Is it possible to create dynamically growing VMDK files on ESX?
Answer: ESX by design doesn’t provide dynamically growing disks, as it would poorly effect the performance in high-performance ESX environment. If you need to pre-allocate more space, one option is to use console to create a disk of pre-allocated size with “vmkfstools” command. To create a new 10G thin disk in current directory, type: Vmkfstools –c 10G –a lsilogic –d thin ./thindisk.vmdk
