdtool create temp_sys.rrd --step 60 \
DS:core0:GAUGE:120:0:100 \
DS:core1:GAUGE:120:0:100 \
DS:system:GAUGE:120:0:100 \
RRA:AVERAGE:0,5:1:2880 \
RRA:AVERAGE:0,5:30:384 \
RRA:AVERAGE:0,5:120:384 \
RRA:AVERAGE:0,5:1440:365 \
RRA:MAX:0,5:1:2880 \
RRA:MAX:0,5:30:384 \
RRA:MAX:0,5:120:384 \
RRA:MAX:0,5:1440:365 \
RRA:MIN:0,5:1:2880 \
RRA:MIN:0,5:30:384 \
RRA:MIN:0,5:120:384 \

Now it's time to create a script (update_rdd). This script gets temperature from CPU Core 0, CPU Core 1, System temperature and fan speed and updates de RRDs

#!/bin/sh
#####################################################
Coretemp1="/sys/devices/platform/coretemp.0/temp2_input"
Coretemp2="/sys/devices/platform/coretemp.0/temp3_input"
Systemp="/sys/devices/platform/it87.2576/temp2_input"
fan="/sys/devices/platform/it87.2576/fan1_input"
F=`cat $fan`
C1t=`cat $Coretemp1`
C1=`expr $C1t / 1000`
C2t=`cat $Coretemp2`
C2=`expr $C2t / 1000`
S=`cat $Systemp`
rrdtool update /frontview/dashboard/stats/temp_sys.rrd N:$C1:$C2:$S
rrdtool update /frontview/dashboard/stats/fan.rrd N:$F
##echo " CPU1=$C1 CPU2=$C2 SYS=$S "

So, We have the data on RRD. Now It's time to draw!. This example creates 2 simple PNGs from "now - 4 hours"

rrdtool graph /frontview/dashboard/stats/tempsys.png --title="Temperature" --start end-4h \
        --imgformat=PNG \

        COMMENT:"Comments"

The last step it's call those scripts from crontab:

*/1 *   * * *   root /root/scripts/update_rrd
*/2 *   * * *   root /root/scripts/print_rrd

I've tried to change the images from original dashboard with this ones but it was much easier to generate a simple HTML and call this PNGs 😎

WOW revin! Your post above looks pretty cool. Any chance we could get a glimpse of your "Performance Tab" after you performed this hack? I'd be interested to see if I could do something similar on a Pro 6. . .

[revin]

ATCIS,

My images are really crapy :D. Here are an example:






But you really can make them as you want, simply playing a bit with rddtool graph (http://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html)

Here you have a few examples about what can you do with rrdtool : http://oss.oetiker.ch/rrdtool/gallery/

Is this fix still needed for the Ultra series?
I just upgraded and my fans/temp seems be ok. At least they are recognized in the dashboard.
Fan running a bit slow atm though (820 rpm)
CPU is 59/138 and System 44/111

System is idle except for re-sync

Hi all,

I've just upgraded my Ultra 6 to 6.1.4. & having fan issues. i've followed all the instruction in the threads, but it doesn't work at all for me.
i've installed the lm-sensors & fancontrol, but giving me this error

Any idea guys? i'm very desperate & my Ultra 6 fan now running on max 2300rpm. 😞

Please help me. Thanks in advance

[MueR]

I'll post my fancontrol config tonight (if I remember, I'm terrible at those things). It should work for you, but if the device is idle, frontview will report the CPU at -1°C / 30°F.

F.L.: which Ultra do you own? I own an Ultra 6 and my fan still isn't recognized in the web UI ("fan dead" message).

I own an Ultra 4. Fan is still working here without any modification

[sventunus]

Are you running a custom fancontrol/lm-sensors config? Would you care to post it here?
Curious about the difference between an Ultra 4 & an Ultra 6 concerning fans.
Thanks!

[F_L_]

Nothing custom. I just upgraded to 6.1.4 and it was working out of the box.

If you still want any config please let me know where they are located.

[giovannip]

I'm running in a similar behaviour on my Ultra 6 upgraded to 6.1.4. the fan slow down when I run /etc/init.d/fancontrol start but after few minutes I get a warning on hdds temperature:

Thu Nov 7 2013 23:34:23	Disk: Disk in channel '5' (Internal) exceeded safe temperature threshold (70 C).

and after few minutes the Nas shutdown automatically.

Any suggestion ?

Here my /etc/fancontrol file

You can try to upgrade a little bit the fan speed.
Test 45 or 50 as fan speed. Change this lines in fancontrol file:

MINSTART= hwmon1/device/pwm3=50
MINSTOP= hwmon1/device/pwm3=50
MINPWM= hwmon1/device/pwm3=50

[giovannip]

Hi glem,

thanks for the help, I did set 50 but unfortunatly after 1 hour the hdd temperature went close to 70°C again 😞

OS 6.x on it8721 chip use fan1 sensor to drive enclosure fan and temp2 sensor to monitor enclosure temperature (this configuration works fine on Ultra2 model, for example).

Unfortunately, ultra6 model use fan3 and temp1 sensors.
To activate reports and history on frontview on ultra6 model running OS 6.x, you must add this sensors.d config file to compute the correct values:

in /etc/sensors.d add this file rndu6000.conf

chip "it8721-isa-0a10"

compute fan1 0+fan3_input,0-fan3_input
compute temp2 0+temp1_input,0-temp1_input

and restart your ultra6 NAS
