我试图设置一个具有两个节点的副本集:Node0和Node1.从Node0我初始化了一个名为"rs0"的副本集,并将Node1添加到它.问题是它被添加为主节点而不是辅助节点,最终结果是具有两个主节点的副本集.
这是rs.status()从Node0 执行命令的结果
"set" : "rs0",
"date" : ISODate("2012-10-23T21:03:37Z"),
"myState" : 1,
"members" : [
{
"_id" : 0,
"name" : "Node0:27017",
"health" : 1,
"state" : 1,
"stateStr" : "PRIMARY",
"uptime" : 61185,
"optime" : Timestamp(1350967947000, 1),
"optimeDate" : ISODate("2012-10-23T04:52:27Z"),
"self" : true
},
{
"_id" : 1,
"name" : "Node1:27017",
"health" : 1,
"state" : 1,
"stateStr" : "PRIMARY",
"uptime" : 58270,
"optime" : Timestamp(1350956423000, 1),
"optimeDate" : ISODate("2012-10-23T01:40:23Z"),
"lastHeartbeat" : ISODate("2012-10-23T21:03:37Z"),
"pingMs" : 0
} …我在 Python 中的库 AIOKafka 遇到了错误（版本在最后）。基本上，我收到一条失败的心跳消息，然后无法执行偏移量的提交。这是日志：
