There's your problem ^^^^^^^^

The MSDOS partition table format (aka DOS "MBR") is limited to 2TB and
behaves very strangely if you try to exceed that value. For devices
larger than 2TB you must use the GPT partition table format instead.

Parted does support GPT (see the mklabel command) but you will need to
back up the data from the device and re-create the partitioning scheme
and file system as the GPT format requires more reserved space at the
beginning of a device.
