[SOLVED] Can't SSH on nodes and GUI are not loading , after upgrade 6.4 -> 7.1 .

[arhimede]

I just upgrades 3 nodes in a cluster, all from 6.4 to 7.1

after reboot, i cannot SSH on any node, and the GUI are not loading.

Still, all LXC containers are un and running.

I suspect an issue with the node network interface

what should i do ?
i can ask for KVM , Hetzner servers

Thanks.

I think i missed the step related to MAC
https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0#Linux_Bridge_MAC-Address_Change
And being Hetnzer, they are very strict in terms of MAC's.

Using Hetzner's Rescue system , i checked the /etc/network/interfaces , nothing there.
Still all LXC are up and running, but i can't SSH to server , and GUI is not loading.

I did the below, still no luck

ln -s /dev/null /etc/systemd/system/pve-firewall.service

Any ideas what can be the issue ?
Thanks.

I can SSH into the node from one of LXC container
But i have no idea what to do

I read this thread : https://forum.proxmox.com/threads/w...or-web-gui-but-vms-are-running-perfect.55515/
and i noticed that in my /etc/network/interfaces a *maybe* typo , "bridge-ports" instewd of "bridge_ports", did not solved the problem.

pve-firewall is disabled

Ok, the solution was to

Hardcode MAC Address​

nano /etc/network/interfaces

Add hwaddress MAC in vmbr0 section

reboot everything
