How can I get Ubuntu to recognize the size of the disk it's on?

  • 772

I was coming dangerously close to filling up a virtualbox disk(.vdi) with Ubuntu on it.

So I enlarged the disk

    VBoxManage modifyhd YOUR_HARD_DISK.vdi --resize SIZE_IN_MB

I went from a 6GB disk to a 12GB disk.

Virtualbox recognizes the new disk size. However booting into the Ubuntu guest does not.

How can I tell Ubuntu to take a look at the disk size?

Ubuntu 11.04 64bit - Host

Ubuntu 10.04 32bit - Guest

    The disk might be bigger but the partition on that disk is still the same.

    You want to boot the virtual machine into a LiveCD environment and resize the partition:

    • Download the iso
    • Mount the ISO as the CD drive in the VM settings and boot the VM
    • Press Del or F2 (whatever you need to change the boot order) and make it boot to CD first
    • Get to the LiveCD environment.
    • Use gparted (aka Partition editor) to resize your partition (select the partition, right click, resize, drag the slider up so it fills the disk)
