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

Any ideas what can be the issue ?
Thanks.
 
Ok, the solution was to

Hardcode MAC Address​


Code:
nano /etc/network/interfaces

Add hwaddress MAC in vmbr0 section

reboot everything
