The cluster network handles object replica traffic and recovery traffic between OSDs, and heartbeat traffic between OSD. OSDs communicate with monitors via the public network. Monitors and metadata servers operate exclusively on the public network. The only case where they'd need to be able to route to each other is if you have some OSDs with only one NIC that can only operate on the public network. I believe there is a note about it in the documentation. Generally, it's a good idea to keep them separate if you can since monitors and metadata servers don't use the cluster network. > _______________________________________________ > ceph-users mailing list > [email protected] > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com -- John Wilkins Senior Technical Writer Intank [email protected] (415) 425-9599 _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
