Probably because mkfs.ext4 is still limited to 16 TB. Per
, "current e2fsprogs currently still limits the filesystem size to 2^32
blocks (16T for a 4k block filesystem). Filesystems larger than 16T is
one of the very next high-priority features to complete for ext4. "
also says 16 TB filesystems are not yet available.
