I have created new instance with Centos 6.4 with 20 GB Disk Space but when i logging to the VPS and Execute df -h the space shown as the following 

Filesystem            Size  Used Avail Use% Mounted on
/dev/vda1             984M  706M  229M  76% /
none                 1012M     0 1012M   0% /dev/shm

and the output of fdisk -l

Disk /dev/vda: 21.5 GB, 21474836480 bytes
4 heads, 32 sectors/track, 327680 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000a5c87

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1              17       16401     1048640   83  Linux

You need to resize partition, then grow filesystem:

  1. Take backup

  2. fdisk /dev/vda -> d -> 1 -> n -> p -> 1 -> 17 -> [enter]

  3. -> p

    ensure that partition is marked with asterisk (*) to be bootable, if not:

    a -> 1

    when done -> w

  4. resize2fs /dev/vda1

    (online process, wait!)

  5. reboot

Note: You are missing swap partition, you can use +xxxxM instead if [enter] to leave some space for swap partition.

    this is how it is. You need to configure parameters during installation or you need other image. – GioMac Sep 07 '13 at 12:16
