[SOLVED] Access fabric full mesh network with local VM

[christopher.heinrich]

Hello,

We operate multiple 3-node clusters. For the VM LAN, each node has 2× 10 GbE ports in a bond. Additionally, each node is equipped with 4× 25 GbE ports, which we’ve used to create a high-speed interconnect between the nodes for fast local migration and replication. On one of the hosts, there is a VM running Proxmox Backup Server. Is it possible to connect a secondary NIC on the PBS to the mesh network?

Best regards,
Christopher

We have now solved the issue as follows: In the SDN, a VXLAN was created with the fabric as the underlay network. In addition, a VNet was created that includes the VXLAN as a zone. Now, on each node, an IP address must be added to the VNet interface under /etc/network/interfaces.d/sdn. The PBS is assigned a second interface, bridged to the VNet, with an IP address from the same subnet.

The PBS storage needs to be reconfigured using the new IP from the VNet.

Best regards,
Christopher
