Changing cluster network interface

[dthompson]

Hi all,

I couldn't find this so apoligies if its been asked before and if so and someone could point me to a wiki article or a forum post, I would appreciate it.

I have 4 Proxmox servers in a cluster. The setup as as follows:

vmbr0 --> eth1 (1GB)
vmbr1 --> eth2 (1GB)
vmbr2 --> eth3 (10GB)
vmbr3 --> eth4 (10GB)

I have a cluster VLAN setup on the vmbr0 interface over 1GB.
I'd like to know how hard (easy) it is to switch all the servers from using the 1GB interface to only using the 10GB

Ideally, I'd like to remove the 1GB networks completely and run solely on 10GB. Is it possible to easily change this around, or is this best to rebuild the cluster from scratch and only use the 10GB network interfaces?

Thanks for any help.

Can you show your network configuration?
If you can configure the same IP addresses on another interface / VLAN you should be okay. Changing the IP addresses themselves will be tough in a cluster.
