How to extend the boot system volume of a Vmware virtual machine
April 1st, 2010
I had a server running Windows 2003 on Vmware Esx 4 that was running out of disk space. It is a pretty simple process to extend the disk space but it took some hunting around to find it.
- Shut down the virtual machine.
- Edit the disk you want to expand using the Vmware client, edit the disk and increase the size.
- Boot the virtual machines into Windows, go to disk management and verify the unallocated disk space is available.
- You won’t be able to extend the volume if its the boot volume so you’ll need a partition manager to extend the disk.
- Download the GParted open source partition manager Live CD, mount the iso and boot the virtual machine from it, then extend the disk and boot into Windows.
I believe in Windows 2008 you can do all this from within Windows but haven’t had to test that yet.
