[SOLVED] VPS - New install - GRUB Problem - Network down

[Michael-stk]

Hi everybody,

I need your help

I am new to Proxmox and wanted to install it on my cloud vps.

I followed the steps below to install it on debian 11.
(https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye)

Almost all of the installation goes fine, until I get to grub
I get an error message and no matter what I do nothing works.

Error:
Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.

I already tried modifying /etc/default/grub with
GRUB_DISABLE_OS_PROBER=false
and after that - update-grub - Same error

I have already restarted the server, I can no longer log in via putty and the website interface is no longer accessible. but can still log in via vnc console.

hopefully somebody can help me.

Could it be that grub is not allowed on my vps?
Can I check this?

Are there any other options instead of grub? or should I switch to a completely different system instead of proxmox.

Please your help!

Thank you very much in advance

Sincerely,
Michael

this warning is benign - it just says that grub will not scan for *other operating systems*, which is what you want on a PVE system (since it would potentially scan the guest volumes and can actually break them!).

you should probably check the boot log via VNC to see what's going wrong.. (journalctl -b)

Hi Fabian, thanks for your quick response

There is a lot in the log (journalctl -b) I have copied the errors that stand out and were colored red

Dec 21 09:26:07 vps systemd[1]: Failed to start chrony, an NTP client/server.
Dec 21 09:29:03 vps lvm2-activation-generator: lvmconfig failed
Dec 21 09:30:00 vps pve-ha-lrm[12131]: unable to write lrm status file - unable to open file '/etc/pve/nodes/vps/lrm_status.tmp.12131' - No such file
Dec 21 09:30:03 vps pvecm[12662]: got inotify poll request in wrong process - disabling inotify

After command
apt install proxmox-ve postfix open-iscsi

I restarted the server and then putty stopped working.
I can still log in via vnc console but only typing and no more copying texts.

As soon as I log into the vnc console then I get the error

[16.779223] l1TF CPU bug present and SMT on, data leak possible. See CVE-2018-3646 and https:www.kernel.org/doc/html/latest/admin-guide/hw-vuln/l1tf.html for details

Hope this gives you enough information, otherwise please let me know what commands I should run to give you a better answer.

Thank you!
Kind regards.
Michael

[fabian]

is network coming up? (systemctl status networking ; ip -c a)

what about the PVE services? (journalctl -b -u pve-cluster -u pveproxy -u pvedaemon?

 

[Michael-stk]

Cant copy past, so screenshot

 

[fabian]

well, your network config is broken it seems.. I'd start with fixing that then you should also be able to copy the full boot log via SSH..

 

[Michael-stk]

Network fixed, thanks. So easy

 

[fabian]

so everything works now? note that you have cloud-init installed it seems, this is normally not supposed to be done on a hypervisor host..

 

[Michael-stk]

Yes it seems to work now, I'm logged in now.

I installed Debian 11 from my hosting company. Will this be a problem? Can I remove it better?

 

[fabian]

it's probably better to remove it, else it might pick up cloud-init configs you/PVE generates for the guests and apply them to the host..

 

[Michael-stk]

I can't figure out how to delete it, most of them talk about creating a file

/etc/cloud/cloud-init.disabled

Or using his?

Its for ubuntu

 

[fabian]

uninstalling the package should be enough I think.. or contact your provider's support if not sure.

 

[Michael-stk]

OK, I'm going to look at that.

Thank you very much for your help and your quick response.

Kind regards,
Michael
