This means you have to specifiy --rgw-zonegroup=default and --rgw-zone=default I am guessing our documentation needs updating :( I think we can improve our behavior and make those command works without a realm , i.e return the default zonegroup and zone. I will open a tracker issue for that. >> # radosgw-admin realm list >> { >> "default_info": "", >> "realms": [] >> } > >> # radosgw-admin zonegroup list >> { >> "default_info": "", >> "zonegroups": [ >> "default" >> ] >> } > >> # radosgw-admin zone list >> { >> "default_info": "", >> "zones": [ >> "default" >> ] >> } > > Is that the default behaviour not to create default realm on a fresh radosgw ?
