XFS filesystem cannot be mounted after changing the uuid using xfs_admin from xfsprogs-4.5 on RHEL

Solution Unverified - Updated -


After updating the filesystem uuid with xfs_admin from xfsprogs-4.5 I am unable to mount the filesystem.

# xfs_admin -U generate xfs_test.image 
Clearing log and setting UUID
writing all SBs
new UUID = c530847f-42eb-4719-9d00-a0ae11e1d635
# mount xfs.image /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

# dmesg -t | tail
XFS (loop0): Superblock has unknown incompatible features (0x4) enabled.
Filesystem can not be safely mounted by this kernel.
XFS (loop0): SB validate failed with error -22.
