Hallo,
i have a cluster with two nodes , they have a public ip address each, and a dedicated NIC for internal communication (no switch a crossover cable with two 10Gbit NICS), i've already used it for creating the cluster and it works, if i move VMS between the nodes, the cluster uses only internal network.
These servers are on hetzner, so i must use routed configuration. I need to create a cluster of VMS in which most of them will communicate only between them, and only a few web servers and a load balancer will need other public addresses. My goal would be to make VMS communicate between themselves, using a single network, in order to move them in a transparent way between nodes, and also using the "cluster internal" network/NICS, to avoid using public bandwidth in order to leave it for external access. I already succeed in creating private network in each node, and VMS inside a single node communicate between them and also I masquerade them with iptables on the host to make them reach internet. But I don't figure how to use SAME LAN in both nodes. I should use VLAN, but i still don't understand how!
Thanks in advance
