Cluster with two dedicated servers

[tstav]

Hi all,

I have two dedicated servers in an ISP datacenter.
They are located in the same datacenter but they belong in different networks.
They are also connected with a backend connection on a separete ethernet interface.
Can a cluster be made with these two computers?

TIA

NO - Cluster nodes should be in the same network.

Thanks Dietmar.

you can join them in a vpn.

you can join them in a vpn.

Future versions of PVE will use corosync (IP multicast) for cluster communication. I am not sure if that work with a vpn.

As I stated in my message, the two servers have a second eth interface. The second interface IPs are in the same network, which actually is a dedicated Vlan.
I tried to setup a master and slave cluster on that interface but the system replied that it can only setup a cluster on the vmbr0 interface, which is tied to the public IPs on both systems.

If that is the problem, simply tie the private net to vmbr0, and use something else for the puplic IPs.
