Liebert GXT4 on Proxmox won't shutdown

[EmnaX]

Hello, I am having some issues with an Emerson Liebert GXT4 connected to a Supermicro server running Proxmox VE 7.1-11. NUT was installed using apt. NUT is able to report UPS status properly and safely shutdown Proxmox; however, the UPS never kills power to the outlets so the batteries slowly drain during a power outage. It seems the upsdrvctl shutdown command fails for some reason. I have copied as much info below as I can think of. Any idea what might be causing the issue?

When I first installed NUT, the driver couldn't take over /dev/bus/usb/005/004 so I had to create a udev rule which fixed the issue. I found an example online that I copied. Before adding the udev rule, /dev/bus/usb/005/004 was owned by root:root.

# My udev rule

I'm just a passerby but from my understanding

    override.battery.charge.warning = 60
    override.battery.charge.low = 50

despite the assertive name, these override things don't actually override the behaviour at the UPS, they just fake the numbers you give so they are what is read back by nut. This is what you want for, eg, wrong info coming back from the ups for number of batteries or whatever.

To change the variables inside the UPS itself, you're supposed to use upsrw. But I am also struggling with what I am setting that way not being told to the UPS itself.

[EmnaX]

Thanks for stopping by Andy!

I have had good luck with those two variables actually working on this Liebert GXT4 as well as a couple Cyber Power UPS models that I have. I believe you also need to add the ignorelb line for those two overrides to work. When I was doing my testing to ensure the UPS would shut everything down properly, I had the following overrides set:

    ignorelb
    override.battery.charge.warning = 98
    override.battery.charge.low = 95

As soon as the UPS display showed the battery charge drop to 94%, Proxmox initiated the shutdown procedure.

Now, I can't seem to figure out how to turn off the UPS after everything shuts down but hopefully someone smarter then I can spot my issue.

[jimklimov]

Just in case, could you try with a recent NUT github master build? There were some Liebert related PRs since 2.7.4 release, I think, maybe some impacted your use-case.

Proxmox is based on Debian and is capable of building NUT "natively" (got one hosting parts of NUT CI in fact).

[EmnaX]

Thanks for the suggestion Jim. I have not built anything from source before so I'll have to figure that out. It looks like there is some great documentation over here: https://networkupstools.org/docs/user-manual.chunked/ar01s05.html#Installing_source

I'll give that a shot and report back.

[EmnaX]

Ok, here is the follow up. I wasn't sure exactly what I was doing so I made a Debian VM so I didn't mess something up in Proxmox. I passed through the UPS for testing. I get a seg fault now when running the usbhid-ups -DDDDD -a ups1 -k command.

Not sure what that means but maybe this is causing the issue?

[jimklimov]

Thanks for the report, the segmentation fault is not good, and I found where it was, posting a fix. If you are not comfortable with git, in drivers/usbhid-ups.c file there is an instcmd() method. It logs "using Path" just before checking if (hidups_item == NULL) to try other commands - and it is this logging that can crash; removing the line should help for this bit of the issue.

I am not really sure about the "interface 0" part, except that in recent year's work there were PRs to allow use of "not only 0" interface for composite USB devices, and some context from discussions about that.

[jimklimov]

Note: Sources indicate at https://github.com/networkupstools/nut/blob/master/drivers/belkin-hid.c#L524 that for this subdriver the shutdown.return support was not detected/completed during development (might be missing in hardware), so they suggested a power-drain as the way to turn off the UPS and have it return when wall power returns, as documented in belkinunv manpage.

I guess it would need some forensics from you with the scripts/subdriver/gen-usbhid-subdriver.sh (refer to docs for details) to walk the UPS and see if it reports any mappings not present in the big table in drivers/belkin-hid.c :\

Thanks for the report, the segmentation fault is not good, and I found where it was, posting a fix. If you are not comfortable with git, in drivers/usbhid-ups.c file there is an instcmd() method. It logs "using Path" just before checking if (hidups_item == NULL) to try other commands - and it is this logging that can crash; removing the line should help for this bit of the issue.

Hi Jim,

Thanks so much for taking the time to look at this stuff!

I found, on line 596, the line you are referring to:

    /* Retrieve and check netvar & item_path */
    hidups_item = find_nut_info(cmdname);
    upsdebugx(3, "%s: using Path '%s'", __func__, hidups_item->hidpath);

    /* Check for fallback if not found */
    if (hidups_item == NULL) {

And I have commented it out to look like this:

    /* Retrieve and check netvar & item_path */
    hidups_item = find_nut_info(cmdname);
    // upsdebugx(3, "%s: using Path '%s'", __func__, hidups_item->hidpath);

    /* Check for fallback if not found */
    if (hidups_item == NULL) {

Recompiling and running provides the following output:

Good news is that the segfault seems to have dissapeared!

