Hello all,
I've got an MGE Pulsar Ellipse Premium 800 powering a couple of FreeBSD
systems. Driver used is mge-shut, I don't know what the new mge-shut
driver offers, but I follow the "if it works, don't fix it" dogma here. :)
I also had a nut server installed on the master, with the
/usr/local/etc/rc.d/nut script slightly modified to include a couple of
upsrw commands in order to power off ups and also to delay ups start-up:
gw[/root]# diff nut.mod nut.orig
34d33
< stop_precmd="nut_prestop"
41,50d39
< nut_prestop() {
< if (test -f /etc/killpower) then
< rm /etc/killpower
< sleep 5
< echo "Ordering UPS to delay-shutdown."
< ${nut_prefix}/bin/upsrw -s ups.delay.shutdown=80 -u user -p pass
mailfw@localhost
< ${nut_prefix}/bin/upsrw -s ups.delay.start=15 -u user -p pass
mailfw@localhost
< fi
< }
<
This script worked just fine for a number of years. Yesterday, while
looking the syslogs after a power failure, I saw that during the
nut-initiated shutdown procedure (notice the "Ordering UPS to
delay-shutdown" message) errors were logged, most likely due to these
two commands:
Jun 24 19:28:37 mail upslog[858]: Signal 15: exiting
Jun 24 19:28:37 mail kernel: .
Jun 24 19:28:37 mail kernel: Stopping nut_upslog.
Jun 24 19:28:42 mail kernel: Ordering UPS to delay-shutdown.
Jun 24 19:28:42 mail kernel: Unexpected response from upsd: ERR
VAR-NOT-SUPPORTED
Jun 24 19:28:42 mail kernel: Unexpected response from upsd: ERR
VAR-NOT-SUPPORTED
So my question is, have these commands changed? From the output of upsrw
below, most likely ups.delay.shutdown and ups.delay.start have been
replaced by ups.timer.shutdown and ups.timer.start. Is that correct, are
these phrasal changes only?
For the record:
