我在AWS上有一个不运行Cent OS 7的AWS实例的备份/快照，我需要从该服务器获取我的数据（Mysql DB，php Files）。有什么可能的方法？
我尝试了一些方法，但这对我不起作用。
从实例创建一个图像，并从该图像/ ami创建一个新实例 结果：与之前相同（实例状态检查：失败）
从卷（15GB）创建快照，并将卷装入新的实例存储设备
结果：

答案 0 :(得分：0)
您是否已经使用mkfs.xfs之类的文件创建了文件系统？我遇到了与上述相同的问题，而这正是我所缺少的步骤。在将分区安装到目录之前，需要确保已为分区创建文件系统。
此外，我相信mount命令的-t标志仅指定分区是什么文件系统类型，而不是实际创建该文件系统类型。
