Convert thick disks to thin provisioning | ESX

Got Space? I don’t

Seeing how it’s not possible to convert a VMWare Guest VM’s from ‘thick’ to ‘thin’. I will provide some simple info on how to clone the disk into a ‘thin’ disk. Once completed the original ‘thick’ disk can be deleted

# remote into your ESX Server
# service console can be used also
# change into your machine directory and type
vmkfstools -i <*thickDiskname.vmdk> -d thin <thintDiskname.vmdk>
