The HD size is being shown incorrectly 2TB instead of 4TB

I have a 4TB HD that was recognized correctly on the old Umbrel. After installing version 1.1, despite having recognized 4TB before installation, Umbrel only displays 2TB. I installed parted and verified that the result for parted --list is:

1 8389kB 218MB 210MB fat16 ESP boot, esp
2 218MB 10.8GB 10.6GB ext4 primary
3 10.8GB 21.3GB 10.6GB ext4 primary
4 21.3GB 4001GB 3979GB ext4 primary

fdisk -l shows basically the same thing:
Device Start End Sectors Size Type
/dev/sda1 16384 425983 409600 200M EFI System
/dev/sda2 425984 21037055 20611072 9.8G Linux filesystem
/dev/sda3 21037056 41648127 20611072 9.8G Linux filesystem
/dev/sda4 41648128 7814037127 7772389000 3.6T Linux filesystem

And df -h shows something different:

udev 3.9G 0 3.9G 0% /dev
tmpfs 784M 2.3M 781M 1% /run
/dev/sda2 9.6G 3.7G 5.5G 41% /
tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
/dev/sda1 200M 46M 154M 23% /boot/efi
/dev/sda4 1.8T 676G 1.1T 38% /data
overlay 1.8T 676G 1.1T 38% /var/lib/docker/overlay2…
(This one appears 16 times!)
tmpfs 784M 0 784M 0% /run/user/1000

What could be happening for Umbrel to only display 2TB?

Thanks.
