Expand the centos hard disk size in virtualbox

1. Clone an object I created centos 6.3 During the previous installation, but I didn't have enough space to reinstall centos. I thought about using the resize command because I had to configure many things, however, when running D: \ Program Files \ oracle \ virtualbox> vboxmanage.exe modifyhd "D: \ centos 6.3.vdi" -- resize 12288 in Win8, an error is always reported. The error is as follows: vboxmanage.exe: Error: resize hard disk operation for this format is not impleme nted yet! No way. You can see it on the Internet. First, create an empty and large VDI on the virtual machine, and then use the clonehd command to clone it. Run the following command:
After that, mount the new VDI image to virtualbox and start the new VDI file, Ii. Extended partitions Run DF-h to check whether the root directory is the same as the original one. Use LVM to expand the partition. LVM (logic volume manager) logical management volume

For more information about the extension method, see "extend. Very convenient. This is the partition before I expand

This is the partition I extended after gparted-live-0.16.1-1-amd64.iso
