Welcome to the blog of mechanised.com

This blog is mainly a technical repository of information on Virtualisation tools and management for our hosting service.

Also for HP's Bladesystem that we use at both our datacentres.

Other articles are also included on .Net development and MS SQL Server as well as other interesting things we come across.

Converting VMDK files to thin provisioned

To convert VMDK files in ESX/ESXi you'll need to login via SSH and run this command in the datastore.

vmkfstools -i fatdisk.vmdk -d thin thindisk.vmdk

Don't forget to either rename the existing disk (and edit meta data) or change your VMX file afterwards to point to the new disk.

Does take a considerable time though!
