我有一个在 Windows 上运行的 MongoDB 3 成员副本集。当主服务器 (S1) 出现故障时，将正确选择辅助服务器。当主服务器恢复时，副本成员保持无效状态:
{
"state" : 10,
"stateStr" : "REMOVED",
"uptime" : 111,
"optime" : Timestamp(1448462710, 6),
"optimeDate" : ISODate("2015-11-25T14:45:10Z"),
"ok" : 0,
"errmsg" : "Our replica set config is invalid or we are not a member of it",
"code" : 93
}
之后，secondary，每隔几秒就不停地在primary和secondary之间切换，让我的应用不稳定。
恢复主服务器的唯一方法是执行 rs.reconfig(c)。
我找不到配置文件有什么问题。
我们将不胜感激。
更新: 这是当前配置:

我应该使用 IP 地址而不是主机名吗？
更新 2:
这是主服务器(m3.companyName.com - IP 1.1.1.1)的日志，从它重新启动开始，直到我进入另一台服务器(m2.companyName.com - IP 2.2.2.2)并执行手动 rs.reconfig()。
