Today I noticed NUT wasn't running. Said it couldn't be started. See the SYSLOG below. I selected the 2.8.4 backend in the NUT settings as suggested by @NoRaid99, rebooted my server, and now it's working again. No idea what's wrong with 2.8.5. I'm still on unraid 6.12.13.

Might be very simple, but how do I enabled beeping? I found: but I cannot find the mentioned username/password anywhere...

Thanks for the swift reply! I believe copy syslog to flash on shutdown was enabled already, but it seemed that the copying didn't actually happen before the unclean shutdown. Like I mentioned, this morning I moved the USB cable between the UPS and server to another port (USB 3.2 vs 2.0 if that matters) and I haven't had a single error since then (no messages about low batteries either except for a single one right after starting NUT, in fact). Perhaps the port was the problem...

Yes, of course! Attached it. nut-debug-20240409133951.zip

I have an issue with the current version (NUT 2.8.2) running on my server. I've recently connected an APC BX1600MI-GR and I've been getting error messages and two unclean/unexpected shutdowns resulting in a parity check so far. At the time of the first shutdown I was running powertop --auto-tune which had enabled the USB autosuspend. I haven't run --auto-tune since rebooting and I've also enabled the USB power management override option in NUT. I was still getting the following errors and eventually the second shutdown: Apr 7 18:53:59 Tower usbhid-ups[3860]: nut_libusb_get_report: Input/Output Error Apr 7 18:54:01 Tower usbhid-ups[3860]: #012Reconnecting. If you saw "nut_libusb_get_interrupt: Input/Output Error" or similar message in the log above, try setting "pollonly" flag in "ups.conf" options section for this driver! So after rebooting I enabled the GUI settings override option, added pollonly = "enabled" to ups.conf, and restarted NUT. Now I was getting the following error messages in the syslog: Apr 9 02:38:08 Tower usbhid-ups[21630]: nut_libusb_get_report: Input/Output Error Apr 9 03:43:05 Tower usbhid-ups[21630]: nut_libusb_get_report: Input/Output Error Apr 9 04:02:17 Tower usbhid-ups[21630]: nut_libusb_get_report: Input/Output Error Apr 9 04:02:17 Tower kernel: usb 1-11: USB disconnect, device number 7 Apr 9 04:02:17 Tower usbhid-ups[21630]: libusb1: Could not open any HID devices: insufficient permissions on everything Apr 9 04:02:17 Tower upsd[21675]: Data for UPS [ups] is stale - check driver Apr 9 04:02:18 Tower upsmon[21678]: Poll UPS [[email protected]] failed - Data stale Apr 9 04:02:18 Tower upsmon[21678]: Communications with UPS [email protected] lost Apr 9 04:02:18 Tower kernel: usb 1-11: new low-speed USB device number 8 using xhci_hcd Apr 9 04:02:18 Tower kernel: hid-generic 0003:051D:0002.0006: hiddev96,hidraw0: USB HID v1.10 Device [American Power Conversion Back-UPS BX1600MI] on usb-0000:00:14.0-11/input0 Apr 9 04:02:19 Tower upsd[21675]: UPS [ups] data is no longer stale Apr 9 04:02:23 Tower upsmon[21678]: Communications with UPS [email protected] established Apr 9 04:28:17 Tower usbhid-ups[21630]: nut_libusb_get_report: Input/Output Error Apr 9 04:54:29 Tower usbhid-ups[21630]: nut_libusb_get_report: Input/Output Error Apr 9 04:56:41 Tower usbhid-ups[21630]: nut_libusb_get_report: Input/Output Error I've since switched the cable to another USB port (this morning) and haven't had an error since then (just over an hour ago). I've attached the full syslog and NUT USB diagnostics if that helps. Anyone who has an idea on what's going on? syslog.txt UPS USB diags.txt

That's a bummer, I'll try NUT when I get home. For now I guess I'll just leave the UPS USB-cable unplugged. Thanks anyway! Posted in the github issue too.

I'm running Unraid 6.12.8 and I've hooked up my APC BX1600MI-GR UPS yesterday but am running into an issue. I noticed this morning that my server had shut down overnight, and is now running a parity check. I found that rather strange as it's never happened before I connected the UPS. Looking at the System log I can see that the battery is constantly showing as disconnected/reattached, even though the info on the UPS settings page looks perfectly fine. Any idea what's going on here? I suspect this has something to do with the server shutting down overnight. Thanks!

Hi, I've set up an Unraid server a couple weeks back and got around to setting up powertop as well. I installed it through the NerdTools plugin. I've got the following system: - ASUS TUF GAMING B560M-PLUS - i5-11600K - 2x Lexar NM710 2TB - 2x Exos X20 18TB (spins down after 15 mins idle) - A single fan on the bequiet pure rock 2 (the on included) These are the relevant BIOS settings (I think) I've set up: Intel Adaptive Boost Technology: Disabled ASUS Performance Enhancement 2.0: Disabled GPU Boost: Keep Current Settings PCI Express Native Power Management: Enabled Native ASPM: Enabled DMI Link ASPM Control: L1 ASPM: L0sL1 L1 Substrates: L1.1 & L1.2 DMI Gen3 ASPM Control: ASPM L1 (The BIOS says that "L0s is not supported for DMI Aspm for CML/TGP", no idea what that means...) DMI Gen3 ASPM: ASPM L1 (Same BIOS comment about CML/TGP here...) PEG - ASPM: L0sL1 PCI Express Clock Gating: Enabled Intel SpeedStep: Enabled Intel Speed Shift Technology: Disabled Turbo Mode: Disabled CPU C-States: Enabled Enhanced C-States: Enabled CPU C6 Report: Enabled CPU C7 Report: CPU C7 CPU C8 Report: Enabled CPU C9 Report: Enabled CPU C10 Report: Enabled Package C-State Limit: C10 CFG Lock: Disabled Thermal Monitor: Enabled Dual Tau Boost: Disabled SATA Mode Selection: AHCI (I have disabled all SATA ports except for 1 and 3 that have the drives attached) Aggressive LPM Support: Enabled Network Stack: Disabled HD Audio: Disabled Realtek LAN Controller: Enabled USB Power delivery in Soft Off State (S5): Disabled LED lighting when system is in working state: Stealth Mode: All LEDs will be disabled Max Power Saving: Enabled ErP Ready: Enable (S4+S5) Power on by PCI-E: Disabled Power on by RTC: Disabled CPU Fan Profile: Silent. I then ran powertop --autotune resulting in the data at the bottom of this post (lspci output at the very bottom in case it's useful). C3 is the highest C-state I can reach. Idle power consumption is now around 23W. Is there any way I can get this lower? Thanks!
