I found the following info in the documentation: "You need to know which IP address to use for the cluster’s first monitor daemon. This is normally just the IP for the first host. If there are multiple networks and interfaces, be sure to choose one that will be accessible by any host accessing the Ceph cluster." So that would be the public network in your case. See [1]. Just curious: why do you want to use separate networks? You might as well use bonded interfaces on the public network (i.e. LACP) and have more redundancy there. I figure that you might even make more effective use of the bandwidth as well. Gr.
