I'm running an APC UPS on Gentoo linux (Back-UPS XS 1300G). Up till now, I've used the UPS in "dumb" mode; i.e. no acpusd running. My main concern has been short power blips, and under/over-voltage. All I wanted was a few minutes to shut down or hibernate the PC before the battery gave out. I've enabled the "Master/Controlled outlets" feature. I have the PC plugged into the Master, and a surgeprotector powerbar into a Controlled outlet. The monitor/speakers/modem/etc are plugged into the surgeprotector. When I manually hibernate the PC, the ups cuts off power to the peripherals connected to the surgeprotector (connected to the "Controlled outlet").
I may be getting a contract soon that involves crunching huge text files, with multi-hour overnight data runs, etc. I'll launch a run, and leave things unattended for hours on end. Let's assume I start a run, go away for the day, and a power outage hits. My Google searches always seem to turn up hits involving sending warning messages to users that the system may be going down soon. What I actually want to happen in an extended power outage is... * have the system execute the command "/usr/sbin/hibernate" to save program state, etc to disk, and then shut down. * shut down the APC ups afterwards. Note that once "/usr/sbin/hibernate" is launched, you have to assume that the ups immediately loses contact with the PC, ***BUT THE UPS MUST STAY ON FOR A COUPLE OF MINUTES AFTERWARD*** to give the PC time to shut down gracefully. Will "KILLDELAY 180" give 3 minutes safety margin? And what do I have to do to get it to execute "/usr/sbin/hibernate"? As per instructions from the install, I've done... rc-update add apcupsd.powerfail shutdown ...which is supposed to tell the ups to shut down when the PC shuts down. Colour me confused... * does the ups not shut itself down due to BATTERYLEVEL/MINUTES/TIMEOUT? * if so, why does it need the "apcupsd.powerfail" service in my PC's shutdown runlevel?
