What is "fslevel 5"? fslevel(8) only explains up to level 4. In fact it
even claims "Note that FFSv2 file systems are always level 4."

But I have 

# dumpfs /dev/rdk8
file system: /dev/rdk8
format  FFSv2
endian  little-endian
location 65536  (-b 128)
magic   19540119        time    Thu Jul  4 06:15:26 2019
superblock location     65536   id      [ xxxxxxxxxxxxxxxxx ]
cylgrp  dynamic inodes  FFSv2   sblock  FFSv2   fslevel 5
