Is the external machine's network routable to all the OSDs, MDSes, and monitors of your cluster? What do you mean "listed in ceph public networks"? You can't bind machines to multiple public networks; you can specify a cluster network (which the OSDs use for replication) and a public network which is used for client access and everything else. -Greg _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
