如何找到一個索引構建操作

Question

我想添加一個索引集合（data_04）的OPID，但之後執行它在蒙戈外殼

mongos> db.data_04.createIndex({"column1":1, "column":1,cacheDataTime:1 }) 

，但相當長的一段時間後，它仍然沒有還未完成。所以我想明確殺死它並在後臺創建它。但我首先要知道它的opid，我嘗試下面的方法都沒什麼輸出

# The following example returns information on index creation operations: 
mongos> db.currentOp(
...  { 
...  $or: [ 
...   { op: "query", "query.createIndexes": { $exists: true } }, 
...   { op: "insert", ns: /\.system\.indexes\b/ } 
...  ] 
...  } 
...) 

"inprog" : [ ], 
"ok" : 1 

mongos> db.currentOp(
... { 
...  "active" : true, 
...  "ns" : /data_04/ 
... } 
...) 

"inprog" : [ ], 
"ok" : 1 

那麼，什麼是錯的，以及如何找到一個索引創建操作的OPID？

Answer 1

在我的情況下，它應該是

db.currentOp(
    { 
     $or: [ 
     { op: "command", "query.createIndexes": { $exists: true } }, 
     { op: "insert", ns: /\.system\.indexes\b/ } 
     ] 
    } 
)

       }, 
       "name" : "column1_1_column_1_cacheDataTime_1", 
       "background" : true 
      } 
     ] 
    },
