Steve Jones shows how to add disk space to a Linux partition:
While working with some SQL Server 2017 tests, I ran out of disk space. I tend to size my VMs around 40GB, and that works for some things, but I’ll run out of space.
I needed to expand the VMWare disk. That doesn’t mean Linux sees the space directly, and I had to figure out how to make the partition bigger. I could have added another disk, but I wanted to work through this process. I learned I needed to have an inactive partition, so I download gparted on a live cd and booted to that.
Steve uses the GUI approach; in the comments, David Klee links to his CLI approach.
