Hi,
I had a stable NUT environment for quite a while until I had to change UPS
and reinstalled my Proxmox environment.
I had a backup of my /etc/nut directory and have only used it as reference.
My UPS is a Powerwalker VI 2200 IEC/UK and that corresponded to
*usbhid-ups*.
*nut-scanner -U* returns the following
Cannot load SNMP library (libnetsnmp.so.40) : file not found. SNMP search
disabled.
Cannot load XML library (libneon.so.27) : file not found. XML search
disabled.
Cannot load IPMI library (libfreeipmi.so.17) : file not found. IPMI search
disabled.
Scanning USB bus.
[nutdev1]
driver = "nutdrv_qx"
port = "auto"
vendorid = "0665"
productid = "5161"
product = "USB to Serial"
serial = "20100826"
vendor = "INNO TECH"
bus = "001"
device = "003"
busport = "003"
###NOTMATCHED-YET###bcdDevice = "0002"
The three *Cannot load* errors are not present in my notes and I suspect
they could be the root cause of successive errors.
My */etc/nut/ups.conf* is as follows:
# Wait 10 seconds for the driver to finish starting.
maxstartdelay = 10
# Try 3 times to start the driver, before giving up.
maxretry = 3
# Wait 5 seconds between attempts to start the driver.
retrydelay = 5
# Poll the ups every 5 seconds
pollinterval = 5
[pve1]
# PowerWalker
driver = usbhid-ups
port = auto
desc = "Cypress Semiconductor USB to Serial"
vendorid = 0665
productid = 5161
# if the charge is less than 75 percent trigger a LB status
override.battery.charge.low = 75
# Some drivers reset battery.charge.low. lowbatt addresses this
lowbatt = 75
# if the remaining charge is less than 1200s (20 minutes) trigger a low
battery status
override.battery.runtime.low = 1200
# Wait 10 minutes before attempting to restart the ups load after a power
cut
ondelay = 600
# wait 5 minutes for ups to power off
override.ups.delay.shutdown = 300
# Could offdelay act as an override for override.ups.delay.shutdown?
offdelay = 300
serial = 20100826
When I execute *upsdrvctl start* I get the following repeated 3 times
Network UPS Tools - UPS driver controller 2.8.1
Network UPS Tools - Generic HID driver 0.52 (2.8.1)
USB communication driver (libusb 1.0) 0.46
libusb1: Could not open any HID devices: insufficient permissions on
everything
No matching HID UPS found
upsnotify: notify about state 4 with libsystemd: was requested, but not
running as a service unit now, will not spam more about it
upsnotify: failed to notify about state 4: no notification tech defined,
will not spam more about it
Driver failed to start (exit status=1)
Thanks,
Alan
