Proxmox 8 hangs after upgrade from 7

[mhadzi]

Hello all,

I would appreciate any help I can get. I’m new to Proxmox, so step-by-step instructions would be greatly appreciated.

I recently upgraded an older server that worked fine with version 7. It’s a SuperMicro X11SSH-F/-LN4F. However, the server no longer stays active long enough for me to send any commands to fix the issues. It freezes at random times—sometimes during login and other times even before that. The only way to do anything is to power it down and back up again, but even then, I can’t fix anything before it freezes again. So far, I’ve had no luck.

I’ve also noticed that whenever my server is connected to my home network, the entire network crashes, and I can’t access any other computers on the network.

Here’s what I’ve tried so far:

• Running the recommended network repair commands from the wiki, but the server freezes before I can complete them.

• Deleting ntpdate (as suggested in a forum), but this didn’t fix the problem.

• Booting the server with an older kernel—same freezing issue.

• Starting in Rescue mode, but it still freezes without showing any error messages.

• Using a GParted Live CD, but I’m unsure what steps to take from there.

This is all over my head, and I’d like to avoid a fresh install of VE6 or VE7, as those versions worked fine. Any guidance to rescue the environment would be greatly appreciated!

Would try to exchange the os disk to any other or a usb disk and install pve 8 onto. Evaluate if you have any hw error then or it's related to your old os disk system.

Thank you for your response and recommendation.

I installed Proxmox 8 onto a USB drive and tested it on another computer to confirm that the USB works properly, and it does. However, when I tried booting the USB on the server, the results were the same.

I attempted both the regular Proxmox boot option and the rescue mode, but the server still hangs or freezes at random times. Sometimes it freezes before the login page appears, and other times it freezes after loading and logging in.

Can you think of anything else I can try to resolve this issue?

So there's somethink with your hardware and it's not related to your os disk nor the pve os itself.
Run memtest for few hours (it's installed with pve in /boot by default lso).
