You present 15 GB is rather small and may soon become too small when using it. This will enable you to be generous with space. So when creating a 100 GB dynamically allocated drive it may only use 8 GB of physical space or less. bash-4.1 fdisk -u /dev/sdc Type p at the prompt to list the partitions on the disk. Run the fdisk -u command to open the partition table for the disk in sector mode. You need to use a tool such as fdisk, gdisk, or gparted (or other GUI equivalents) to create a partition from the extra space. Use the fdisk command to extend the partition. On the guest VM, the kernel will recognize the increase in disk size, but its not usable yet. Update the size of the disk to the desired value. The current disk space can be viewed through the command line VBoxManage.exe list. The actual physical size will be much lower. VirtualBox keeps VM disks as individual files on the host system. So I decided to adjust the size of the ubuntu virtual machine disk to 30G. This means they will grow on demand up to the maximum size you gave it. Now delete this partition by typing d and then type w to save these. Remember Start value (2048 in this example). You can even create a new virtual drive, attach it to your existing virtual machine, and copy your data over.Ī new hard drive should be made a dynamically allocated disk (this is the default for new drives in Virtual Box). Now run fdisk command with our test disk name as an argument and then type p to print the list: The last line contains important info about the current partition size and its bounds: Start and End. Because you then would already have a backup it would be much much faster to just create a new virtual hard drive where you can restore your backup and keep going. How can I expand a partition into non adjacent free space using GParted?įor your layout it means you would have to remove your swap partition ( sda2 and sda5) before you can join the adjacent space.Īll of these procedures take considerable time and will put you data at risk. Open virtual machine settings and click Storage on the left pane.After that you will have to partition the drive with gparted from a live session and maybe join partitions. It is possible to grow the hard drive in Virtual Box, as you had already found out.
