查看完整版本 : Fancontrol according to hard disk temperature 使 Linux 根據硬碟溫度控制風扇轉速

Thanks to “路寅甲”, I got a simple script to control fan speed according to hard drive temperature via [b][color=Blue][url=https://pkgs.org/download/fancontrol]Fancontrol[/url][/color][/b], [b][color=Blue][url=https://pkgs.org/download/hddtemp]Hddtemp[/url][/color][/b], and [b][color=Blue][url=https://www.archlinux.org/packages/?name=lm_sensors]Lm-sensors[/url][/color][/b]. In the following script, “[b][color=Red]/dev/sda[/color][/b]” is the hard disk to be monitored, and “[b][color=Red]/Fancontrol/Hddtemp[/color][/b]” is the output file to be read by Fancontrol. Press [b][color=Red]Ctrl[/color] + [color=Red]Alt[/color] + [color=Red]T[/color][/b] to open Terminal and run the following command to check whether “[b][color=Red]/dev/sda[/color][/b]” is the correct one:[code]sudo hddtemp /dev/sd[a-z][/code]Use only the one supported by Hddtemp, which will display the temperature rather than “S.M.A.R.T. not available”.
Replace “[b][color=Red]/dev/sda[/color][/b]” with the correct one in the script if necessary.
If you have not yet configured Fancontrol, see [b][color=Blue][url=https://wiki.archlinux.org/index.php/fan_speed_control]this page[/url][/color][/b], [b][color=Blue][url=https://askubuntu.com/questions/22108/]this page[/url][/color][/b], and [b][color=Blue][url=http://tuxtweaks.com/2008/08/how-to-control-fan-speeds-in-ubuntu/]this page[/url][/color][/b] and run the following commands one by one (restart Linux after running the first one):

[b][color=#ff0000]sudo sensors-detect  
watch sensors
sudo pwmconfig
sudo service fancontrol start[/color][/b]

Then, go through the procedure below:
(1) Run the following command to create a script file.
[b][color=Red]sudo mkdir -p "/Fancontrol/" & sudo xed /Fancontrol/HDD_temp[/color][/b]
[color=#ff0000][/color](2) Copy the following script into the file and save it.

[b][color=#ff0000]#!/bin/bash[/color][/b]
[b][color=#ff0000]F=/Fancontrol/Hddtemp[/color][/b]
[b][color=#ff0000]while true[/color][/b]
[b][color=#ff0000]do [/color][/b]
[b][color=#ff0000]T=$(sudo hddtemp -n /dev/sda)[/color][/b]
[b][color=#ff0000]echo $(($T * 1000)) > "$F"[/color][/b]
[b][color=#ff0000]sleep 30 [/color][/b]
[b][color=#ff0000]done[/color][/b]

(3) Run the following command to make it executable.
[color=#ff0000][b]sudo chmod +x /Fancontrol/HDD_temp[/b][/color]
[color=#ff0000][/color](4) Run the following command to create a service file.
[b][color=Red]sudo xed /lib/systemd/system/HDD_temp.service[/color][/b]
[color=#ff0000][/color](5) Copy the following lines into the file and save it.

[b][color=#ff0000][Service][/color][/b]
[b][color=#ff0000]ExecStart=/Fancontrol/HDD_temp

[Install]
WantedBy=multi-user.target[/color][/b]

(6) Run the following commands one by one:
[b][color=Red]sudo chmod 664 /lib/systemd/system/HDD_temp.service
sudo systemctl daemon-reload
sudo systemctl start HDD_temp.service
sudo systemctl enable HDD_temp.service [/color][/b]

Then, the script “[b][color=Red]HDD_temp[/color][/b]” will be run as a system service at Linux startup.
(7) Run the following command to edit “[b][color=Red]fancontrol[/color][/b]”, the configuration file.
[b][color=Red]sudo xed /etc/fancontrol[/color][/b]

Find the line that begins with “[b][color=Red]FCTEMPS[/color][/b]”. For example:
[b][color=Red]FCTEMPS=hwmon1/pwm1=hwmon1/temp1_input[/color][/b]

On that line, [b][color=Red]hwmon1/temp1_input[/color][/b] is the temperature (e.g. the chipset temperature) currently read by Fancontrol. Replace it with [b][color=Red]/Fancontrol/Hddtemp[/color][/b], and the line will become:
[b][color=Red]FCTEMPS=hwmon1/pwm1=/Fancontrol/Hddtemp[/color][/b]

Save the file and run the following command to restart Fancontrol.
[b][color=Red]sudo service fancontrol restart[/color][/b]

Then, the fan controlled by “[b][color=Red]hwmon1/pwm1[/color][/b]” will respond to “[b][color=Red]/Fancontrol/Hddtemp[/color][/b]”, the hard disk temperature. Note that "HDD_temp" and "Hddtemp" are the script file and output file respectively. Don't confuse them.

