Hello, How to configure placement_targets? Which step is wrong in my following steps? I want to use different pools to hold user's buckets. Two pools are created, one is '.bj-dz.rgw.buckets', the other is '.bj-dz.rgw.buckets.hot'. 1. Two placement targets are added to region map. Targets tags are 'hdd' and 'ssd'. ----------------begin---------------------------------- "placement_targets": [ { "name": "default-placement", "tags": [ "hdd" ] }, { "name": "fast-placement", "tags": [ "ssd" ] } ], "default_placement": "default-placement" } -----------end------------------------------------ 2. Map the placement targets to the ceph backend pools. --------- begin -------------------------- "placement_pools": [ { "key": "default-placement", "val": { "index_pool": ".bj-dz.rgw.buckets.index", "data_pool": ".bj-dz.rgw.buckets", "data_extra_pool": "" } }, { "key": "fast-placement", "val": { "index_pool": ".bj-dz.rgw.buckets.index", "data_pool": ".bj-dz.rgw.buckets.hot", "data_extra_pool": "" } } ] ----------- end -------------------------- 3. In order to enable the user create buckets in these two placement_target/ceph pools, I add two placement_tags for my user. ---------------------- begin ---------------------------- "keys": [ { "user": "testuser", "access_key": "6R2MJWR863EREUDD0KTZ", "secret_key": "74eHNNQa1oLBlvZfO2CC2hIU8cobSYxTgeRDtXtH" } ], "swift_keys": [], "caps": [], "op_mask": "read, write, delete", "default_placement": "default-placement", "placement_tags": [ "ssd", "hdd" ], ---------------------end-------------------------------------- 4. Test if it works. - Test if we can create a bucket 'y-ssd' in 'fast-placement target'/'pool .bj-dz.rgw.buckets.hot'. ----------------------- begin --------------------------------- bucket = conn.create_bucket('y-ssd', location='fast-placement') ----------------------- end ------------------------------------- - Test if we can create a bucket 'y-normal' in 'default-placement'/'pool .bj-dz.rgw.buckets'. ----------------------- begin ------------------------------------ bucket = conn.create_bucket('y-normal', location='default-placement') ------------------------ end ---------------------------------------- Result is: ALL these two buckets are created in pool '.bj-dz.rgw.buckets'. 5. In order to test if my 'fast-placement' target works, I change the user's 'default_placement' to 'fast-placement'. And repeat the test in step 4. Reusult is: All those two buckets are created in pool '.bj-dz.rgw.buckets.hot'. 6. conclusion The user's default placement setting works fine. But the placement tags seems not work. Why??? I don't know if this is the right way to use different placement targets. thx joseph ///////Complete Region map/zone map/ user info//////////////////////////////////////// ///// Region map ////////////// # radosgw-admin regionmap get --name client.radosgw.bj-dz-1 --cluster gang2 { "regions": [ { "key": "bj", "val": { "name": "bj", "api_name": "bj", "is_master": "true", "endpoints": [ "http:\/\/s3.mydomain.com:80\/" ], "hostnames": [], "master_zone": "bj-dz", "zones": [ { "name": "bj-dz", "endpoints": [ "http:\/\/s3.mydomain.com:80\/" ], "log_meta": "true", "log_data": "true", "bucket_index_max_shards": 0 }, { "name": "bj-xz", "endpoints": [ "http:\/\/yhg-new:80\/" ], "log_meta": "true", "log_data": "true", "bucket_index_max_shards": 0 } ], "placement_targets": [ { "name": "default-placement", "tags": [ "hdd" ] }, { "name": "fast-placement", "tags": [ "ssd" ] } ], "default_placement": "default-placement" } } ], "master_region": "bj", "bucket_quota": { "enabled": false, "max_size_kb": -1, "max_objects": -1 }, "user_quota": { "enabled": false, "max_size_kb": -1, "max_objects": -1 } } ///// zone map /////////////// [root@yhg-1]# radosgw-admin zone get --cluster gang2 -c /etc/ceph/gang2.conf --name client.radosgw.bj-dz-1 { "domain_root": ".bj-dz.domain.rgw", "control_pool": ".bj-dz.rgw.control", "gc_pool": ".bj-dz.rgw.gc", "log_pool": ".bj-dz.log", "intent_log_pool": ".bj-dz.intent-log", "usage_log_pool": ".bj-dz.usage", "user_keys_pool": ".bj-dz.users", "user_email_pool": ".bj-dz.users.email", "user_swift_pool": ".bj-dz.users.swift", "user_uid_pool": ".bj-dz.users.uid", "system_key": { "access_key": "CZB6EQFR7X36BUW1FYOM", "secret_key": "Gr934Fpaue3FaS2SQn5qE8DCjcntUqisMafUxVbw" }, "placement_pools": [ { "key": "default-placement", "val": { "index_pool": ".bj-dz.rgw.buckets.index", "data_pool": ".bj-dz.rgw.buckets", "data_extra_pool": "" } }, { "key": "fast-placement", "val": { "index_pool": ".bj-dz.rgw.buckets.index", "data_pool": ".bj-dz.rgw.buckets.hot", "data_extra_pool": "" } } ] } //////// user info /////////// { "key": "user:testuser", "ver": { "tag": "_nDultgTsPPMGNB3B2Sk2fc8", "ver": 1 }, "mtime": 1451306407, "data": { "user_id": "testuser", "display_name": "First User", "email": "", "suspended": 0, "max_buckets": 1000, "auid": 0, "subusers": [], "keys": [ { "user": "testuser", "access_key": "6R2MJWR863EREUDD0KTZ", "secret_key": "74eHNNQa1oLBlvZfO2CC2hIU8cobSYxTgeRDtXtH" } ], "swift_keys": [], "caps": [], "op_mask": "read, write, delete", "default_placement": "fast-placement", "placement_tags": [ "ssd", "hdd" ], "bucket_quota": { "enabled": false, "max_size_kb": -1, "max_objects": -1 }, "user_quota": { "enabled": false, "max_size_kb": -1, "max_objects": -1 }, "temp_url_keys": [] } } |
