There's no built-in fallback rule or anything like that. If the rule fails to map for new PGs, they will just not be created. If you have existing PGs and something changes so they don't map, then they will generally continue to run on the OSDs they were previously stored on. No data is ever removed until it's already fully replicated, so breaking your rules can cause various liveness issues with your cluster but it will never compromise data durability. -Greg _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
