我有一个我正在尝试恢复的单个集合的现有 mongodump。运行 mongo restore 后,没有出现错误,并且数据不在集合中。是否有任何已知的原因会发生这种情况?我希望如果由于某种原因没有插入数据,日志中会出现错误。

为了创建并尝试恢复转储,我遵循了为这个问题提供的答案: How to use mongodump for 1 collection

我在另一台服务器上创建了一个新数据库,它有一个空集合。我检查了 mongo 日志文件,没有错误,它显示连接打开并进行身份验证,然后在下一行断开连接。

mongorestore -vvvvv -u user -p 'password' --db=MyDatabase --collection=MyCollection dump1/MyCollection.bson

日志文件:

2015-03-04T18:20:31.333+0000 [conn874]  authenticate db: MyDatabase { authenticate: 1, nonce: "xxx", user: "user", key: "xxx" }
2015-03-04T18:20:31.342+0000 [conn874] end connection 127.0.0.1:59420 (25 connections now open)

我在起点和终点上使用的查询是:

db.MyCollection.find()

在源服务器上,该集合有 130 个元素,这也显示在 mongorestore 输出“找到 130 个对象”中。

编辑:

我将--drop选项添加到 mongorestore 命令。日志文件输出清楚地表明它正在为空集合创建索引。

所以问题最终是我试图进行恢复的用户只有 read 和 dbAdmin 角色。我创建了一个单独的用户,因此应用程序使用的普通用户没有管理权限。将我的用户角色从 read 更改为 readWrite 后,它按预期工作。

老实说,如果用户没有正确的权限,我真的希望日志在尝试在没有正确权限的情况下运行还原时显示某种错误。
