I'm not entirely sure what you mean, but let me clarify what I meant a bit. Existing monitors take their monmap from their own stores. All monitors in a quorum will see the same monmap. Existing monitors do not care about the configuration file for their monmap. 'mon_host' and 'mon_initial_members' are only used by clients trying to reach the monitors AND when creating a new monitor. Therefore, when creating a new monitor, 'mon_host' must contain the ips of the existing monitors PLUS the monitor you are creating, and 'mon_initial_members' must contain the hosts of the existing monitors PLUS the host of the monitor you are creating. Your initial email reflected a lot of other ips on the 'extra_probe_peers' (which is basically the contents of mon_host during the probing phase, while the monitor tries to find the other monitors), which is consistent with mon_host being wrongly populated. -Joao _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
