我们在Docker容器中有一个副本集,其中包含三个节点,托管在支持每个mongodb数据节点的128 GB文件系统上的三台主机上。
每个mongodb容器都有5GB的内存限制和1,5个CPU限制,mongodb wiredTiger cacheSizeGB被定义为2.5。
遵循的升级过程与此处提供的文档相同:https://www.mongodb.com/docs/manual/release-notes/5.0-upgrade-replica-set/https://www.mongodb.com/docs/manual/release-notes/6.0-upgrade-replica-set/
在对不同版本的日志进行调查后,我发现版本4.4.8和5.0中存在此错误:
{"log":"{\"t\":{\"$date\":\"2023-03-04T16:22:54.348+00:00\"},\"s\":\"I\", \"c\":\"COMMAND\", \"id\":51803, \"ctx\":\"conn125400\",\"msg\":\"Slow query\",\"attr\":{\"type\":\"command\",\"ns\":\"local.oplog.rs\",\"command\":{\"find\":\"oplog.rs\",\"filter\":{},\"sort\":{\"-$natural\":1},\"lsid\":{\"id\":{\"$uuid\":\"9a02cb13-57ee-4793-a27d-ae51ef6774af\"}},\"$clusterTime\":{\"clusterTime\":{\"$timestamp\":{\"t\":1677946973,\"i\":2}},\"signature\":{\"hash\":{\"$binary\":{\"base64\":\"EBMoYzvf/BJE1tf1ghz6ZkQ+E2Y=\",\"subType\":\"0\"}},\"keyId\":7206450133318238212}},\"$db\":\"local\",\"$readPreference\":{\"mode\":\"primaryPreferred\"}},\"planSummary\":\"COLLSCAN\",\"numYields\":71,\"queryHash\":\"A11B6D23\",\"planCacheKey\":\"A11B6D23\",\"ok\":0,\"errMsg\":\"Executor error during find command :: caused by :: Sort exceeded memory limit of 104857600 bytes, but did not opt in to external sorting.\",\"errName\":\"QueryExceededMemoryLimitNoDiskUseAllowed\",\"errCode\":292,\"reslen\":378,\"locks\":{\"ReplicationStateTransition\":{\"acquireCount\":{\"w\":72}},\"Global\":{\"acquireCount\":{\"r\":72}},\"Database\":{\"acquireCount\":{\"r\":72}},\"Mutex\":{\"acquireCount\":{\"r\":1}},\"oplog\":{\"acquireCount\":{\"r\":72}}},\"storage\":{},\"protocol\":\"op_msg\",\"durationMillis\":105}}\r\n","stream":"stdout","time":"2023-03-04T16:22:54.349177116Z"}
此错误涉及以下命令:“命令”:{“查找”:“oplog.rs“,“筛选器”:{},“排序”:{"-$natural”:1}
它失败的原因是结果太大,无法存储在内存中,并且在版本4.4.8和5.0中,默认情况下禁用写入磁盘,这与版本6.0不同。在我的示例中,正是此命令导致在版本6.0中填充磁盘。我不知道是哪个事件导致执行此命令。
我想这个事件是由于复制或选举过程不同步,导致每个节点上的数据恢复的OPLOG阅读,但这个过程是mongodb的正常过程吗?
我必须设置一个特定的配置,让这个进程正常运行,而不必在磁盘上序列化吗?是否可以限制Mongo写入驱动器的临时文件的大小?我的mongodb集群大小是否错误?
我们重新启动了从4.4.8到6.0.4的迁移过程,但始终遇到相同的问题。

问题解决了,这些请求是由于我的监控解决方案metricbeat及其模块mongodb,更准确地说是模块replstatus。
https://github.com/elastic/beats/blob/main/metricbeat/module/mongodb/replstatus/info.go
https://github.com/elastic/beats/issues/33616
要解决此问题,请禁用mongodb metricbeat模块中的replstatus模块
