恢复到副本集时挂起Mongorestore

mongodb

slipset · 技术社区 · 6 年前

使用以下.mongorc.js:

rs.slaveOk();

function startRS() {
    config = {_id: 'rs', members: [{_id: 0, host: 'localhost:27017', priority: 1}, {_id: 1, host: 'localhost:27016', priority: 0}]};
    rs.initiate(config);
}

以及以下启动脚本:

#!/bin/bash

mkdir /data/db/rs{0,1} >/dev/null 2>&1

/opt/mongo-db/bin/mongod --replSet rs --port 27016 --dbpath /data/db/rs1 &

/opt/mongo-db/bin/mongod --replSet rs --port 27017 --dbpath /data/db/rs0 &

/opt/mongo-db/bin/mongo --eval "startRS()"

Mongo开始一切正常。但是当我试着用

$ /opt/mongo-db/bin/mongorestore  --drop dump/

它在不停地写着的时候挂着

这是MacOS High Sierra上的MongoDB-OSX-x86_64-Enterprise-3.6.5

我已经在另一台Mac上运行了这个精确的设置(可能不太精确,因为它正在工作),也有MacOS High Sierra,但可能有MongoDB-3.6.4。

有什么建议吗?

mongorestore命令行正在默认端口上连接到本地主机上的一个独立mongod,您发布的日志片段指示一个无法进行写入的辅助节点。

为了使MonoRestore自动切换到可写节点,您需要在命令行中指定副本集

connection options:
-h, --host=<hostname>                                     mongodb host to connect to (setname/host1,host2 for replica sets)
--port=<port>                                         server port (can also use --host hostname:port)
