XFS: wrong fs type, bad option, bad superblock

Question

My AWS Linux 2 instance boot drive is snapshotted daily. I'd like to mount one of the snapshots to my instance to review changes I've made in /etc. I created a volume based on the snapshot, attached to my instance and tried to mount it. I used df -T to determine my existing boot drive filesystem is xfs. I presume my snapshot is xfs. I can't seem to mount it. I tried with several of the snapshots. Am I trying to do something weird, adding a second bootable drive to my instance?

mount /dev/xvdi1 /mnt/tmp
mount /dev/xvdi1 /mnt/tmp -t xfs
mount -t xfs /dev/xvdi1 /mnt/tmp

**mount: /mnt/tmp: wrong fs type, bad option, bad superblock on /dev/xvdi1, missing codepage or helper program, or other error.**

**from fdisk -l:**
Disk /dev/xvdi: 16 GiB, 17179869184 bytes, 33554432 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: EB7656A9-A5D7-4AAF-B8A8-67A3FBEC56BA

Device       Start      End  Sectors Size Type
/dev/xvdi1    4096 33554398 33550303  16G Linux filesystem
/dev/xvdi128  2048     4095     2048   1M BIOS boot

Answer

Hi there ,I understand that you would like to mount the volume that you created and now you are unable to mount it.Correct me if I misunderstood.

Based on the tests that I ran you will need to :
[1]create  a snapshot
[2]attach it to a volume
[3]Stop the instance that you want to mount the volume to
[4]attach the volume of the snapshot to your rescue instance
[5]SSH into the rescue instance
[6]Run this command < lsblk -f > to check the name of the disk you want to mount
[7]run the following command to mount
[7.1] mount -o nouuid  /dev/ /data

I have provided you with additional documentation under the reference section.

I hope this was helpful!

You might have found your way around.  Just in case someone stumbles upon the same issue:
Try running mount -o nouuid  /dev/xvdi1 /mnt/tmp r. Just in case someone stumbles upon same issue:
