Three Ways for Extending a VM’s Disk

Gparted_1_SmallMost new virtual servers are provisioned from templates that have 12 to 20 GB “C” disk so what do you do when you run out of space?

Here are three methods that might work for you to increase the size of your virtual server’s disk.

1. Use VMconverter from VMware to clone the VM and change the size of the drive.

2. Build a Windows 2003 VM that can be used to mount the “C” drive VMDK of the target VM as an additional drive, then use the VM setting on the tool to increase the disk size.

3. Once the disk size is increased use the Windows “diskpart” command to grow the partition. Don’t forget to unmount the disk from the tool.

Then there’s a sweet free tool called GParted that boasts the following features:



GParted also has a nice GUI as seen in the upper right and best of all, it’s free.

Gnome Partition Editor

GParted is the Gnome Partition Editor application. Before attempting to use it, here is some basic background information.

A hard disk is usually subdivided into one or more partitions. These partitions are normally not re-sizable (making one smaller and the adjacent one larger). The purpose of GParted is to allow the individual to take a hard disk and change the partition organization therein while preserving the partition contents.

GParted is an industrial-strength package for creating, destroying, resizing, moving, checking, and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another (disk imaging). See Features, before using it.

GParted uses GNU libparted to detect and manipulate devices and partition tables.

Several (optional) file system tools provide support for file systems not included in libparted.
These optional packages will be detected at runtime and do not require a rebuild of GParted.

GParted is written in C++ and uses gtkmm for its Graphical User Interface (GUI). The general approach is to keep the Graphical User Interface as simple as possible. Every attempt was made to conform to the GNOME Human Interface Guidelines.
