SDN VLAN broke main network [solved]

[jrobert]

In setting up a VNet for my SDN settings, I accidentally set the VLAN tag to 1 instead of 10. I then lost my network connection on node 1 (I was able to delete the vnet using node 2 before either 2 or 3 had issues). I've been able to reboot node 1 and get to the command line, but I still have no network, and I can't seem to edit /etc/pve/sdn/vnets.cfg to remove the offending vnet. I get a Permission denied message if I try to change permissions, change ownership, or edit the file.

Any ideas has to how to get this node back without reinstalling?

Because your server 1 is not in quorum with the rest of the cluster, /etc/pve is in read-only mode.
We could override that and fix it that way, but probably easier would be to nano-edit the /etc/network/interfaces.d/sdn file that the "active" config is saved to (to fix the typo) and the either reboot or ifreload -a to get the cluster up and running again, get the quorum back, then re-apply the new/changed settings (for example by changing a comment in the SDN)

Thanks, I'm back up and running now. Good to know where the active config is. Love proxmox and Linux, but it's sometimes a bit daunting to figure out where things are when your starting out.
Thanks again for the help.

No problem. Also maybe edit the first post to have the [solved] flair to it.
