Re: [Nut-upsuser] upsmon shutdown based on Time since power fail.

2009-05-25 Thread Arjen de Korte

Citeren Richard Chapman :

This sounds like one way to do it. If I do it this way - do you know  
whether the file:


/etc/killpower

will be created before the shut-down is issued (as it would if the  
battery low event occurs). If not - the UPS may not be shut down -  
and therefore the system may not start up again if the power returns  
before the battery is completely flat.


I guess if the flag file isn't created - then we could run a short  
script to create it - then issue the shut-down Does that sound  
right to you? Indeed - if we do write a short script - we could do  
the delay in the script - somehow test whether we are still on  
battery - and if so - issue the shut-down immediately.


Don't do this. As written in the FAQ, in some cases you may wish/need  
to use 'upssched' to start shutting down your systems before the UPS  
indicates the battery is low. In that case, you probably want to call  
'upsmon -c fsd' instead, which will initiate a shutdown on the upsmon  
master (in your case, your server). This means that you will have to  
configure the upsmon on the server (FINALDELAY) to allow for enough  
time for your clients to shutdown. This will put your master at risk  
in case of repeated power failures however, so don't overdo this.


Best regards, Arjen

Hi

I am sorry, but i can not answer any of your technical NUT questions,  
i just wrote with an idea that might or might not work.


As for starting the machine if power returns, then i can think of some  
remote power management that can turn the power on/off to the machine  
and then sit between the UPS and the machine(s). WAKE on LAN might be  
an option too.

Out of interest - do you know what the ups parameter:

battery.runtime: 120

Means - and where might it be documented?

Is there another parameter somewhere - probably in upsmon - which  
would allow me to specify a shut-down after (say) 3 minutes  
running on battery regardless of battery status?


In the upsmon.conf file you use NOTIFYCMD and ONBATT to execute a  
shutdown $time


Then you use a ONLINE to execute a -c to cancel a shutdown if the  
power returns.
