Network interface naming

[eoinkim]

Hi all,

I'd like to get some opinions about network interface naming on Proxmox node. Although I do my best to get the same hardware, there might be some situations that I cannot, which will result in different interface names on different nodes. Since I have to make a multi-node cluster with cluster-wide private networks, I believe this is quite important.

I know that this can be amended from a GRUB configuration so that the interface name can be shown as eth0, eth1 and so on. I am wondering if this is actually the best way to do or are there better ways to do this? Thanks.

It is better to use systemd .link configuration for such things:

Hi Dietmar,

Thanks for that, I'll have a look. By chance, is there a way for doing this during the installation? As a side note, I have set up a zfs over iscsi using FreeNAS (getting help from https://github.com/TheGrandWazoo/freenas-proxmox). It was okay until I changed interface name by grub. SSH key keeps getting compromised and the system cannot find LUN. Apologies for brief explanation but that's why I am asking this question - is it possible to set the name during the installation?

Thanks again.

AFAIK this is not possible at installation time.

Yeah, I thought so. Thanks.
