Changing IP address

[michaelf]

Hello!

Weird case: after changing ip address (as per https://www.servethehome.com/how-to-change-primary-proxmox-ve-ip-address/ ) and restarting Proxmox now boots as follows:
1) the blue windows appears with 4 boot options (Proxmox VE GNU/Linux, Advanced options,...)
2) after booting Proxmox (the first default option or Advanced options) the server restarts for the second time and there's just a black screen...

Q1: May the ip address change even theoreticaly lead to such problem?

Q2: What would you recommend in this situation?

Regards,
Michael

Hi,

Q1: May the ip address change even theoreticaly lead to such problem?

No. The IP address gets set way after the boot process, where your box seems to get stuck.
Did you change anything other before rebooting? Configurations, package updates (how did you exactly perform them?) etc. etc.

Q2: What would you recommend in this situation?

First, try to go to Advanced Options and select either an entry marked (recovery mode) or an older kernel. I.e. the first entry normally is the same as the default boot entry, thus select one with a different kernel version.

2) after booting Proxmox (the first default option or Advanced options) the server restarts for the second time and there's just a black screen...

When exactly does it reboot? Right after booting the default boot entry? Or somewhere later on?

On what Proxmox VE version are you (approximately)? At least the major version would be good to know, as well as the kernel version(s) stated in GRUB.

"No. The IP address gets set way after the boot process, where your box seems to get stuck." - agree, it may be just a coincidence.

"Did you change anything other before rebooting? Configurations, package updates (how did you exactly perform them?) etc. etc." - no, just changed ip and restarted the server.

"When exactly does it reboot? Right after booting the default boot entry? Or somewhere later on?" - after booting the default boot entry the screen displays
[ 0.098474] x86/cpu:SGX disabled by BIOS
...
/dev/mapper/pve-root: clean, 86309/6291456 files, ....nnnn blocks
/

and hangs with this picture for ~ 1 min, then restarts and seem to turn of the monitor at all ("~No signals detected" on the monitor, but the server is working).

"On what Proxmox VE version are you (approximately)? " - 8.0.4, kernel version ... ???

("~No signals detected" on the monitor, but the server is working).

Just to clarify - so although you have no graphical output on the monitor, the server itself is working? I.e. you can ping it, access it via ssh/web interface?

What kind of hardware do you have? Esp. graphics chip in this case.
I'd recommend updating to the latest 8.1 release in any case, that might help - there have been lots of fixes (and security updates!) since 8.0.4.

"Just to clarify - so although you have no graphical output on the monitor, the server itself is working? I.e. you can ping it, access it via ssh/web interface?" - no, I can't do anything (ping, ssh...) - I meant the coolers are rotating and all LEDs look like everything is OK...

Booting into recovery mode hangs on this:

"Starting ifupdown2-pre.service - Helper to synchronizeboot up ..."

P.S. seems it is the hdd to blame...
