When you are running Ubuntu, it is certain that the root partition /, which is /dev/sda1 on your computer, is mounted thus the command will give a failure. The manual for zerofree indicates that if you want to run this on a filesystem, then that filesystem must be either mounted readonly, or unmounted. It should be available in your Linux distribution’s software repositories.įor example, you can install it on Ubuntu by running the following command at the terminal inside your virtual machine: To do this, you’ll first need to install the zerofree utility inside the virtual machine. We’ll use Ubuntu as the example here, but the process will be similar on other Linux distributions. If you have Linux installed in as GUEST in the virtual machine use built-in commands to zero the free space on the drive. Step Two: Write Zeros to the Disk in The Virtual Machine If you have a fixed size disk you want to shrink, you can first convert it to a dynamic disk. This process only works for dynamic disks, which can grow and shrink in size. Step One: Ensure You’re Using a Dynamic Disk But you can manually shrink a dynamic disk using a hidden command. However, if you delete data from the virtual machine later, you’ll notice that the disk doesn’t automatically shrink. NOTE: In this guide we are using a Linux HOST and a Linux GUEST.īy default, VirtualBox creates dynamic disks that grow over time as you add data. How to Shrink a VirtualBox Virtual Machine
