When trying to mount can XFS filestsen on an AWS instance, I got the error “mount: wrong fs type, bad option, bad superblock on /dev/sdh”

Examine the volume’s UUID with the xfs_db command:

shell> sudo xfs_db -c uuid /dev/nvme2n1

To fix the problem, you have two options…

Temporary Solution

Add nouuid mount option to temporarily ignore the duplicate validation:

shell> sudo mount -t xfs -o nouuid /dev/nvme2n1 /volumes/tmp

Permanent Solution

The xfs_admin command can permanently adjust the UUID for the volume:

shell> sudo xfs_admin -U generate /dev/nvme2n1
Clearing log and setting UUID
writing all SBs
new UUID = 5eb71513-2d234-4b79-9a35-f22f2974672d

shell> sudo xfs_admin -U generate /dev/nvme2n1

Clearing log and setting UUID

writing all SBs

new UUID = 5eb71513-2d234-4b79-9a35-f22f2974672d
