[SOLVED] boot runs into Debian GNU - I want to avoid this

[schnellschuss]

Hi,

after changeing my hardware that I used for the pbs (was: Acer easystore h340 with atom CPU, 2GB RAM; now: Fujitsu P900 with i5 CPU, 16GB to come) I ran into issues. The system boots nicely, I have a monitor to see the procedure and the system starts the Debian GNU/ Linux. As a consequence, the system has it´s own behavior of suspending (which seems to make the server unavailabe on the network). With my prior setup on the easystore, this did not occur - I also followd that on the attached monitor.

While I have of course tried to shut off all kind of energy/power management in both, the BIOS and the Debian GNU, the server still runs into a kind of suspend mode, which is not suitable to my scheduling of tasks and booting/ shutting down intentionally by Magic Paket/ cron.

I am now wondering if I may have missed the option where I could choose, whether or not to boot into the Debian GNU? Any help for that as well as supporting material I can read into (did not find the solution in the manual so far) is well appreciated!

Hi,

did you install proxmox from the ISO? Can you check what your log says at the such a suspend happened the last time, just edit the date in this command:

journalctl --since "2022-05-31 16:00:00"

Hi,

thanks for the reply. I have checked out and it seems to come from the network manager - not so familiar still with Linux...please see the relevant part from systemctl:

You can try to disable sleep on the server

systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Thanks a lot shrdlicka, that did the trick!

A bit intrigued by the solution I wanted to understand where the sleep trigger would come from, this post [0] hints to run systemd-inhibit, which is the same as systemd-inhibit --list
And from man systemd-inhibit:

DESCRIPTION
systemd-inhibit may be used to execute a program with a shutdown,
sleep, or idle inhibitor lock taken. The lock will be acquired before
the specified command line is executed and released afterwards.

--list
Lists all active inhibition locks instead of acquiring one.

On a default proxmox install from iso you get:

No inhibitors.

On a debian gnome desktop install you get multiple inhibitors.

From your posted log:

Jun 01 10:21:38 backserv gnome-shell[1519]: Screen lock is locked down, not locking

So I assume that gnome-shell is installed afterwards or proxmox is installed on top of a debian gnome desktop install, both setting the multiple inhibitors, which will trigger sleep state.
