I just built my new server and realized that I accidentally only allotted 200GB to Ubuntu leaving the remaining 1.8TB unusable on my server. I have already tried partitioning using sudo to resize the partition, but I got an error saying that the resource was busy. I attached a screenshot for reference. I also am only using a terminal so no GUI solutions will work.
