Swithing to new 10gb NIC from 1gb NIC on motherboard

Hi!

I’ve got some difficulties with switching to new 10gb NIC at my TrueNas Scale server.

Right now, system works under eno1 interface. In CLI I can’t disable or remove eno1, because it screams about apps connected to this interface, even if I disable all apps, still can’t disable/remove old NIC.

Somehow this NIC is blocked. Do you have any reasonable NIC replacing procedure on TrueNas Scale?

Much apreciated for any help!

Stopping the individual apps doesn’t change the configuration of the system. Is it set to use eno1 for the apps? If so, you’ll need to change that. Apps → Settings → Advanced Settings → Route v4 Interface

Tried that, but app advance setting can’t switch to other route, because it is not yet connected by cable (got only one rj45 cable).

I changed Route Interface for the other NIC after plugging cable, but still couldn’t change anything to eno1 interface (changing IP, remove interface).

I will try to connect both cards at the same time, maybe then I can do some config changes. I’m little by little loosing ideas how to do it painlessly.

I wouldn’t want to install fresh TrueNas from different SSD.

I think that would be essential–there are a lot of things that would break if there were no configured network interface. Install and configure the new one, configure the apps service to use it, then delete configuration for the old one and remove it.

Success! You were right Dan. I did like you sugested, and it worked.

Thank you for help!
