Arjen, Thanks for your very tutorial email. It helped a lot. I have moved my master monitor to the nfs machine and setup upsmon on all other machines.

They did. The halt shutdown script includes code that runs /etc/init.d/ups-monitor poweroff if $INIT_HALT = POWEROFF, which is controlled by /etc/default/halt. There, default setting is HALT=poweroff So it should all work. > [...] In order to be able to restart if the power returns in > the mean time, 'ondelay' must be higher than 'offdelay'. I have two variables that I can set: 1) ups.delay.shutdown: Interval to wait after shutdown with delay command (seconds) 2) ups.delay.start: Interval to wait before (re)starting the load (seconds) I set 1 to 30 on both UPS and 2 to 60 on the master and 180 on the slave, so that the master (nfs server) is avaiable before the rest comes back. Unfortunately, there doesn't seem to be a variable that controls how much charge the UPS must have before switching the load back on - I suppose, it doesn't care. I'm pretty confident though that both UPSes have enough charge to go through a second reboot and shutdown cycle even if they're starting on 50%, which is what I have configured to be the critical point. Now all I have to do is wait for the next thunderstorm :) Cheers, Tom _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
