NUT package (2.8.0 and below)

w0w · Dec 23, 2016, 4:36 AM

Concerning scripts work around it may be usb root hub device power off and power on with usbconfig.
Something similar to

— turn off

usbconfig -d 0.1 set_config 255

— turn on

usbconfig -d 0.1 set_config 0

0.1 is device address on root hub, ex. ugen0.1

This should reset device connection as it happening on PC reboot.

Thank you for analysis.

1 - Unfortunately at this moment it is not possible; this year I bayed this UPS and can't return it any more, it have 2 years warranty but I am sure seller/manufacturer will not fix this problem. To buy another one here in Poland will be a game of chance as seller & manufacturer don't publish full spec. On log term plan I am thinking it will be better to buy an inverter.
2 - No.
3 - I can replace the driver only if you can post the driver patched as I don't have a working FreeBSD 10.3 development environment to do the build.
4 - Not possible for the moment the other computers around are win that are scheduled to turn off overnight and also I don't have a monitor program for win.
5 - Yes, for the moment I just returned to scheduled cron script that restart NUT every 15 min… any help is appreciated.

thank you

p.s.
w0w unfortunately your suggestion don't work:
usbconfig -d 5.2 set_config 255 - it kill the communication but;
usbconfig -d 5.2 set_config 0 - can't restore the communication, not even NUT restart will fix it and I have to unplug the USB cable to fix the communication.

w0w · Dec 23, 2016, 11:59 AM

I am sorry, my bad, instead of powering off and on your device just try to do this with root hub where is your ups is connected.
Do
usbconfig | grep ugen5
You should see something like
ugen5.1: <uhci root="" hub="" intel="">at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE
ugen5.2: <usb to="" serial="" inno="" tech="">at usbus5, cfg=255 md=HOST spd=LOW (1.5Mbps) pwr=ON (100mA)
So try
usbconfig -d 5.1 set_config 255
usbconfig -d 5.1 set_config 0
and see what happening.</usb></uhci>

n3by · Dec 23, 2016, 12:24 PM

I tested:
communication is not restored automatically after power on the USB hub, it still required to restart the NUT service.

edit.

Thank you.

I like the idea to power OFF-ON the USB HUB so I added to nut_restart script:

#!/bin/sh

/usr/local/etc/rc.d/nut.sh stop
usbconfig -d 5.1 set_config 255
sleep 30
usbconfig -d 5.1 set_config 0
sleep 30
/usr/local/etc/rc.d/nut.sh start

@n3by:

4 - Not possible for the moment the other computers around are win that are scheduled to turn off overnight and also I don't have a monitor program for win.

Maybe you could utilize a RPi-Linux at 3W power ?

n3by · Dec 23, 2016, 1:54 PM

Sorry I have no RPI here in Poland… and to buy now rpi3+memory+case+power here is ~90 $...

Instead restarting NUT in sheduled fashion, just use script below to check if upsc fails to connect ups and then restart everything you want.
When UPS driver connection is lost, run
upsc -l
It gives you your configured UPS name, run
upsc "upsname"
without quotes

remember the output, you will need it below in pattern variable. Just put it in quotes like it is.
for example if upsc myhomeups gives you output
connection unavailable
then change script line to

pattern="connection unavailable"

#!/bin/sh
# Script to restart NUT and USB UPS if UPS connection failed
upsname=$(upsc -l)
pattern="failed UPS message from upsc"
check=$(upsc $upsname | grep -o "$pattern")
if [ "$check" = "$pattern" ] ;
then
/usr/local/etc/rc.d/nut.sh stop
usbconfig -d 5.1 set_config 255
sleep 30
usbconfig -d 5.1 set_config 0
sleep 30
/usr/local/etc/rc.d/nut.sh start
fi

You can use cron to schedule script for every 3 minutes for example, or even less if you tune down your sleep timers.

n3by · Dec 23, 2016, 8:14 PM

This is what I did:

because this is normal output if communication with UPS is working OK:

upsc ActiveJet

battery.charge.low: 50

driver.parameter.runtimecal: 180,100,320,50
driver.parameter.synchronous: no

driver.version.internal: 0.12

input.voltage.fault: 241.2
output.voltage: 241.2
ups.beeper.status: enabled
ups.delay.shutdown: 30
ups.delay.start: 180
ups.load: 19
ups.productid: 5161
ups.status: OL
ups.type: offline / line interactive
ups.vendorid: 0665

I changed your script to this one:

#!/bin/sh

Script to restart NUT and USB UPS if UPS connection failed on ActiveJet

upsname="ActiveJet"
pattern="battery.charge:"
check=$(upsc $upsname | grep -o "$pattern")
if [ "$check" != "$pattern" ]; then
/usr/local/etc/rc.d/nut.sh stop

usbconfig -d 5.1 set_config 255

sleep 10

usbconfig -d 5.1 set_config 0

sleep 5
/usr/local/etc/rc.d/nut.sh start
fi

and I added to cron to run it every 3 min.

If you have a better suggestion please share.

Thank you again !

edit:
changed the script and cron from 2 to 3 and now to 4 min because something is not ok and it restart to often.

n3by · Dec 23, 2016, 8:55 PM

strange … If I did not made a mistake I think the script interfere with normal NUT because it will restart almost every time.
Maybe we can look in syslog for last NUT error messages and not try to interrogate NUT ??

Remove any other scripts you have put in place and replace /usr/local/etc/rc.d/nut.sh with the script below. I would not add any USB configuration commands unless you encounter a situation in which the script does not restart the driver. If you do encounter such a situation, please run "usbconfig dump_device_desc" while the problem is happening and post the result.

Note that the nut.sh script is automatically written every time the NUT configuration is saved This will happen anytime you change the UPS config or upgrade pfSense. When this happens, just copy this script back in place.

