MongoDB副本集成员状态为“其他". [英] MongoDB Replica Set Member State is "OTHER"

问题描述

三名成员，主要成员和二级-第三个是"OTHER"-我找不到关于该状态的任何信息，不确定该怎么做，我已经重新启动了实例，但是总是出现相同的情况.在该状态下找不到任何文档.

Three members, primary & secondary - and a third one that's "OTHER" - I can't find any info on that state, not sure what to do, I've restarted the instance, but it always comes-up the same. Can find no documentation on that state.

我是副本集的新手，我们将不胜感激.

I'm new to replica sets - and any help would be appreciated.

推荐答案

配置未正确设置.

您可以使用以下命令进行初始化:

You can use following command to init:

rs.initiate({
      _id: "rs0",
      version: 1,
      members: [
         { _id: 0, host : "localhost:27017" }
      ]
   }
)

如果您已经启动，则可能会收到像我这样的错误消息:

If you have already initiated, you may get the error msg like me:

singleNodeRepl:OTHER> rs.initiate({ _id: "rs0", members: [ { _id: 0, host : "localhost:27017" } ] } )
{
    "info" : "try querying local.system.replset to see current configuration",
    "ok" : 0,
    "errmsg" : "already initialized",
    "code" : 23,
    "codeName" : "AlreadyInitialized"
}

解决方案是reconf mongo:

The solution is to reconf the mongo:

singleNodeRepl:OTHER> rsconf = rs.conf()
singleNodeRepl:OTHER> rsconf.members = [{_id: 0, host: "localhost:27017"}]
[ { "_id" : 0, "host" : "localhost:27017" } ]
singleNodeRepl:OTHER> rs.reconfig(rsconf, {force: true})
{ "ok" : 1 }
singleNodeRepl:OTHER>
singleNodeRepl:SECONDARY>
singleNodeRepl:PRIMARY>
