xu4-cloudshell2-fancontrol with RAID monitoring

This is a fork from xu4-cloudshell2-fancontrol that was modified/combined with a script to display RAID Info and HDD Temperatures (modified from this). It is possible to set temperature thresholds for CPU and HDD where the fan will be turned on. Note that this is mainly a mere combination of different authors' work!

Notes

• this script was tested on Odroid Cloudshell 2 with XU4
• my RAID is encrypted and mounted to /dev/mapper/secure: in case you have multiple Harddrives, you may have to modify the reference to Harddrives for Temperature monitoring
• you can manually enable/disable the lcd-script by executing systemctl stop cloudshell-lcd and systemctl start cloudshell-lcd

Installation

• follow these steps to install the original lcd-service from Odroid, e.g.:

  odroid@odroid:~$ sudo apt-get update
  odroid@odroid:~$ sudo apt-get install odroid-cloudshell cloudshell2-fan
  odroid@odroid:~$ sudo reboot

  (here is the link to the current script)
• overwrite the /bin/cloudshell-lcd and /bin/checkRAID.bash/ with the content in this repo
• add the following line to crontab (crontab -e): 0,15,30,45 * * * * /bin/checkRAID.bash > /bin/checkRAID.txt 2>&1
• optionally, edit the file cloudshell-lcd.service in /lib/systemd/system and add two lines in [Service] section:

ExecStart=/bin/cloudshell-lcd
ExecStopPost=/usr/sbin/i2cset -y 1 0x60 0x05 0x00

This will enable the fan whenever the cloudshell-lcd.service stops. To prevent the fan to be enabled on system-shutdown, it is also necessary to copy the file shutdown-fan to /lib/systemd/system-shutdown/
