我花了一周时间让自由职业者创建的 Mongo 4.4 PSA 副本能够工作。我放弃了，从所有三台服务器中删除了完整的 mongod 并按照Mongo doc从头开始安装。唯一的更改是在副本初始化之前创建新数据库并导入数据。
第一次失败（连接超时），我重新审视了我的防火墙规则。然后它立即连接并在所有节点上刷新 mongo shell：
rs_bud:SECONDARY> show collections
rs_bud:PRIMARY> use bud
但是当我对辅助节点执行任何操作时，它们会因NotPrimaryNoSecondaryOk错误而失败。
rs_bud:SECONDARY> use bud
rs_bud:SECONDARY> show collections
uncaught exception: Error: listCollections failed: {
