What can I do during install of ubuntu server 18.04.5 to take all that I allocate to it in the VM it resides in?

  • 772

How can I get ubuntu to use use all the disk space that I allocate in my VM? Is there something I am missing during my install of ubuntu? When I created my VM I designated 250GB of disk space before I installed ubuntu! However, ubuntu only took up have 123G. What can I do during install of ubuntu to take all that I allocate to it in the VM it resides in?
