mongodb - MongoDB分片问题

Question

我们的 mongodb 服务器部署了 2 个分片，每个分片有 1 个主服务器和 2 个从服务器。四个从服务器运行 mongo config 作为代理，两个从服务器运行仲裁器。但是mongodb现在不能用了。

我可以连接到 192.168.0.1:8000(mongos) 并执行诸如“使用数据库”或“显示 dbs”之类的查询，但我无法在选定的数据库中执行查询，例如“db.foo.count()”、“ db.foo.findOne()'

这是错误日志：

mongos> db.dev.count()
Fri Aug 16 12:55:36 uncaught exception: count failed: {
    "assertion" : "DBClientBase::findN: transport error: 10.81.4.72:7100 query: { setShardVersion: \"\", init: true, configdb: \"10.81.4.72:7300,10.42.50.26:7300,10.81.51.235:7300\", serverID: ObjectId('520db0a51fa00999772612b9'), authoritative: true }",
    "assertionCode" : 10276,
    "errmsg" : "db assertion failure",
    "ok" : 0
}

我只能在 mongos 上启动，如果同时运行 1 个以上的 mongos，则不会执行查询，错误日志：
