How to decrease the size of your Virtaul Disk?

 

Hello All

 

 

I have a question about decreasing the size of an existing VM's hard disk VMFS.

 

 

I converted a physical server to VM by using VMware Converter.

I have re-sized the partition using a partitioning tool but unable to decrease the size of the physical disk under Intrastructure Client.

 

 

While i know how to increase the disk, im unable to decrease the size.

 

 

Can anyone assist.

 

 

Im using Intrastructure client and not Virtual Center.

VMware ESX 3.5 Server.

 

 

Regards

This is a great article that should help you out with your issue: http://communities.vmware.com/click.jspa?searchID=2240814&objectType=2&objectID=450465

 

 

It talks about expanding the disk but the same process can be used to shrink the disk as well.  And this process also works on your BOOT disk in your VM!  I use it all the time.  Good luck!

Yes i would like to add a point here.... That is the strength of "MIGRATIONS", even though i have not used vmware convertor... i used a similiar tool i.e. HP Server Migration Pack... in which you can actually resize/shrink the partitions if you want to.... and the destination machine would have those changes present in it ...

Hello,

 

 

We are getting ready to convert a DC/Exchange 2003 server to a VM.  Any advice before we start?

 

 

 

 

 

Thanks,

 

 

Wally

We've been able to do this on Windows VMs by:

 

  1. Adding a new VMDK of the desired size

  2. Boot the VM off our BartPE boot ISO

  3. Use Ghost32 off the BartPE to image the old (large) disk to the new (small) disk

  4. Restart the VM

  5. Change the drive letters as required

  6. After verifying proper operation, shut down the VM and remove the old (large) disk
