There is 80GB on sda3. 40GB occupies the vg-ubuntu--lv partition under /which is completely full.
The rest of the memory on sda3 (also about 40) is free and is not used by the directory (as I understand it). I want to take advantage of these remaining unallocated GBs.
It doesn't really matter whether it's a new directory or an extension of an existing one. I just need this memory. Heavy software installation required.
Tell me how I can better solve this problem.
