We upgraded one of our servers from 6 to 7 and after reboot networking is completely broken. When we try to reenable to vmbr0 the system says it does not exists. It is configured in the interfaces file but we still cannot get it up.
 
I'm specifically getting the error cannot find device vmbr0 when I run ifup vmbr0.

It is configured in the interfaces file.
 
What is the output of:
  • ip l
  • ip a
  • cat /etc/network/interfaces
Edit: Waah, too slow...again! :eek: :D

So I was able to get an interface up so that i could get into the UI and that has fixed the bridge simply being missing but i still cant get the bridge to come up on the correct interface and be accessible.

the interface that is supposed to be used byu the bridge is enp25s0f1 and vmbr0.20220806_090602.jpg
 
when I bring up the vmbr0 it docent get a network connection. vmbr1 was just created in the ui and was what fixed the vmbr0 missing even though it was always in the network config. i can remove it and reboot.

So can you explain why this magically works now lol. Its very frustrating.

Also one more question. I now have zfs pools that are not auto importing on boot. I know how to import them through the cli but just wondering why its being stupid.
 
OK zfs was corrected forgot i imported the pool on another system and zfs has a hissy fit when you try to import it in another system.
