[ceph-users] RGW don't use .rgw.root multisite configuration

Hello, for my multisite configuration, i create and use an root pool other than .rgw.root to store realm and zone configuration with the follow option: rgw_realm_root_pool=myzone.rgw.root rgw_zonegroup_root_pool=myzone.rgw.root rgw_zone_root_pool=myzone.rgw.root But , i can see during the syncronize with my secondary zone (real only) , radosgw need to read and write period in .rgw.root. Is there an option or other to avoid read and write on the root pool .rgw.root ? Is it mandatory ? Pacific regards Guillaume
