Resize virtual box hard drive
Raw
resize_virtualbox.md

A mix of these tutorials:

  • create a new (bigger) virtual hd
  • use a gparted iso, create a virtual machine and attach the iso, the old (smaller) hd and the new hd to the machine
  • once started, identify the two hard drives and launch: 
    dd -if=/dev/sda of=/dev/sdb

be careful because if you invert if and of you will delete your original hd. This will take a lot of time to copy everything from one hard drive to the other.

  • At this point you will have an hd with all of the original partitions, and a lot of unallocated space. Just resizing the original partitions in gparted won't work.. some trickier adding and merging is needed:

First of all add an LVM partition using gparted, then follow these instruction from Increasing the logical volume: https://www.rootusers.com/how-to-increase-the-size-of-a-linux-lvm-by-expanding-the-virtual-machine-disk/
