Proper power off

1st Official Post

    So I understand it's not ideal to just pull the plug on an RPi so I'm trying to make sure that LibreELEC get's shutdown cleanly. I have been playing with getting a UPS working on it and setting it up to automatically shut down when power is removed (The unit I'm using is a LiFePO4wered/Pi3).

    Problem is when I remove the power and it shuts it down (after two minutes) I frequently see that when I plug power back in the unit doesn't ever get to the KODI boot screen just the first LibreELEC one. I then have to pull the power throughout the system, after which it reboots just fine.

    I have to be able to remove power from the system as it's going to live in a motorhome and may have it's power interuppted at anytime, I have the source for the daemon for the LiFePO4wered so I can mod it but I don't know what to call. It looks like from looking at the source it does this:

    Code
    void shutdown(void) { syslog(LOG_INFO, "LiFePO4wered/Pi triggered shutdown"); char *params[3] = {"init", "0", NULL}; execv("/sbin/init", params); }

    Sounds like it's not shutting down properly.
    You'll need to provide a LOT more information. How are you running the daemon, what is the full code, can you confirm it has shut down completely.

    What do the logs say?

    Personally, I think you'd be better off just powering the RPi off of the motorhome's 12/24V battery power supply (With a converter). Should be able to power the RPi for weeks!

    Okay I'll go grab logs, I think my real question is what command would I issue from a SSH prompt and expect a good clean shutdown it looks like thi sis using "init 0" I can link you to the full code for the dameon here: GitHub - xorbit/LiFePO4wered-Pi: Access library, command line tool and daemon for the LiFePO4wered/Pi module

    I've thought about running it off the 12V, but I don't want it just powering up randomly, I'm particularly sensitive about the use of any power in the rig as we boondock a lot (no external power). Also since there's a hard disk associated with it I don't want that spinning all the time. I also want this to be somewhat spouse proof. So it would be best if it just worked like another consumer component (i.e. the DVD player it's all replacing)

    Thanks, again though will that signal kodi to do a clean shutdown, or is there some other thing I need to do to ensure that kodi comes down cleanly.

    I ave found this for LibreElec/kodi :

    - Edit the lifepo4wered-daemon.c file and change the shutdown function to this:

    void shutdown(void) {
    syslog(LOG_INFO, "LiFePO4wered/Pi triggered shutdown");
    char *params[6] = {"shutdown", "-h", "-t", "60", "now", NULL}; // shutdown halt in 10 seconds
    execv("/sbin/shutdown", params);
    }

    Thank you for posting I actually knew about that, it's exactly what I was asking about is that the correct way to clean shutdown Kodi...
