【问题描述】：
我重新启动了拥有私有 Rocket.Chat 服务器的服务器，突然发现以 RC 开头的 mongo 实例出现以下问题：
[initandlisten] MongoDB starting : pid=12518 port=27017 dbpath=/var/snap/rocketchat-server/common 64-bit host=fight_club_wi

除了可能是最近对 mongo 的更新之外，我不确定是什么导致了该问题，但我认为这不会发生，因为我在过去 12 小时内没有看到任何表明更新的日志。
我目前在 Ubuntu 18.04 LTS 服务器上运行最新的稳定 Rocket Chat 版本。 Nginx 只是返回一个 502 Bad Gateway 错误，但我认为这是一个红鲱鱼，因为数据库不会加载，当我查询机器拥有的网站并且 Nginx 服务器指向该网站时工作正常。
因此我需要重新开始吗？
任何建议的帮助将不胜感激。

所以，我不知道发生了什么。我正准备听从 Max 的建议，但在此之前我想克隆驱动器以进行备份。克隆驱动器后，我将备份保存在原始机器中以确保它能够正确启动，并且'你瞧，现在数据库正在正确加载。我有点无语，但我想感谢大家的意见。
