推荐答案

您需要做的是挂载旧卷上的新实例。进入亚马逊EC2控制面板，然后单击卷（下弹性块存储）。看看附件信息老EBS卷。这将是类似于＆LT;实例ID＆GT; （小于实例名称＆gt;）是：/ dev / SDG

What you need to do is mount the old volume on the new instance. Go to the Amazon EC2 control panel, and click "Volumes" (under Elastic Block Store). Look at the attachment information for the old EBS volume. This will be something like <instance id> (<instance name>):/dev/sdg

请记下这里给出的路径，这样会是/ dev / SDG在上面的例子。然后使用SSH和连接到新的实例，然后键入的mkdir到/ mnt / oldvolume 然后设置/ dev / SDG的/ mnt / oldvolume （或者在控制面板中给出的路径是）。您的文件现在应该在的/ mnt / oldvolume 可用。如果这没有解决您的问题，请重新用你的东风命令的输出做了这一切之后发布。

Make a note of the path given here, so that'd be /dev/sdg in the example above. Then use SSH and connect to your new instance, and type mkdir /mnt/oldvolume and then mount /dev/sdg /mnt/oldvolume (or whatever the path given in the control panel was). Your files should now be available under /mnt/oldvolume. If this does not solve your problem, please post again with the output of your df command after doing all of this.

因此​​，要回顾一下，对一个实例使用EBS卷，您需要使用控制面板（或API工具）将其连接到该实例，而则的将其安装在该实例本身。

So, to recap, to use an EBS volume on an instance, you need to attach it to that instance using the control panel (or API tools), and then mount it on the instance itself.