But I still can't shutdown the UPS. :( I also see the following line in /var/log/messages after every shutdown attempt:

Apr  7 11:40:56 vps09 kernel: [ 6611.477061] usb 1-1: usbfs: process 1228 (usbhid-ups) did not claim interface 0 before use

Looking at the output from usbhid-ups though seems to suggest (as you mentioned already) that the instcmd shutdown.return is missing (among others).

A couple more command outputs:

# ./upsrw ups1
-- blank --

# ./upscmd -l ups1
Instant commands supported on UPS [ups1]:
-- blank --

I'll try to dig into the gen-usbhid-subdriver.sh and see if I can figure out how to perfrom some of these forensics you mentioned.

I have a number of Liebert GXT3 UPSs that I'll try testing out at some point as well :S

Thanks again! I'll report back with further results as I figure things out.

[EmnaX]

In all the stuff above, the NUT was built with libusb-0.1 but I thought I would try building with libusb-1.0 just for fun. I didn't expect it to fix the issue of the missing shutdown command but I thought I would check it out.

I get an error about Entity not found. I figured I would post it here but I'm just going to go back to compiling with libusb-0.1 so I can focus on the original issue.

[jimklimov]

OTOH the @.***` in logged device report may mean the interface number. When you tried these driver builds, did usbfs complain about not-claim of interface 0?

The rest of issues seem systemic, like something else grabbed the device (and/or set access rights to device filesystem node) so won't let the NUT driver running as your user account have it.

As a workaround (for testing at least), you can try starting the driver as root with -u root CLI option to avoid dropping privileges, to rule out permissions-related issues.

Hi Jim!

I gave libusb-1.0 another shot to explore your questions. I was monitoring /var/log/messages for any entries and usbfs didn't post anything... nothing created any new entries.

hmm, I think my issue compiling with libusb-0.1 vs libusb-1.0 was related to how I was passing the device through to my Debian VM. For all the work so far, I had added the Liebert USB device to the VM through the WebUI. Just now, I though I would try passing through the entire USB controller as a PCI device. So I removed the Liebert USB device and instead added a PCI device AMD Starship USB 3.0 Host Controller at 0000:42:00.3 (which is the USB controller the Liebert UPS is plugged into). Now when I run those same commands, I get some more promising results:

# sudo /usr/local/ups/sbin/upsdrvctl -u root shutdown

Network UPS Tools - UPS driver controller 2.8.0-rc1

I also dug into scripts/subdriver/gen-usbhid-subdriver.sh a bit but that stuff is all way above my head. I'll dump the outputs here in the hope that it may help someone else in the future.

If anyone would like to see the outputs of some commands, let me know... happy to run 'em!

Thanks for the report, the segmentation fault is not good, and I found where it was, posting a fix. If you are not comfortable with git, in drivers/usbhid-ups.c file there is an instcmd() method. It logs "using Path" just before checking if (hidups_item == NULL) to try other commands - and it is this logging that can crash; removing the line should help for this bit of the issue.

Not sure what that means but maybe this is causing the issue?

It logs "using Path" just before checking if (hidups_item == NULL) to try other commands - and it is this logging that can crash; removing the line should help for this bit of the issue.

Thanks @jungeonkim, These comments look like copies of your original comment from Apr 7.

As someone who recently acquired a gxt4 the info in this thread has been incredibly useful so thank you! Is this issue currently solved in git master or would it be a waste of time to attempt to compile from source and build my own deb packages at this time?

At least the segfault fix should be on master in git, yes. Remembering cursorily, the rest of discussion is about config tunables, right?

I haven't played around with this since I made those posts but the UPS currently doesn't shutdown on power loss. Proxmox does properly shutdown but the UPS stays on and slowly drains the batteries completely. It has made it a pain in the butt to restart the server once the power is returned after a power loss. I have a Raspberry Pi running on a different UPS that I'm using to coordinate the start up of a few servers (on power restore) via IPMI commands and WOL magic packets. Not ideal but it works 😃

Seems this is a sort of use-case that can benefit from changes in #2085. Actually the recent PR brushed up functionality that should have been present in earlier releases as well, with a nutshutdown script for integration with systemd-shutdown (might be usable with other frameworks too) which asks the UPS to go down and sleeps to reboot if still alive.

Thanks for the heads up. I'll give the new version a shot when I have some time to play around with it.

I hope that script is pretty stand-alone, in terms that you can adjust your existing copy of /usr/lib/systemd/system-shutdown/nutshutdown to contents of https://github.com/networkupstools/nut/blob/master/scripts/systemd/nutshutdown.in (fixing the paths which a proper NUT build would substitute).

First of all, check if an earlier copy does exist in your system and considers e.g. POWEROFF_WAIT option from /etc/nut/nut.conf -- maybe just adding that line in the config would suffice for the existing deployment. I think it was not thoroughly documented before the recent PR, but support in that script was present for a long time. Well, since 2017 which is between NUT releases 2.7.4 and 2.8.0. Not sure if it was in Debian-patched 2.7.4-x packages - but it was their maintainer that added the original wait logic to this script.
