Indeed. To be clear, Alexander, do you have those two 10GE ports bonded? If so, then I agree with Herr Sander that there is no benefit to defining the cluster_network, and indeed you may be confusing code by doing so. The cluster network should only be defined if it's *different* from the public network. The public network is how clients communicate with the Ceph cluster. If there's a cluster_network, it is only used for internal replication and heartbeating within Ceph. > It is optional and only recommended if you have a network that is at least > twice as fast as the public network. Well, say someone has two dual-port 10GE NICs in each system. They could either bond all four together (which I *think* works but haven't tried) for a public network, or bond one port on each NIC together for the public, and one on each for the private network. I do usually recommend that people not bother with a cluster network if they're using 25GE or better, especially with very dense nodes. > >> After this I only see this as paramter in the GUI screen, under host / ceph >> / configuration in the section Configuration Database >> Und [global] I still see a second entry named public_network = 192.168.x.x >> (this is my management network of the proxmox host). > > Change in the config db do not get written to the ceph.conf file.

If it's in ceph.conf, then absolutely.
