[SOLVED] Cluster with Multiple NICs on Dacentec Network

[Coolguy3289]

Hello,

New to the forums here, but I am in need of a bit of assistance in understanding how to get a cluster to work with multiple nics. So here is the situation:
I have 2 hosted servers through Dacentec.
Both of them have 2 NICs, On each eth0 and vmbr0 hold one of the public IPs that allow me to access it from the internet over SSH, as well as access the Proxmox Web GUI.
eth1 on both servers has been hooked up into a switch and are connected to each other in the data center over a VLAN. I have created vmbr1 and set the IP address to 10.0.0.2 and 10.0.0.3 respectively in each server. I have also added the IP to the server's host file, and rebooted the server.
The Problem:
I can still access the machines from the internet, however I can not ping the other machine at all, nor add the slave node to the master cluster I created. the new internal network IS showing active in the network list on the web GUI on both machines. Is there anything I am missing? or could it be a configuration error in the data center?
Attached are screenshots of my network configuration on both boxes.

If you did all configuration well and still can't ping then it's an most probably a network problem.

To your configuration:
I would not create a bridge for the interconnect network, just a plain network device. Can you please check if they actually have a link? The tool ethtool will inform you about that (you need to install this) and then run

ethtool eth1

on each node.

The issue has been fixed. What I did was correct. The problem had been at the datacenter.
