You can do that but it is not recommended , I think doc says it would be very good if you have two clusters with different radosgw servers.Hi cephers, Recently I am investigating the geo-replication of rgw, from the example at [1], it looks like if we want to do data geo replication between us east and us west, we will need to build *one* (super) RADOS cluster which cross us east and west, and only deploy two different radosgw instances. Is my understanding correct here? https://ceph.com/docs/master/radosgw/federated-config/#background 1. You may deploy a single Ceph Storage Cluster with a federated architecture if you have low latency network connections (this isn’t recommended). 2. You may also deploy one Ceph Storage Cluster per region with a separate set of pools for each zone (typical). 3. You may also deploy a separate Ceph Storage Cluster for each zone if your requirements and resources warrant this level of redundancy. Regards, Vikhyat If that is the case, is there any reason preventing us to deploy two completed isolated clusters (not only rgw, but only mon and osd) and replicate data between them?
