Hello,

I want to setup a new Proxmox cluster with direct connection.

The servers have 2 1Gbit nics and 2 10Gbit nics.

I want the servers to cumminicate with the 10Gbit link, wich is eth2.

When I try to create a cluster, using the direct IP's that I configured on eth2 at both machines, I get the error: host '10.10.10.11' is not cluster master.

When I use the IP of eth0/vmbr0 it works, but I want to use a faster link for internal communication.

How can I solve this?
 
cluster communication works either with eth0 or vmbr0. so try adding eth2 to vmbr0 (instead of eth0).
 
Hello Tom,

eth0 and eth1 are for normal usage.

vmbr0 can be created on eth2, but I don't have a gateway anymore since the servers are connected directly to each other.

Should I manipulate the eth device numbers in udev/rules.d?
