You are creating a file system on the raw device, not on a partition. I
don't know if this is relevant or not, just that it's an uncommon
practice.

What I think is happening -- or, rather, not happening -- is "mke2fs -t
ext4" creates an ext4 file system without journaling since you didn't
specify "-j" and "-J <options>", and you didn't use mkfs.ext4 which
provides reasonable default options for ext4 file systems.
