Question

在我的应用程序中，我正在对Mongodb集合执行以下查询。它会将collection的所有记录移至his_collection

`for record in collection.find():
    his_collection.insert(record)

 collection.remove()`

在collection表中使用 3k 行，它可以正常工作，即所有行都移动到his_collection。

但是当我在collection中使用 10k 行执行上述命令时。它被绞死了

现在，当我尝试将Mongodb与命令mongo连接到shell时，它会抛出错误

MongoDB shell version: 2.4.5
connecting to: test
Fri Aug 23 12:41:28.762 JavaScript execution failed: Error: couldn't connect to
server 127.0.0.1:27017 at src/mongo/shell/mongo.js:L112
exception: connect failed

我尝试在shell中执行以下命令来解决此问题

service mongodb stop
rm /mnt-data/data/mongodb/mongod.lock
mongod –repair --dbpath=/mnt-data/data/mongodb/
service mongodb start

请建议我有什么建议吗？

您需要添加更多磁盘空间。我已经看到修复从2x datasize运行到50x datasize - 取决于数据损坏的严重程度。
