Linux server hangs on shutdown (lemmy.fish)

I've had two server oses here: alma linux and debian(currently). On both of them, they will hang when I shut them down from cockpit, and they hang at the end of the shutdown.

Also, it takes an hour to a day to have this issue start. if it's restarted two times in a row quickly, it works perfectly fine for some reason.

What I've tried:

  • setting "acpi=off" and "acpi=force" kernel parameters in grub
  • removing my nvidia gpu(i was using nouveau drivers)
  • changing distros

nothing worked. here are some things that both distros had in common with eachother:

  • systemd
  • cockpit
  • libvirt & qemu
  • docker

does anyone have advice? nothing i've seen online has worked. thank you for suggestions

Your machine isn't shutting down, it's trying to sleep.

You also have active KVM instances which are fighting to keep it alive.

can you elaborate on why you suspect this? The cockpit reboot or shutdown button uses the shutdown command directly along with a --reboot or --poweroff flag.

    onSubmit(event) {
        const Dialogs = this.context;
        const arg = this.props.shutdown ? "--poweroff" : "--reboot";
        if (!this.props.shutdown)
            cockpit.hint("restart");

        cockpit.spawn(["shutdown", arg, this.state.when, this.state.message], { superuser: "require", err: "message" })
                .then(this.props.onClose || Dialogs.close)
                .catch(e => this.setState({ error: e.toString() }));

        event.preventDefault();
        return false;
    }

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
