Reducing disk size on VM to free up datastore?

hi guys

I've got a slight problem. One of our servers has somehow been given way too much space and now we've run out of space on our datastore which in effect is causing the VM to go down?

I've attached photos of examples of some disk we have and would like reduce/shrink if at all possible (although I'm sure with thin provisioned disks you can't just shrink them). For example, one of the disks added has been given 1TB of space but only 100gb has been used. They're both thin provisioned.

We're running Esxi 4.1 at the moment. Is there any way to reduce the disk sizes at all without losing data?

Many thanks
Yashy

Yes, there is a method of reducing space without losing data, it looks like you allocated a 1.1TB thin disk, and over-subscribbed your datastore.

Options

1. VMware Converter and create a V2V

3. Create a new disk of the correct size and copy the data, using xcopy, robocopy, ghost, clonezilla, drive snapshot.

Copy the 100 GB of data on it to your Volume E.  Delete the drive in vsphere and only make it 200 GB this time.  Make it dynamic in Windows also.  And if you need more space, wallah, expand it...
