Update Network card existing V4.3

[tomc]

Hi
We are updating the network card in the system to a 10GB NIC
At the moment the server has a dual on board GB NIC.
In the proxmox GUI under Network it is showing
eth0 Network Device Yes No
eth1 Network Device No No
vmbr0 Linux Bridge Yes Yes eth0 192.168.0.6 255.255.255.0 192.168.0.1
I would assume, when I put the new NIC in there will be added.
eth2 Network Device No No
eth3 Network Device No No
To keep the same IP address and mask and gateway, I would assume I would change the eth0 setting to
eth0 Network Device No No
To keep the same IP address and mask and gateway, I would assume I would change the eth2 setting to
eth2 Network Device Yes No
and change the vmbr0 setting to
vmbr0 Linux Bridge Yes Yes eth2 192.168.0.6 255.255.255.0 192.168.0.1
Question.
Is a reboot required?
Do I have to change any other settings?
Will I loose connection to the GUI?
How do I return to original settings if required and I don't have access to the GUI?
Sorry, I am new with Linux as well.
I noticed in /etc/network/interfaces there is the information.
Can I return to previous settings or change to new settings by editing this?
And will this impact on the existing cluster?

During initial setup can a specific NIC be chosen?

Thank you.

Yes

No

Will I loose connection to the GUI?

Temporarily, during the restart.

How do I return to original settings if required and I don't have access to the GUI?

If something goes wrong and you loose network access to your server you need a console. For restoring the old values: save the original content of /etc/network/interfaces somewhere and store it back in case of a problem.

And will this impact on the existing cluster?

No

During initial setup can a specific NIC be chosen?

No

Hi Richard
Thank you very much for your reply.
We have carried out the procedure and it was as you said, all worked OK.
I*n fact easier, all we changed in the GUI was
change the vmbr0 setting to
vmbr0 Linux Bridge Yes Yes eth2 192.168.0.6 255.255.255.0 192.168.0.1.
Reboot
Plug the Ethernet cable into the correct port and away we go.
