我们有两个副本集和一个artiber节点。在副本集中，一个被指定为主要的，另一个被指定为次要的。当其中一个关闭时，另一个人将自动接管为主要人员。但在不可预见的情况下，当主要和次要都关闭时（也是仲裁者），当我们重新启动它们时，rs.status显示为SECONDARY。他们都没有当选为主要人选。 rs.status显示如下错误（注意：我们尝试手动更改pri / secondary节点的优先级。我们使用mongodb版本2.0和--keyfile进行身份验证。所有基本检查都进行了初步调试，但目前还没有线索）。请建议。

否则，这可能是https://jira.mongodb.org/browse/SERVER-3929的错误，由https://jira.mongodb.org/browse/SERVER-3715在2.0.2中修复（在撰写本文时尚未发布）。
SERVER-3929案例中的一些用户报告说重启节点有帮助。
答案 1 :(得分：0)
我发现此问题的解决方法是在激活身份验证之前创建管理员用户（在连接到管理数据库时在shell中使用db.addUser）。
