Re: [Nut-upsuser] Ubuntu server won't restart

I'm quite stuck now so any pointers on how to troubleshoot is most  
appreciated.


The first thing to check is whether or not the UPS receives the  
shutdown command. Power your system from an alternative source (this  
is important!) and run the command


/path/to/usbhid-ups -k -a UPS

This signals the UPS to cycle the output (if mains is present) or  
shutdown the output and wait for the power to return (if not). Look at  
the console for messages that are displayed.


If the above works (both with and without mains present), there  
probably is an issue with running this command late in the system halt  
script. This is something the people from Ubuntu should be able to  
help you with. If it doesn't work, come back here for more help.


Best regards, Arjen

This worked as expected although it took about 60 sec for the UPS to 
power off. The server had plenty of time to shutdown gracefully.


I examined the /etc/init.d/ups-monitor script (which is called from 
/etc/init.d/halt) and I noticed a reference to a POWEROFF_WAIT statement 
in /etc/default/nut. If present, the ups-monitor script waits the 
specified amount of time for the UPS to power down. If it doesn't, 
ups-monitor reboots the server.


So I added POWEROFF_WAIT = 75 and now everything seems to work fine.

Is this an appropriate way of solving this?

Again, thanks for your help!

Kind regards
/Erik
