How to shutdown Proxmox 6 from CLI?

[vikas027]

I am using Proxmox Virtual Environment 6.0-4 on HP Z620 workstation server. Sometimes after clicking "Shutdown" the server hangs forever, I have looked at the logs but could not find anything useful. \

What is the correct order to shutdown the systemd services? I want to try shutting down proxmox gracefully and attempt to shutdown the OS using poweroff command.

root@proxmox:~# systemctl list-unit-files --state=enabled | grep ^pve
pve-cluster.service enabled
pve-firewall.service enabled
pve-guests.service enabled
pve-ha-crm.service enabled
pve-ha-lrm.service enabled
pve-manager.service enabled
pvebanner.service enabled
pvedaemon.service enabled
pvenetcommit.service enabled
pveproxy.service enabled
pvestatd.service enabled
pve-daily-update.timer enabled
pvesr.timer enabled
root@proxmox:~#

Poweroff takes already care of the correct order, so just use it and look at the screen for possible errors.

As I said, the system froze and there was no trace of any logs, thus I wanted to test the shutdown process without Proxmox.

From doing systemd-analyse and systemctl list-unit-files I came up with the following script for disabling and and enabling Proxmox services and related daemons. In order to start stuff up again you need to reboot, to make sure you get a clean boot in the right order. Your mileage may vary but I have used it quite ok for when I'm configuring non PVE stuff and I'm rebooting all the time and want PVE out of the way. Use at your own risk, but hope this helps:
