MongoDB分片数据库partitioned属性始终为false问题求助

环境信息 #

• MongoDB版本：6.0.4
• Mongosh版本：1.8.0
• 本地通过不同端口搭建分片集群，执行sh.status()得到的集群配置如下：

[direct: mongos] test> sh.status()
shardingVersion
{
  _id: 1,
  minCompatibleVersion: 5,
  currentVersion: 6,
  clusterId: ObjectId("643fd1088dc14852e495a094")
}
---
shards
[
  {
    _id: 'shard001',
    host: 'shard001/127.0.0.1:27117,127.0.0.1:27118,127.0.0.1:27119',
    state: 1,
    topologyTime: Timestamp({ t: 1681904960, i: 7 })
  },
  {
    _id: 'shard002',
    host: 'shard002/127.0.0.1:27217,127.0.0.1:27218,127.0.0.1:27219',
    state: 1,
    topologyTime: Timestamp({ t: 1681904968, i: 8 })
  },
  {
    _id: 'shard003',
    host: 'shard003/127.0.0.1:27317,127.0.0.1:27318,127.0.0.1:27319',
    state: 1,
    topologyTime: Timestamp({ t: 1681904975, i: 6 })
  }
]

已执行操作及结果 #

1. 创建sharddb数据库，以及user、users两个集合
2. 执行sh.enableSharding("sharddb")为数据库开启分片
3. 为两个集合配置分片并插入数据，相关配置及数据分布结果如下：

{
    database: {
      _id: 'sharddb',
      primary: 'shard002',
      partitioned: false,
      version: {
        uuid: new UUID("e2603a9b-53e3-4ecd-8ef9-f35786431451"),
        timestamp: Timestamp({ t: 1682148090, i: 1 }),
        lastMod: 1
      }
    },
    collections: {
      'sharddb.user': {
        shardKey: { name: 1 },
        unique: false,
        balancing: true,
        chunkMetadata: [ { shard: 'shard002', nChunks: 1 } ],
        chunks: [
          { min: { name: MinKey() }, max: { name: MaxKey() }, 'on shard': 'shard002', 'last modified': Timestamp({ t: 1, i: 0 }) }
        ],
        tags: []
      },
      'sharddb.users': {
        shardKey: { name: 'hashed' },
        unique: false,
        balancing: true,
        chunkMetadata: [
          { shard: 'shard001', nChunks: 2 },
          { shard: 'shard002', nChunks: 2 },
          { shard: 'shard003', nChunks: 2 }
        ],
        chunks: [
          { min: { name: MinKey() }, max: { name: Long("-6148914691236517204") }, 'on shard': 'shard001', 'last modified': Timestamp({ t: 1, i: 0 }) },
          { min: { name: Long("-6148914691236517204") }, max: { name: Long("-3074457345618258602") }, 'on shard': 'shard001', 'last modified': Timestamp({ t: 1, i: 1 }) },
          { min: { name: Long("-3074457345618258602") }, max: { name: Long("0") }, 'on shard': 'shard002', 'last modified': Timestamp({ t: 1, i: 2 }) },
          { min: { name: Long("0") }, max: { name: Long("3074457345618258602") }, 'on shard': 'shard002', 'last modified': Timestamp({ t: 1, i: 3 }) },
          { min: { name: Long("3074457345618258602") }, max: { name: Long("6148914691236517204") }, 'on shard': 'shard003', 'last modified': Timestamp({ t: 1, i: 4 }) },
          { min: { name: Long("6148914691236517204") }, max: { name: MaxKey() }, 'on shard': 'shard003', 'last modified': Timestamp({ t: 1, i: 5 }) }
        ],
        tags: []
      }
    }
  }

问题描述 #

尽管已执行sh.enableSharding("sharddb")，且两个集合已配置分片（其中users集合的分片数据已分布到三个shard），但sharddb数据库的partitioned属性始终显示为false。再次执行sh.enableSharding("sharddb")返回成功，但查询db.databases.find()的结果仍显示该属性为false：

[direct: mongos] config>  sh.enableSharding("sharddb");
{
  ok: 1,
  '$clusterTime': {
    clusterTime: Timestamp({ t: 1683086356, i: 1 }),
    signature: {
      hash: Binary(Buffer.from("0000000000000000000000000000000000000000", "hex"), 0),
      keyId: Long("0")
    }
  },
  operationTime: Timestamp({ t: 1683086356, i: 1 })
}
[direct: mongos] config> db.databases.find()
[
  {
    _id: 'sharddb',
    primary: 'shard002',
    partitioned: false,
    version: {
      uuid: new UUID("e2603a9b-53e3-4ecd-8ef9-f35786431451"),
      timestamp: Timestamp({ t: 1682148090, i: 1 }),
      lastMod: 1
    }
  },
]

寻求解决该问题的方法。
