This morning, I worked on an Ubuntu Server 14.04 guest who’s disk space has been increased by the VMWare host. LVM was configured on the guest during installation, so that simplified the process of getting the extra space rolled into the original partitioning scheme. Below is a set of instructions that I was able to use on this live server without interruption in service. Your results may vary though. There are GUI tools that you can use for much of this, but I prefer to work in the terminal as the knowledge tends to be more universal. Being able to work without a GUI is also a requirement with many server systems, and in emergency recovery situations as well.
