UPS, Ubuntu 18.04 - help needed

[xrapidx]

I'm running Ubuntu 18.04 on my docker server.

I recently moved said server to where my NAS is - and put them on the same UPS - initially, the UPS (APC) was connected directly to the NAS, which allowed the UPS to trigger a shutdown event on the NAS when power is low. (Buffalo TeraStation - fairly locked down, but I got SSH access and can trigger a shutdown)

Now - I'd like to connect to the UPS to the server, and somehow trigger a shutdown from the server when power is low for both the server, and the NAS - what's going to be my best approach?

Ive also got to figure out how to start the NAS/Server backup after power restores.

Server and NAS should have settings in the BIOS to auto start when it detects power. My gaming PC has this function.



Im sure the NAS/server should do this automatically because if not then whats the point of a server. Unless your server isnt an actual server but rather a Home PC with server software?

Yeh, it is a server (HP Gen8 Microserver) - it does have the functionality - not sure about the NAS though, if its been shutdown remotely - whether it'll start up again

Under /etc/apcupsd you have various scripts. One of them is called "onbattery". You can use this to trigger a shutdown of other systems when this system goes on battery.

You could possible use WOL (wake on lan) to start up the other systems from system that monitor the UPS.
"etherwake" could be used to wake up other systems. WOL will have to enabled in their BIOS.

Starting up automatically is normally only with a power failure not a shutdown.
Also, if you shutdown the system, the UPS will probably still have enough power to make it seem that there is power, so no "power restore" event will be detected.

That's what I suspect - although the NAS seemed to handle it automatically, but I think it was built into their "handling" software with the UPS.

I'd like to try and test this all and get it working while I'm at home - so I don't run into a situation where I'm away and my whole house stops working.

Just ran into another problem - realised the switches aren't on the UPS... going to have to make a "UPS multiplug for the UPS + Servers + office switch"

And it looks like the battery is dying/dead good day for this project.
