Two separated full meshs for cluster / corosync in a 3-node-cluster

[mhert]

By the way:

Can someone tell me which traffic goes through which connection on a cluster?

Throught which network goes traffic (oobe) of (builtin) backup / corosync / cluster (same as corosync?) / migration?

Is there an useful network diagramm of proxmox cluster with ceph?

Anyone?

Just read the relevent section of the manual. its not complicated.

Hi together,
I'm planning the same network configuration, 1 mesh network (10G) for CEPH and 1 mesh network (1G) for corosync. I planned using the RSTP mesh for CEPH and corosync. As you guys (@admartinator @mhert) try using only frr, are there any disadvanteges in using RSTP ?

Hi, I have same problem, did you find some solution how to run two mesh networks using openfabric? Or did you use second as RSTP mesh?

Using frr you cant configure two meshes. We're using frr for the ceph mesh and OVS for the corosync mesh.

As EllerholdAG said, I didn't get it to work using frr for both meshes. You can configure it, but then nothing works anymore...

i used a simple network configuration for corosync then.