UNIX script開頭要有#!, 以指定執行script的程式, 例如bash


script應放在PATH指定的Folder, /var/lib/不在PATH內, 且根據script內容睇, LOCATION=/var/lib/Fancontrol_Hddtemp是個directory, 並非script本身, 是用作記錄HDD溫度, 給fancontrol daemon參考


如要在啟動系統時自動執行該script, 另外要寫個systemd service file, 然後行systemctl enable <file>

睇清maximum係指最高溫嗰隻disk, 所以拉出while loop係錯
要原來咁每個loop清零，留返係while裡面

Assuming "~/folder/HDD_temp" is the path to the script, how should I create such a file? The script has to be run before Fancontrol is started. Otherwise, Fancontrol has to be restarted. [/quote]

簡單起見, 我將個script同fancontrol package放埋一齊,  /usr/sbin/fancontrol-via-hddtemp

boot機時自動執行shell script嘅方法可參考
[url=https://linuxconfig.org/how-to-automatically-execute-shell-script-at-startup-boot-on-systemd-linux]https://linuxconfig.org/how-to-automatically-execute-shell-script-at-startup-boot-on-systemd-linux[/url]


係呢個case, 因為安裝fancontrol時已帶有systemd unit file, 可以試作為參考, (同上邊條link擺放unit file嘅direcoty不同, 無問題)

1. 睇 fancontrol 的 systemd unit file ( cat /lib/systemd/system/fancontrol.service )

[Unit]
Description=fan speed regulator
# Run pwmconfig to create this file.
ConditionPathExists=/etc/fancontrol
After=lm-sensors.service
Documentation=man:fancontrol(8) man:pwmconfig(8)

[Service]
ExecStartPre=/usr/sbin/fancontrol --check
ExecStart=/usr/sbin/fancontrol
PIDFile=/var/run/fancontrol.pid

[Install]
WantedBy=multi-user.target

2. 複製並修改做 /lib/systemd/system/fancontrol-via-hddtemp.service  

[Unit]
Description=fan speed regulator via hdd temp
After=lm-sensors.service
Before=fancontrol.service

[Service]
ExecStart=/usr/sbin/fancontrol-via-hddtemp
PIDFile=/var/run/fancontrol-via-hddtemp.pid

[Install]
WantedBy=multi-user.target

完成後好似上邊條link講咁reload systemd daemon ...
# systemctl daemon-reload
# systemctl enable fancontrol-via-hddtemp.service
# reboot

#通常係bash prompt最後一個字母, 後面跟住嘅係正式command, 入command唔使#

所以第4個唔係command, 係第3個command執行後顯示嘅結果

第一句command如果個file係從其它service file複製出嚟再修改就唔使, 如果放係/lib/systemd/systm/內, 應跟返其它文件用644權限

第3個command你打漏咗enable :
   systemctl enable fancontrol-via-hddtemp.service

The script will output "maximum".
When one HDD is connected, the output is 40000, which is normal.
When two HDDs are connected, the output is 1600000, which is impossible.

我試咗插隻USB然後run個script係正常,
USB本身冇sensor, 但獲取溫度嘅指令會彈出一句
   [okla@host ~]$ hddtemp -n /dev/sdd 2>/dev/null
   /dev/sdd: Generic STORAGE DEVICE: S.M.A.R.T. not available
for loop會一個個詞咁check, 如果呢個output包含有數字, 就會被當作溫度處理, 出現錯誤結果

可試解決辦法是讓for loop將hddtemp輸出指令成個一齊check係唔係數字,
將separator定義為"new line", 而並非預定嘅"space"

/dev/sdd: Generic STORAGE DEVICE: S.M.A.R.T. not available

個command係script內用作獲取HDD溫度, 如果你部機出唔到, 硬件有問題?

若只想用sda溫度, 將DISKS改下, 其餘部份雖有多餘coding, 可留以後有慢慢研究

DISKS="/dev/sda"

或將while loop簡化下,


while true
    do
    temperature=$(hddtemp -n /dev/sda 2>/dev/null)
    [[ $temperature != [0-9]* ]] && continue
    # fancontrol output format
    echo "($temperature * 1000)/1" | bc > "$FILE_MAX".write
    mv --force "$FILE_MAX".write "$FILE_MAX"
    sleep 45
done
