3.10.7. 将对象从一个存储类转换到另一个存储类

对象生命周期转换规则允许您将对象从一个存储类转换为另一个类。

先决条件

安装 Ceph 对象网关软件.
Ceph 对象网关节点的根级别访问权限.
创建的用户具有访问权限的 S3 用户。

流程

创建新数据池：

语法

ceph osd pool create POOL_NAME

示例

[root@rgw ~]# ceph osd pool create test.hot.data

添加新存储类：

语法

radosgw-admin zonegroup placement add  --rgw-zonegroup default --placement-id PLACEMENT_TARGET --storage-class STORAGE_CLASS

示例

[root@rgw ~]# radosgw-admin zonegroup placement add  --rgw-zonegroup default --placement-id default-placement --storage-class hot.test
{
        "key": "default-placement",
        "val": {
            "name": "default-placement",
            "tags": [],
            "storage_classes": [
                "STANDARD",
                "hot.test"
            ]
        }
    }

为新存储类提供区放置信息：

语法

radosgw-admin zone placement add --rgw-zone default --placement-id PLACEMENT_TARGET --storage-class STORAGE_CLASS --data-pool DATA_POOL

示例

[root@rgw ~]# radosgw-admin zone placement add --rgw-zone default --placement-id default-placement --storage-class hot.test --data-pool test.hot.data
{
           "key": "default-placement",
           "val": {
               "index_pool": "test_zone.rgw.buckets.index",
               "storage_classes": {
                   "STANDARD": {
                       "data_pool": "test.hot.data"
                   },
                   "hot.test": {
                       "data_pool": "test.hot.data",
                  }
               },
               "data_extra_pool": "",
               "index_type": 0
           }

注意

在创建具有写入一次的冷或归档数据存储池时，请考虑设置 compression_type。

在数据池中启用 rgw 应用程序：

语法

ceph osd pool application enable POOL_NAME rgw

示例

[root@rgw ~] ceph osd pool application enable test.hot.data rgw
enabled application 'rgw' on pool 'test.hot.data'

重新启动所有 rgw 守护进程。

创建存储桶：

示例

[root@rgw ~]# aws s3api create-bucket --bucket testbucket10 --create-bucket-configuration LocationConstraint=default:default-placement --endpoint-url http://1x.7x.2xx.1xx:80

添加对象：

示例

[root@rgw ~]# aws --endpoint=http://1x.7x.2xx.1xx:80 s3api put-object --bucket testbucket10  --key compliance-upload --body /root/test2.txt

创建第二个数据池：

语法

ceph osd pool create POOL_NAME

示例

[root@rgw ~]# ceph osd pool create test.cold.data

添加新存储类：

语法

radosgw-admin zonegroup placement add  --rgw-zonegroup default --placement-id PLACEMENT_TARGET --storage-class STORAGE_CLASS

示例

[root@rgw ~]# radosgw-admin zonegroup placement add  --rgw-zonegroup default --placement-id default-placement --storage-class cold.test
{
        "key": "default-placement",
        "val": {
            "name": "default-placement",
            "tags": [],
            "storage_classes": [
                "STANDARD",
                "cold.test"
            ]
        }
    }

为新存储类提供区放置信息：

语法

radosgw-admin zone placement add --rgw-zone default --placement-id PLACEMENT_TARGET --storage-class STORAGE_CLASS --data-pool DATA_POOL

示例

[root@rgw ~]# radosgw-admin zone placement add --rgw-zone default --placement-id default-placement --storage-class cold.test --data-pool test.cold.data

在数据池中启用 rgw 应用程序：

语法

ceph osd pool application enable POOL_NAME rgw

示例

[root@rgw ~] ceph osd pool application enable test.cold.data rgw
enabled application 'rgw' on pool 'test.cold.data'

重新启动所有 rgw 守护进程。

要查看区组群配置，请执行：

                "hot.test",
                "cold.test",

            ]
        }
    ],
    "default_placement": "default-placement",
    "realm_id": "",
    "sync_policy": {
        "groups": []
    }
}

要查看区配置，请执行：

语法

radosgw-admin zone get
{
    "id": "adacbe1b-02b4-41b8-b11d-0d505b442ed4",
    "name": "default",

            "key": "default-placement",
            "val": {
                "index_pool": "default.rgw.buckets.index",
                "storage_classes": {
                    "cold.test": {
                        "data_pool": "test.cold.data"
                    },
                    "hot.test": {
                        "data_pool": "test.hot.data"
                    },
                    "STANDARD": {
                        "data_pool": "default.rgw.buckets.data"
                    }
                },
                "data_extra_pool": "default.rgw.buckets.non-ec",
                "index_type": 0
            }
        }
    ],
    "realm_id": "",
    "notif_pool": "default.rgw.log:notif"
}

创建存储桶：

示例

[root@rgw ~]# aws s3api create-bucket --bucket testbucket10 --create-bucket-configuration LocationConstraint=default:default-placement --endpoint-url http://1x.7x.2xx.1xx:80

为生命周期配置创建 JSON 文件：
示例
```
[root@rgw ~]# vi lifecycle.json
```

在文件中添加特定的生命周期配置规则：

示例

{
    "Rules": [
        {
            "Filter": {
                "Prefix": ""
            },
            "Status": "Enabled",
            "Transitions": [
                {
                    "Days": 5,
                    "StorageClass": "hot.test"
                },
 {
                    "Days": 20,
                    "StorageClass": "cold.test"
                }
            ],
            "Expiration": {
                "Days": 365
            },
            "ID": "double transition and expiration"
        }
    ]
}

生命周期配置示例显示一个对象，它将在 5 天后从默认 STANDARD 存储类过渡到 hot.test 存储类，在 20 天后过渡到 cold.test 存储类，并在冷 .test 存储类中最终 365 天后过期。

在存储桶上设置生命周期配置：

示例

[root@rgw ~] aws s3api put-bucket-lifecycle-configuration --bucket testbucket20 --lifecycle-configuration file://lifecycle.json

检索存储桶上的生命周期配置：

示例

[root@rgw ~]aws s3api get-bucket-lifecycle-configuration --bucket testbucket20
{
    "Rules": [
        {
            "Expiration": {
                "Days": 365
            },
            "ID": "double transition and expiration",
            "Prefix": "",
            "Status": "Enabled",
            "Transitions": [
                {
                    "Days": 20,
                    "StorageClass": "cold.test"
                },
                {
                    "Days": 5,
                    "StorageClass": "hot.test"
                }
            ]
        }
    ]
}
