在初始启动时设备上没有任何空间，而且我丢失了pem密钥文件，因此无法使用ssh。

Question

我被困在一个奇怪的情况下，因为，我失去了aws键和设备空间是满的。我已经为该实例创建了一个AMI，并启动了一个新实例。但没办法。我从AWS控制台面板中检查了系统日志，我可以看到许多日志都说在设备上没有空间。

我需要找出我的数据库。我试过以下几点：

1. 创建了一个AMI，并使用更多的内存和更多的磁盘空间启动新实例，但系统日志仍然没有打印设备在启动实例时留下的空间。
2. 试图与会话管理器连接，但在目标实例部分中没有列出实例。我在新的新实例中附加了相同的AMI角色，SSM登录很好。
3. i试图使用用户数据脚本清除tmp文件。但是用户数据脚本在这个实例上不起作用。我已经在其他实例上测试了这个脚本，所以脚本中没有错误.

系统日志如下：

Answer 1

看一下日志，我希望如果系统完全完成引导，系统就会非常坏。这可能会限制你的选择。我可以想出两个办法来尝试：

1. 当您从AMI恢复时，您可以指定一个不同的键(即创建一个新的键盘)--您试过了吗？如果磁盘是完全满的，这可能不起作用--不确定。这可能是一个简单的解决方法，尽管值得尝试。

1. 更激烈的选择是克隆已损坏的实例磁盘(即:将AMI的快照恢复为新的ebs卷&增加其大小)。然后创建一个新的临时ec2实例，并将EBS卷副本作为第二个驱动器附加。启动并登录到临时VM，这样您就可以删除文件/调整磁盘和分区，或者只提取数据/配置文件。
