So it's mapped into a zone (at least on my Giant version 0.87)
and in my simple non-federated config it's in the default region+zone:
[root@rgw ~]# radosgw-admin region list
{ "default_info": { "default_region": "default"},
"regions": [
"default"]}
[root@rgw ~]# radosgw-admin zone list
{ "zones": [
"default"]}
[root@rgw ~]# radosgw-admin region get
{ "name": "default",
"api_name": "",
"is_master": "true",
"endpoints": [],
"master_zone": "",
"zones": [
{ "name": "default",
"endpoints": [],
"log_meta": "false",
"log_data": "false"}],
"placement_targets": [
{ "name": "default-placement",
"tags": []}],
"default_placement": "default-placement"}
[root@rgw ~]# radosgw-admin zone get
{ "domain_root": ".rgw",
"control_pool": ".rgw.control",
"gc_pool": ".rgw.gc",
"log_pool": ".log",
"intent_log_pool": ".intent-log",
"usage_log_pool": ".usage",
"user_keys_pool": ".users",
"user_email_pool": ".users.email",
"user_swift_pool": ".users.swift",
"user_uid_pool": ".users.uid",
"system_key": { "access_key": "",
"secret_key": ""},
"placement_pools": [
{ "key": "default-placement",
"val": { "index_pool": ".rgw.buckets.index",
"data_pool": ".rgw.buckets",
"data_extra_pool": ".rgw.buckets.extra"}}]}
and my user if associated with the default region+zone, thus it's data goes into .rgw.buckets + .rgw.buckets.index [+ .rgw.buckets.extra]
Buckets seems a naming container at the radosgw level, above the underlying Ceph pool abstraction level, 'just' providing object persistence for radosgw abstraction/object FS on top of Ceph Pools... I think.
So more users associated with same region+zone can share buckets+objects?
Would be nice with a drawing showing abstractions at the different levels possible woth links to details on administration at different levels :)
Lot of stuff to grasp for a newbie just in the need of a S3 service for an App usage :)
