We’re in the middle of a VMware migration from 3.5 to 4. Some of the older VMs have small C drives, and since Microsoft loves to release tons of patches, they’re running out of space.
In the past you could shut the VM off, attach the OS drive as an extra HD to another VM, increase the space and then use diskpart to extend it. With VM Hardware v.7, it’s much easier!
Grab the ExtPart tool from Dell here.
1) Edit the VM’s settings to increase the disk size
2) Copy ExtPart to the VM and double-click to extract. Default path is C:\Dell\ExtPart\
3) Check the Partitions before:
4) From a command-prompt, change to the ExtPart directory
5) Run extpart.exe
6) Enter in the disk you want to extend in lower-case, i.e., c:
7) Specify in MB of the amount of space you want to ADD, not the final total
Check partitions after
9) That’s all!
*note: your partition in “Disk Management” will look funny until you quit and re-open Disk Managment:
{ 3 trackbacks }
{ 4 comments… read them below or add one }
First of all, thank you for the step by step instruction they were very helpful. Sometimes is hard to remember small details that are very useful, I just want to add that in order to extend the VM disk size it’s necessary to have the virtual hdd in dynamic type.
Thanks,
Thank you for this tip, worked for me without a hitch: vSphere 4.1.0 260247 for guest running Windows 2003 R2 32-bit.
Also, to get the exact size to increase the disk, its quick to just get properties on the new volume from within disk manager, select the Volume tab. This lists the available size in mb.
Thanks for the Info, It works for me.
Thanks. Looking a while for this !!
