我尝试将一个现有的EBS存储（有数据）挂载到一个实例，但是一直抛出这个错误。
mount: wrong fs type, bad option, bad superblock on /dev/xvdf, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so. 存储的细节是：
ec2-user@ip ~]$ sudo parted -l Model: Xen Virtual Block Device (xvd) Disk /dev/xvda: 8590MB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 128 1049kB 2097kB 1049kB BIOS Boot Partition bios_grub 1 2097kB 8590MB 8588MB ext4 Linux Model: Xen Virtual Block Device (xvd) Disk /dev/xvdf: 16.1GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 128 1049kB 2097kB 1049kB BIOS Boot Partition bios_grub 1 2097kB 16.1GB 16.1GB ext4 Linux
dmesg | 尾部显示以下细节

看起来像你已经分区该块设备。 在这种情况下，您需要挂载/dev/xvdf1 ，而不仅仅是/dev/xvdf 。
