通过EC2 1/2检查 [英] Ec2 1/2 checks passed
问题描述
自从今天我无法访问我的实例以来，我尝试停止并重新启动了几次，但状态始终是：已通过1/2次检查
Since today i can't access my instance, i tried stop and restart several times but the status is always : "1/2 checks passed"
创建快照，分离并重新附加新卷，但结果是相同的。
I tried to create a snapshot, detach and reattach new volume but the result is the same.
我还尝试创建另一个实例并附加该卷，但它也没有启动。
I also tried to create another instance and attach the volume and it's not starting either.
有帮助吗？
推荐答案
在亚马逊上自动执行状态检查EC2实例是：
The status checks automatically performed on Amazon EC2 instances are:
- 系统状态检查：这些检查Amazon EC2实例使用的基础系统
- 实例状态检查：这些检查特定实例的配置
- System Status Checks: These check the underlying systems used by the Amazon EC2 instance
- Instance Status Checks: These check the configuration of the specific instance
请参阅文档：您的实例的状态检查
通常，在这些检查完成之前，一个实例可用并且可以使用-Linux实例尤其如此，因为它们启动非常快。
Often, an instance is available and ready to be used before these checks are complete -- this is especially the case for Linux instances because they boot very quickly.
如果您收到通过 1/2支票的消息，请稍等一下或停止并启动实例。执行停止/启动将在另一个主机上启动实例，这可能会解决遇到的任何问题。
If you receive a 1/2 checks passed message, either wait a little longer or Stop and Start the instance. Performing a Stop/Start will launch the instance on a different host, which will probably fix whatever problem was being experienced.
如果 1/2停止/启动后，检查通过消息继续出现，这可能是AMI的配置错误。当从快照创建的AMI选择了错误的虚拟化类型时，我已经看到了这一点。
If the 1/2 checks passed message continues to appear after a Stop/Start, it is probably a misconfiguration of the AMI. I have seen this when the wrong virtualization type was selected for an AMI that was created from a Snapshot.
您可以通过使用操作菜单中的获取系统日志 命令，该命令在实例启动时显示日志。
You might be able to get a hint about the problem by using the Get System Log command in the Actions menu, which shows the log while the instance is booting.
最糟糕的情况是，从实例启动新实例。已知良好的AMI，将非引导卷作为附加磁盘附加，并将文件复制到新磁盘。即使文件无法启动，您仍然可以访问您的文件。
Worst case, launch a new instance from a known-good AMI, attach the non-booting volume as an additional disk and copy files to the new disk. You will still have access to your files even if it will not boot.
