由于DocTooLargeForCapped错误，mongorestore失败

Question

我试图像这样恢复一个集合：

$ mongorestore --verbose --db MY_DB --collection MY_COLLECTION /path/to/MY_COLLECTION.bson --port 1234 --noOptionsRestore

这里是错误输出（删除了时间戳）：

using write concern: w='majority', j=false, fsync=false, wtimeout=0

还原的结果是具有正确名称但没有文档的数据库和集合。

操作系统：在Azure VM上运行的Ubuntu 14.04。

我刚解决了自己的问题。见下面的答案。

Answer 1

问题似乎是我在副本集PRIMARY成员上使用mongod。

一旦我在/etc/mongod.conf中注释掉了以下一行，它就没有问题： replSet=REPL_SET_NAME - ＆gt; #replSet=REPL_SET_NAME

我假设将正确的副本集名称传递给mongorestore命令（如this question中）也可以，但尚未尝试过。
