mongo无法建索引?

Question

建索引的时候没有任何提示，一直提示正在建
通过mongosh键入：

db.currentOp().inprog.filter(x => x.waitingForLatch && x.waitingForLatch.captureName === 'IndexBuildsCoordinator::_mutex')

运行结果如下：

[
  {
    type: 'op',
    host: 'ubuntu:33090',
    desc: 'conn19931',
    connectionId: 19931,
    client: '111.111.111.111:12313',
    appName: 'MongoDB Compass',
    clientMetadata: {
      driver: [Object],
      os: [Object],
      platform: 'Node.js v14.16.0, LE (unified)|Node.js v14.16.0, LE (unified)',
      application: [Object]
    },
    active: true,
    currentOpTime: '2022-01-19T18:59:09.913+08:00',
    effectiveUsers: [ [Object] ],
    opid: 1956377797,
    lsid: {
      id: UUID("ab2ff5d3-1af8-4dc4-ade7-c7f742b9b22b"),
      uid: Binary(Buffer.from("13cbe34f636d20d83372568304ecc5d8a43ffa8b600aa27b0783e699fc7e6185", "hex"), 0)
    },
    secs_running: Long("12"),
    microsecs_running: Long("12180478"),
    op: 'command',
    ns: 'his.lc_hotel',
    command: {
      createIndexes: 'tt_09',
      indexes: [Array],
      lsid: [Object],
      '$clusterTime': [Object],
      '$db': 'his'
    },
    numYields: 0,
    waitingForLatch: {
      timestamp: 2022-01-19T10:58:57.833Z,
      captureName: 'IndexBuildsCoordinator::_mutex'
    },
    locks: { ReplicationStateTransition: 'w', Global: 'w' },
    waitingForLock: false,
    lockStats: {
      ParallelBatchWriterMode: [Object],
      ReplicationStateTransition: [Object],
      Global: [Object],
      Database: [Object],
      Collection: [Object],
      Mutex: [Object]
    },
    waitingForFlowControl: false,
    flowControlStats: { acquireCount: Long("2"), timeAcquiringMicros: Long("1") }
  }
]

可以通过db.killOp(opid)强行终止，不过还是无法新建索引
