Resize Kali Disk

ResizeKaliDisk.txt

I needed to increase my Kali VM's drive space from 7GB to 30GB because I ran out of space.  I use VirtualBox, so here's how I increased the size of the virtual disk.

The virtual disk was in the vmdk format, so I had to clone that and change it to vdi so that I could expand it.  Here's how I did that:
VBoxManage.exe clonehd "C:\Users\maravedi\VirtualBox VMs\Kali\Kali-disk1.vmdk" "C:\Users\maravedi\VirtualBox VMs\Kali-disk1.vdi"
VBoxManage.exe modifyhd "C:\Users\maravedi\VirtualBox VMs\Kali\Kali-disk1.vdi" --resize 30720

Next, I had to expand the root partition within the OS.  I found two resposnes on AskUbuntu that, when combined, helped me solve this problem:

1. Run swapoff /dev/sda5

2. Run sudo fdisk /dev/sda

3. Use p to list the partitions. Make note of the start cylinder of /dev/sda1

4. Use d to delete first the swap partition (2) and then the /dev/sda1 partition. This is very scary but is actually harmless as the data is not written to the disk until you write the changes to the disk.

5. Use n to create a new primary partition. Make sure its start cylinder is exactly the same as the old /dev/sda1 used to have. For the end cylinder agree with the default choice, which is to make the partition to span the whole disk.

6. Use a to toggle the bootable flag on the new /dev/sda1

7. Review your changes, make a deep breath and use w to write the new partition table to disk. You'll get a message telling that the kernel couldn't re-read the partition table because the device is busy, but that's ok.
Reboot with sudo reboot. When the system boots, you'll have a smaller filesystem living inside a larger partition.

8. Run sudo resize2fs /dev/sda1 - this will default to making the filesystem to take all available space on the partition.

Ok 🆗🆗🆗🆗🆗
