See notes for details.įor remote hosts only. A command that will be executed to obtain the temperatures of this remote system. See below for details.įor remote hosts only. See below for details.Ī list of three speeds (in %) at which fans will run for the correspondent threshold. Prevents rapid speed changes, a good starting value can be 3.Ī list of three upper bounds (in ☌) of temperature thresholds. How many degrees (in ☌) the CPUs' temperature must go below the threshold to trigger slowing the fans down. How often (in seconds) to read the CPUs' temperatures and adjust the fans' speeds. Toggle debug mode (print ipmitools commands instead of executing them, enable additional logging). Remote hosts must also contain both the remote_temperature_command string and the remote_ipmi_credentials structure. If the hysteresis key isn't specified, its value is assumed to be 0. Each of them must contain a temperatures and a speeds lists at a minimum, both of exactly three values. The first one contains global options the second one, hosts, is a list of hosts to manage. The file is made of two main sections, general and hosts.

You can tune the controller's settings via the fan_control.yaml file in the installation directory. If a configuration file already exists, it will be renamed with a. That's why I'd suggest pulling them and not putting them back until you feel the system is ready to function.The default installation path is /opt/fan_control and the service will be installed as rvice. Probably your worst case scenarios are that 'mucking about' with the broken system you end up wiping the config data out from the physical disks.

If I felt that the RAID controller was in question, and that the contents of the array were highly valuable I would do something like this:
