- <para>&PRODUCT; does not provide the ability to resize root disks or data disks; the disk size is fixed based on the template used to create the VM. However, the tool <ulink url="http://vmtoolkit.com/files/folders/converters/entry87.aspx/"> VHD Resizer</ulink>), while not officially supported by Cloud.com or Citrix, might provide a workaround. To increase disk size with VHD Resizer:</para>

+ <title>Resizing Volumes</title>
+ <para>&PRODUCT; provides the ability to resize data disks; &PRODUCT; controls volume size by using
+ disk offerings. This provides &PRODUCT; administrators with the flexibility to choose how much
+ space they want to make available to the end users. Volumes within the disk offerings with the
+ same storage tag can be resized. For example, if you only want to offer 10, 50, and 100 GB
+ offerings, the allowed resize should stay within those limits. That implies if you define a 10
+ GB, a 50 GB and a 100 GB disk offerings, a user can upgrade from 10 GB to 50 GB, or 50 GB to 100
+ GB. If you create a custom-sized disk offering, then you have the option to resize the volume by
+ specifying a new, larger size. </para>
+ <para>Additionally, using the resizeVolume API, a data volume can be moved from a static disk
+ offering to a custom disk offering with the size specified. This functionality allows those who
+ might be billing by certain volume sizes or disk offerings to stick to that model, while
+ providing the flexibility to migrate to whatever custom size necessary. </para>
+ <para>This feature is supported on KVM, XenServer, and VMware hosts. However, shrinking volumes is
+ not supported on VMware hosts.</para>
+ <para>Before you try to resize a volume, consider the following:</para>
+ <itemizedlist>
+ <listitem>
+ <para>The VMs associated with the volume are stopped.</para>
+ </listitem>
+ <listitem>
+ <para>The data disks associated with the volume are removed.</para>
+ </listitem>
+ <listitem>
+ <para>When a volume is shrunk, the disk associated with it is simply truncated, and doing so
+ would put its content at risk of data loss. Therefore, resize any partitions or file systems
+ before you shrink a data disk so that all the data is moved off from that disk.</para>
