I have two 10.04 servers running on a VMware ESXi 4.0. Unfortunately, I gave one of the servers to much space, and the other to little. So, I resized the harddrive in my hypervisor - giving more space to virtual server 2. Unfortunately, when logging in to server 2, it still believes that it has just 10 GB of hardrive space. How can I make the server use all the new available space I have dedicated to it from the hypervisor ?
