I'm setting up federated gateway following https://ceph.com/docs/master/radosgw/federated-config/, it seems one cluster can have multiple instances serving multiple zone each(be it master or slave), but it's not clear whether I can have multiple radosgw/httpd instances in the same cluster to serve request for same master zone, can anybody help answering this: 1. Should I setup multiple instances like us-east-1, us-east2.. for each physical host ? Should I be creating a separate keyring for each phyiscal host? Or just create single keyring and on every physical host refer it to us-east-1? 2. Can I use load-balance in front of these radosgw instances? If yes, should the "host=" entry set the the load balancer name or local host name? 3. While librados is atomic but REST API does not have write lock, so in the case when multiple user try to perform the write to same object through different radosgw instances for same master zone, what will happen? Will the write request to object being written be denied or potentially data corruption can occur? Thanks, Fred -------------- next part -------------- An HTML attachment was scrubbed...
