Yes, I already ran into such an issue a few years ago. I mounted a disk
created ext4 with a newer Debian on a machine running an older Debian
and it would not mount (at all). I looked it up in a script I made and
for me it was the metadata_csum option that was inserted by the newer
Debian and the old one did not support this. So the trick was to format
the disk without that option:

---------- 8< -------------

mkfs.ext4 -O '^metadata_csum' /dev/mmcblk0p3 </usr/bin/yes || exit 1

---------- 8< -------------

Did you format the disk with a newer system than the system you run it
on? So, I wonder what happens if you remove the huge_file option

tune2fs -O '^huge_file' /dev/disk

The ^ means you remove it IIRC. And be sure you have no files bigger
than 2TB. I strongly recommend to create a backup before playing with
tune2fs ;-)
