在 default Zonegroup 增加新的 Placement target 名為 slow 並且賦予 tag 為 slow

 1 $ radosgw-admin zonegroup placement add --rgw-zonegroup default --placement-id slow --tags slow
 2 
 3 [
 4     {
 5         "key": "default-placement",
 6         "val": {
 7             "name": "default-placement",
 8             "tags": [],
 9             "storage_classes": [
10                 "STANDARD"
11             ]
12         }
13     },
14     {
15         "key": "slow",
16         "val": {
17             "name": "slow",
18             "tags": [
19                 "slow"
20             ],
21             "storage_classes": [
22                 "STANDARD"
23             ]
24         }
25     }
26 ]

替 default-placement Placement target 新增名為 default-placement tag

 1 $ radosgw-admin zonegroup placement modify --rgw-zonegroup default --placement-id default-placement --tags default-placement
 2 
 3 [
 4     {
 5         "key": "default-placement",
 6         "val": {
 7             "name": "default-placement",
 8             "tags": [
 9                 "default-placement"
10             ],
11             "storage_classes": [
12                 "STANDARD"
13             ]
14         }
15     },
16     {
17         "key": "slow",
18         "val": {
19             "name": "slow",
20             "tags": [
21                 "slow"
22             ],
23             "storage_classes": [
24                 "STANDARD"
25             ]
26         }
27     }
28 ]

 

在 default Zone 增加新的 placement pool，並且命名为 slow。建置過程中需配置 index-pool, data-pool 與 –data-extra-pool

radosgw-admin zone placement add --rgw-zone default --placement-id slow --index-pool slow.rgw.buckets.index --data-pool
