如何解决增加卷大小 AWS EC2 后，Ubuntu 18.04 Mailcow 安装无法启动
我们在 AWS EC2 上安装了 Mailcow。之前的卷有 40GB，当我们看到 df 使用率达到 100% 时修改为 60GB。
在卷大小增加后，更改没有反映出来，因此我们重新启动了服务器（我们通常在 GCP 中这样做，而且效果很好）。
重启服务器后，服务器根本没有启动。
AWS 中的实例日志显示 - 设备上没有剩余空间。
因此，我们将此卷分离并连接到另一台服务器作为辅助存储，并将一些文件复制到另一个“备份”卷，以便我们在主服务器启动后恢复文件。
现在，我们卸载了旧卷并将其附加到主服务器，我们得到了以下实例日志。
SSH 仍然无法连接。

我们可以看到存储卷已经挂载，所以这不是问题。
有人遇到过同样的问题吗？任何帮助将不胜感激。
解决方法
如果它对某人有帮助。当磁盘空间因收到的电子邮件而被填满时，MailCow 的问题就开始了。这可能是由于垃圾邮件爆炸占用了服务器空间。因此，Linux 操作系统无法启动。即使使用 SSH 我也无法连接。事实证明，即使要调整磁盘大小，您也需要磁盘上不存在的一些可用空间。
已按照以下步骤纠正问题：
-
磁盘已与旧服务器分离。在继续之前，我还创建了该磁盘的快照。
-
在 AWS 上创建了一个新实例。安装了 Ubuntu 并完成了 Mailcow 的全新安装。这次的主盘比旧服务器大很多。
-
现在旧服务器磁盘已附加到新服务器并挂载，以便可以将旧文件复制到新安装中。
-
此外，遵循 Mailcow 文档中提到的步骤。 https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_migration/
如果有人在这方面需要任何帮助，请随时与我联系。我挠了三天三夜才把它修好。我几乎什么都试过了:)
