I hope you can help me.
I have two servers running OMV 4. One is connected to a UPS (and using the UPS plugin will shutdown during a power failure) and I would like the ability to shut down the second server automatically in the event of power loss.
I was thinking of running the openmediavault-autoshutdown addon on the second server, have it check for when server one powers off then run the autoshutdown plugin.
I have an issue though. Server 2 is based on arm (helios4) and I have read the autoshutdown plugin doesn't work.
Can I get some guidance on how to do this any other way?
I was thinking of having a script run on server 2, pinging server 1 at regular intervals. If server 1 is off then shutdown server 2. It's a bit crude but I think this might work.
Has anyone done anything like this or can I get an example?
