查看bucket下面的元数据列表

在ceph 10.2.9 下面操作，以修改Object名称为host的content_type属性为例，所有数据操作都有风险，请谨慎操作。

root@demohost:/home/demouser# radosgw-admin bi list --bucket=test[    {        "type": "plain",        "idx": "host",        "entry": {            "name": "host", #object名称            "instance": "",            "ver": {                "pool": 60,                "epoch": 1            },            "locator": "",            "exists": "true",            "meta": {                "category": 1,                "size": 254,                "mtime": "2017-08-30 07:46:16.956870Z",                "etag": "99a8629776211452eb4b9c3e6333a426",                "owner": "s3user",                "owner_display_name": "s3user",                "content_type": "text\/plain", #Object对应的content_type属性                "accounted_size": 254            },            "tag": "0a6967a5-2c76-427a-99c6-8a788ca25034.54133.2084",            "flags": 0,            "pending_map": [],            "versioned_epoch": 0        }    }]

查看对应Object的bucket元数据信息

root@demohost:/home/demouser# radosgw-admin bi get --bucket=test --object=host{    "type": "plain",    "idx": "host",    "entry": {        "name": "host",        "instance": "",        "ver": {            "pool": 60,            "epoch": 1        },        "locator": "",        "exists": "true",        "meta": {            "category": 1,            "size": 254,            "mtime": "2017-08-30 07:46:16.956870Z",            "etag": "99a8629776211452eb4b9c3e6333a426",            "owner": "s3user",            "owner_display_name": "s3user",            "content_type": "text\/plain",            "accounted_size": 254        },        "tag": "0a6967a5-2c76-427a-99c6-8a788ca25034.54133.2084",        "flags": 0,        "pending_map": [],        "versioned_epoch": 0    }}root@demohost:/home/demouser# radosgw-admin bi get --bucket=test --object=host > host.bi #导出(备份)到本地

修改对应Object的元数据

root@demohost:/home/demouser# cat host.bi{    "type": "plain",    "idx": "host",    "entry": {        "name": "host",        "instance": "",        "ver": {            "pool": 60,            "epoch": 1        },        "locator": "",        "exists": "true",        "meta": {            "category": 1,            "size": 254,            "mtime": "2017-08-30 07:46:16.956870Z",            "etag": "99a8629776211452eb4b9c3e6333a426",            "owner": "s3user",            "owner_display_name": "s3user",            "content_type": "jpg\/plain", #随便改了个jpg            "accounted_size": 254        },        "tag": "0a6967a5-2c76-427a-99c6-8a788ca25034.54133.2084",        "flags": 0,        "pending_map": [],        "versioned_epoch": 0    }}root@demohost:/home/demouser# radosgw-admin bi put --bucket=test --object=host < host.bi #导入修改后的内容(恢复)

查看修改结果
