Monitors use the public network, not the cluster network. Only OSDs use the cluster network. The purpose of the cluster network is that OSDs do a lot of heartbeat checks, data replication, recovery, and rebalancing. So the cluster network will see more traffic than the front end public network. See http://ceph.com/docs/master/rados/configuration/mon-osd-interaction/ By contrast, Ceph clients connect to monitors and OSDs, so they must be on the public network. See the diagram here: http://ceph.com/docs/master/rados/configuration/network-config-ref/ Notice that all daemons use the public network? This is because clients connect using the public network. Yet, only OSDs use the cluster network.
In your configuration, you specified the following: [mon.controller1] host = controller1 mon addr = 10.100.10.1:6789 public addr = 10.100.0.150 cluster addr = 10.100.10.1 cluster network = 10.100.10.0/24 public network = 10.100.0.0/21 The IP address for the mon.controller1 is set to a cluster network IP address--namely, 10.100.10.1:6789. Since the monitor only connects on the public network, and you have specifically told it to connect only on a cluster network, that is why the monitor is running on the cluster network. Your monitor address should be something like 10.100.0.155:6789 in that range. However, now that you have a monitor IP address, changing it can be a bit troublesome too. See the following: http://ceph.com/docs/master/rados/operations/add-or-rm-mons/#changing-a-monitor-s-ip-address On Wed, Jan 15, 2014 at 1:13 PM, Jeff Bachtel < jbach...@bericotechnologies.com> wrote: > If I understand correctly then, I should either not specify mon addr or > set it to an external IP? > > Thanks for the clarification, > > Jeff > > > On 01/15/2014 03:58 PM, John Wilkins wrote: > > Jeff, > > First, if you've specified the public and cluster networks in [global], > you don't need to specify it anywhere else.
