Create new partition with fdisk

Question

I have Ubuntu 14.04.2 LTS (32-bit) running in VMware Workstation 10.0.3 build-1895310. I have just modified the Virtual Machine Settings, expanding the Hard Disk from 20 GB to 30 GB. So I would like to create a new partition with these extra 10 GB I just added.

When trying to create a new partition using fdisk /dev/sda and n as Command, I have to specify the size of this new partition. And I tried the following values:

Last cylinder, +cylinders or +size{K,M,G} (2612-3916, default 3916): `10G`
Value out of range.
Last cylinder, +cylinders or +size{K,M,G} (2612-3916, default 3916): `9G`
Value out of range.
Last cylinder, +cylinders or +size{K,M,G} (2612-3916, default 3916): `1M`
Value out of range.

When asked what type of partition I would like to create I tried both options, e (extended) and p (primary), but with no luck. Since not even the 1M value ain't working.. there must be something I'm missing or doing wrong.. What needs to be done to make it work?

fdisk /dev/sda returns this:

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

Command (m for help): **p**

Disk /dev/sda: 32.2 GB, 32212254720 bytes

Partition 1 does not end on cylinder boundary.
/dev/sda2              64        2611    20458496   8e  Linux LVM

Also, df -h returns:

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_box0-lv_root
                       18G  4.4G   12G  27% /
tmpfs                 503M   76K  503M   1% /dev/shm
/dev/sda1             477M   65M  387M  15% /boot

Solution

You have to use a + sign when specifying the size.

So for 10 Gb

    +10G

You have to use a + "+10G"

@bodhi.zazen Oh. You're right. They also did that in the tutorial, but I missed it. You can change you response from comment into an answer. Many, many thanks.
