How to change VMDK disk format from Thin and Thick Provision Lazy Zeroed to Thick Provision Eager Zeroed

一, Use storage vMotion to change the disk format

二, Use command to change the disk format

If the VMDK virtual disk is of type Thin, convert the disk to Eager Zeroed Thick using the vmkfstools --inflatedisk command.

      For example:

      vmkfstools --inflatedisk /vmfs/volumes/DatastoreName/VMName/VMName.vmdk

      Note: The inflate command reports the percentage of completion.

If the VMDK virtual disk is of type Thick, convert the disk to Eager Zeroed Thick using the vmkfstools --eagerzero command.

      For example:

      vmkfstools --eagerzero /vmfs/volumes/DatastoreName/VMName/VMName.vmdk

      Note: The eager zero command reports the percentage of completion.

How to extend vmdk disk

一, extend vmdk disk (Thin or Thick provision lazy zeroed)

# vmkfstools -X [新的大小] [目的vmdk文件]

二, If you need to extend the VMDK and want the VMDK to be EagerZeroedThick, run this command:
For example, to extend the size of the virtual disk to 60 GB:

# vmkfstools -X 60G -d eagerzeroedthick /vmfs/volumes/Datastore_name/virtual_Machine_folder/virtualmachinedisk.vmdk

Notes:
In the preceding vmkfstools -X example, 60 GB is the size that you wantthe disk file to be, is not the size by which you want to extend the disk file.

If you extend the disk by using UI, you have no control over all the options toextend the disk. As a result, the EagerZeroedThick VMDK automatically becomesLazyZeroedThick.