I would keep the setting of "pollinterval = 10" in the ups.conf advanced section as this will significantly reduce the number of occurrences of driver failure. No other advanced settings are needed.

Regarding the other settings you were doing:


default.battery.voltage.high = 13.7
default.battery.voltage.low = 11.5
runtimecal = 180,100,360,50
ignorelb
override.battery.charge.low = 50
override.battery.runtime.low = 600

These are actually arguments to the UPS driver rather than global directives. As such, they should be in the (non-advanced) section entitled "Extra Arguments to driver" rather than in the advanced section.

You should have nothing in the advanced section other than the pollinterval setting in ups.conf.

Hope this works out for you.

That looks like kill is missing the -0.

Just to confirm the script is correct, could you run a sum on it please?

sum /usr/local/etc/rc.d/nut.sh

The result should be 60215.

#!/bin/sh
# Script to restart NUT and USB UPS if UPS connection failed
upsname=$(upsc -l)

fi

For me even if I change upsname=$(upsc -l) directly to ups name it works just fine and NEVER gives me message "NUT must be restarted". If your UPS does not answer to every query, then it is the root cause of the script behavior. You should manually test script, running this several times, looking for the answer.

edit:

only pid I have in /var/db/nut:
blazer_usb-ActiveJet.pid
upsmon.pid
upsd.pid

I try to use script with blazer_usb-ActiveJet.pid

edit2:

now it looks ok, will see in time how is doing.
thank you.

Did you stop the service before putting the new script in place? If not, the old script may still be running.

The command to stop the script is:

/usr/local/etc/rc.d/nut.sh stop

After doing so, the following commands should find no processes:
ps -axuw | grep ups
ps -axuw | grep nut
ps -axuw | grep blazer

If that isn't the issue, please run the debug version below by hand. The command to do this is:

/usr/local/etc/rc.d/nut.sh start

Make sure the service is stopped before you start the debug script. Also understand that it will continue to product output even after the command prompt returns. To stop it, you again would execute:

/usr/local/etc/rc.d/nut.sh stop

Please let it run for a minute or two and post the output from the terminal. I'll have a look at it in the morning.

dennypage just to let you know that your script is working great until now, and I made your changes in nut.inc so it will survive a reboot or UPS parameter changes till package upgrade/reinstall.

In case anybody else will need it; just make the appropriate changes for you in the line with "blazer_usb-ActiveJet.pid";
you can find your "driver_usb-upsname.pid" in /var/db/nut/ when NUT is running…

credit go to dennypage !

part with changes I made in:
/usr/local/pkg/nut/nut.inc

function nut_write_rcfile($driver) {
	nut_check_var_db();
	$start .= "echo starting NUT";
	$start .= "\n	if [ -f /var/run/upsdrvctl_loop.pid ]";
	$start .= "\n	then";
	$start .= "\n		kill -9 `cat /var/db/nut/upsdrvctl_loop.pid`";
	$start .= "\n		rm /var/run/upsdrvctl_loop.pid";
	$start .= "\n	fi";
	$start .= "\n	/usr/bin/killall -q -9 upsmon";
	$start .= "\n	/usr/bin/killall -q -9 upsd";
	$start .= "\n	/usr/bin/killall -q -9 upsdrvctl";
	if (isset($driver)) {
		$start .= "\n	/usr/bin/killall -q -9 $driver";
	}

	/* Service status keys off upsmon, so start it first. */
	$start .= "\n	/usr/local/sbin/upsmon";
	if (isset($driver)) {
		$start .= "\n	/usr/local/sbin/upsdrvctl start &";
		$start .= "\n	(";
		$start .= "\n		while true";
		$start .= "\n		do";
		$start .= "\n			sleep 15";
		$start .= "\n			kill -0 `cat /var/db/nut/blazer_usb-ActiveJet.pid` > /dev/null 2>&1 && continue";
		$start .= "\n			/usr/local/sbin/upsdrvctl start";
		$start .= "\n		done";
		$start .= "\n	) &";
		$start .= "\n	echo $! > /var/db/nut/upsdrvctl_loop.pid";
		/* Since we are starting the driver in backgroud, give it a moment to start. */
		$start .= "\n	sleep 1";
		$start .= "\n	/usr/local/sbin/upsd -u root";
	}
	$start .= "\n	return 0";

	$stop .= "echo stopping NUT";
	$stop .= "\n	if [ -f /var/db/nut/upsdrvctl_loop.pid ]";
	$stop .= "\n	then";
	$stop .= "\n		kill -9 `cat /var/db/nut/upsdrvctl_loop.pid`";
	$stop .= "\n		rm /var/db/nut/upsdrvctl_loop.pid";
	$stop .= "\n	fi";
	$stop .= "\n	/usr/bin/killall -q upsmon";
	if (isset($driver)) {
		$stop .= "\n	/usr/bin/killall -q upsd";
		$stop .= "\n	/usr/bin/killall -q upsdrvctl";
		$stop .= "\n	/usr/bin/killall -q $driver";
	}
	$stop .= "\n	return 0";

	write_rcfile(array(
		"file" => "nut.sh",
		"start" => $start,
		"stop" => $stop
		)
	);

Thank you very much for help to all that got involved to solve this/my problem !
and
Merry Christmas !

@n3by:

you can find your "driver_usb-upsname.pid" in /var/db/nut/ when NUT is running…

I forgot about the ups name in the pid file. It had to be something stupid.

On the system I was testing on the ups is named "ups" and the driver name is "usbhid-ups". This results in a pid file named "usbhid-ups-ups.pid". I think I'll change the name of the ups to prevent this sort of mistake in the future. :)
