Resize disk with umount

# umount device
sudo umount /archive

# resize part
sudo parted /dev/sdb resizepart 1 100%
# This may cause a message that the disk size has changed and the GPT table will need to be fixed.

# resize fs
sudo resize2fs /dev/sdb1

# If you need to check the FS use this command
# sudo e2fsck -f /dev/sdb1


sudo mount /dev/sdb1 /archive

# check fstab
# reboot and check
