我們的mongodb服務器部署有2個分片,每個分片有1個主服務器和2個從服務器。 四臺從服務器運行mongo config作爲代理,兩臺從服務器運行仲裁器。 但是現在mongodb coundn't。MongoDB分片問題
我可以連接到192.168.0.1:8000(mongos)和exec查詢,如'use database'或'show dbs',但是我不能在選擇的數據庫中執行查詢,如'db.foo.count( )」, 'db.foo.findOne()'
以下是錯誤日誌:
mongos> db.dev.count()

我只能在mongos開始,查詢不會EXEC如果超過1個mongos在運行同時錯誤日誌:

沒有之前的工作?你有沒有改變配置中的任何東西?你是如何設置副本集的? – Tilo
從運行mongos的服務器,你可以嘗試直接通過mongo shell作爲第一個測試來連接到每個mongods(config和master)嗎?另外,爲什麼您使用主/從配置超過副本集? –
我只能在mongos上啓動,如果超過1個mongos同時運行,查詢將不會執行,錯誤日誌:mongos> db.dev.count() Fri Aug 16 15:12:29未捕獲的異常:count失敗:{ \t「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:物件( '520dd04967557902f73a9fba'),權威:真正}」, \t 「assertionCode」:10276, \t 「ERRMSG」: 「DB斷言失敗」, \t「OK 「:0 } –
