我试着将一个现有的EBS存储（有数据）挂载到一个实例，但是它一直抛出这个错误。
mount: /dev/xvdf1 is write-protected, mounting read-only mount: unknown filesystem type '(null)' 这些是存储的细节：
Model: Xen Virtual Block Device (xvd) Disk /dev/xvda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: pmbr_boot Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 10.7GB 10.7GB xfs Model: Xen Virtual Block Device (xvd) Disk /dev/xvdf: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: pmbr_boot Number Start End Size File system Name Flags 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 10.7GB 10.7GB xfs
我怎样才能挂载分区？
