The man page for mkfs.ext4 describes an
optional command line parameter, -f, to
specify fragment size. However, this option was removed when
support for creating bigalloc file systems
was added. Attempts to create an ext4 file
system with the mkfs.ext4 command in
conjunction with this option may result in an error notifying
the user of an invalid option. (Bug ID 25512202)
