Question

我正在分片环境的新数据库中创建一个新集合。

我在coll.insertMany(list)时收到以下错误。

Exception in thread "main" com.mongodb.MongoCommandException: 
Command failed with error 133: 'unable to target write op for collection dbname.collection:: caused by ::

Answer 1

看起来Read Preference正在制造问题。

请通过阅读偏好设置并设置哪个更适合您的应用

https://docs.mongodb.com/manual/reference/read-preference/

如果您的问题与下面jira中提到的问题有关，那么我们需要mongo版本3.3.11，目前我们只有3.2.9 released。

Answer 2

在您的情况下，只读首选项成员可能在副本集中不可用，即主数据库不可用。

出于一个或多个原因。

当newely初级是越来越当选故障转移的情况。
大多数服务器不可用，没有主要服务器可用。
