NUT package (2.8.0 and below)

It is a problem of user rights ?

No.

This are the settings I have:

upsmon.conf

DEADTIME 30
POLLFREQ 10
POLLFREQALERT 10
SHUTDOWNCMD "/sbin/halt -p"

ups.conf

pollinterval = 10
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

attached img with usbconfig after error, before I unplugged the cable.

@n3by:

Any ideas why is not working properly custom-upssched-cmd ?

And since you are probably are still thinking about this… yes, because your UPS is going offline for longer than it takes to restart the NUT service.

This cannot be your ups.conf as there is no actual ups definition. Please do not edit files by hand. Go into the UPS configuration (Services / UPS / Settings), remove everything from the advanced section except for "pollinterval=10", and save the configuration. This is where we will start.

Please post the contents of cat /usr/local/etc/nut/ups.conf, /usr/local/etc/nut/upsmon.conf, and /usr/local/etc/nut/upsd.conf for confirmation.

I have this config because I wanted the firewall to shutdown quick ( ~1-2 min ) if power is lost and not when UPS will send battery low.
I also have another computer - file server on this ups that monitor by a script I made if firewall is ON => UPS is online; other way will shut down ( it ping LAN interface ).

All this because I can power ON all this computers by IAMT - remote but this require UPS to be ON; if battery is empty then UPS will go OFF and will stay OFF even if main power will restore.

With this 2 computers normal running on UPS I have a load of ~20% ( 90w ) so plenty of time for UPS to stay ON when power is lost and this 2 computers will also quick power OFF.

I made a small change increasing timer to 60s in upssched.conf and changed

custom-upssched-cmd

#!/bin/sh
NAME=`basename $0`
LOGGER="/usr/bin/logger -t $NAME"

case $1 in
	ups-no-comm)
		$LOGGER "Timer event '$1' fired, restart NUT..."
		/usr/local/etc/rc.d/nut.sh stop
		sleep 30
		/usr/local/etc/rc.d/nut.sh start
        ;;
    *)
        $LOGGER "Unrecognized command: '$1'"

I understand what you are trying to do, however your current configuration does not actually do this. Most of the configuration is in the wrong place. It is unfortunate that NUT generally ignores invalid configuration rather than generating an error. Anyway, save this stuff for later–it's just creating complication in diagnosing the issue.

If you want help you will need to listen and stop changing things willy-nilly. Stop messing around with upssched.conf. Stop messing around with the advanced settings. Remove everything in the advanced section except "pollinterval=10" in the ups.conf section. Don't edit any files by hand.

If you don't want help, that's okay too. I won't be offended at all. Really.

Okay. When the problem next occurs, please do the following:

1. Grab system log entries from Status / System Logs / System / General. Logs at the time of the event and the preceding few minutes. Plus any log entries with "usb" "ups" or "nut" since startup even if not near the event.
2. Log in and run "usbconfig dump_device_desc".
3. Attempt restart of the UPS service (Status / Services).
4. If #3 does not bring the service back, unplug the host end of the USB cable for 10 seconds, then attempt service restart again.
5. If #3 and #4 do not bring the service back, run usbconfig again, and then reboot.

Please post the results.

Btw, you can remove your SHUTDOWNCMD from the advanced settings as well. It does the same thing as the default shutdown command but without notice. No advantage to this.

p.s.
it looks like upssched is not executed at all because it not stop the service, and this is wrong.
I need a script that will restart the UPS service, only if communication with UPS is lost and upsched is not doing this at the moment.

Dec 22 06:21:18 firewall1 blazer_usb[5521]: Permissions problem: Input/output error

Pretty sure I know what the problem is. Going to take a bit of research to find out if there is a work-around.

dennypage

Here's my analysis. Short version: You have a flakey UPS and are also encountering a kernel bug.

The UPS is using an inbuilt Cypress 1.0 USB to serial chip (vendor 0x0665 product 0x5161). What kicks the problem off is that the chip flakes out briefly. This appears to be a pretty well known issue with this chip.

When this happens at the wrong moment, it triggers a bug in the FreeBSD kernel. The kernel gets confused. It's one of those "this should never happen" bugs. When it does happen, it triggers a safety check that causes EPERM (not permitted) to be returned in response to a read or write operations on the USB device. The error value EPERM is incorrect. It should return EIO or ENXIO.

The NUT Blazer driver (or Qx driver) would correctly handle EIO or ENXIO, and attempt close/reopen the device. However the driver interprets EPERM for any USB command to be a fatal error, causing the driver to exit. One could argue that the NUT driver could be changed to treat EPERM the same as ENXIO for FreeBSD, but this would create problems with driver when there are actual permission problems. And it really isn't their bug.

I don't have a device that produces this behavior, so I cannot effectively debug the root cause of the kernel issue. The best I can do is to submit a patch to the FreeBSD folk to change the return value from the safety check, which I will do. However I expect that it will take a long time for this change to make its way into a released kernel.

In the interim, several choices come to mind:

1. Get a new UPS. Something that doesn't use the old Cypress USB chip.
2. Build a custom kernel to use with pfSense. This is a very bad idea, and I mention it for completeness only.
3. Build a custom version of the NUT Blazer driver. If you want to do this, let me know and I will send you a patch that will work around the problem. You will need a working FreeBSD 10.3 development environment to do the build.
4. Move the UPS to another host (non FreeBSD), and use NUT's remote monitoring feature from pfSense.
5. Try to work around it with scripts. This approach is fine as long as there isn't a power failure. If the problem happens in close proximity to a power failure, this may well result in failure of the shutdown function.

Option #1 is your best bet. If you can't do that, then I would look at #4. I don't know what your other hosts are, but if one is a Linux box that you can run NUT on, this is a good way to go. If you cannot do #1 or #4, let me know and I can suggest an alternate approach for #5.

Sorry to not have better news to offer.

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.

ugen5.2: <usb to="" serial="" inno="" tech="">at usbus5, cfg=255 md=HOST spd=LOW (1.5Mbps) pwr=ON (100mA)

bLength = 0x0012

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>

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

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.

This is what I did:

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

upsc ActiveJet

battery.charge.low: 50
battery.runtime: 714
battery.runtime.low: 600
battery.voltage: 13.70
battery.voltage.high: 13.7
battery.voltage.low: 12

driver.parameter.synchronous: no

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.
