为什么我的MongoDB日志会填满“getmore local.oplog.rs”？

时间：2011-05-25 00:46:38

标签： logging mongodb replication

在MongoDB日志中反复重复这一过程。一些说明：

  • Ubuntu 11.04上的MongoDB 1.8.1
  • 副本集中的主要内容
  • 64gb磁盘
  • 5gb RAM
  • new Date(5610408224193773570)始终相同
  • verbose = true已在配置文件
    • 中注释掉

可能是我的oplog太大了，所以每次辅助查询都需要4秒钟？

答案 0 :(得分：3)

鉴于日期是相同的，它看起来像是辅助查询新的oplog条目而根本没有得到任何东西。您是否正在将任何数据写入主数据库？

这种行为看起来有点不寻常。但是，我只是通过启动副本集而不是写入它来获得同样的东西。你所看到的行为是预期的。
