• VMKFSTOOLS WINDOWS 10 MANUAL

The UI may be different in your environment. Now you can create a new VM with the generated VMDK in the datastore. "Windows-10-64-Enterprise-disk1.vmdk" and "Windows-10-64-Enterprise-disk1-flat.vmdk" are the new files generated by vmkfstools command. Now you should have the following files in the datastore: 1 SSH into your ESXi host, then: vmk fstools -i CentOS7-1/CentOS7-10.vmdk CentOS7-2/CentOS7-2.vmdk -d thin Next, create a new VM as normal, but on the Customize Settings dialog, press the X on the right to delete the disk created by the new VM wizard: Next, press ‘Add new disk’, select ‘Existing hard disk’, then point to the copy of the. vmkfstools -i Windows-10-64-Enterprise-disk1.vmdkĭestination disk format: VMFS zeroedthickĬloning disk ''. Let's rename the uploaded VMDK and do the conversion. There is a command vmkfstools to convert Workstation and Fusion VMDK into ESXi's format. The VMDK format between ESXi and VMware Workstation / Fusion is different, so the uploaded file can't be consumed by ESXi directly. When the export finishes, you can use scp to upload the VMDK file to ESXi datastore. The recommendation is choosing separate files, since only VMDK file is needed in later steps. The VMKFSTOOLS method is safer, just connect the cloned disk to the VM, that way if it doesn’t boot you can go back to the original VMDK file and descriptor (that you copied before modifying, remember?) **This information is provided “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.A VM can be export as a single OVA file, or two separate files (OVF file + VMDK file). CP your VMDK file first in case you mess up with VI! Also, the ‘cold migrate’ method shown above moves the VMDK file and deletes the original, so if you mis-calcuated and corrupted your Guest OS then you are out of luck. Don’t forget to multiply by 1024 to get from GB to MB to KB to B then divide by 512 to get the value. I also rounded the partition size up by 0.1GB to allow for calculation variances, e.g., 20GB = 20.1GB. This method works like a champ! Just be double-triple sure to resize the Guest OS partition smaller before starting this. SVMotion would be the a favourable option for those that do not want to incur downtime for their VM.

This will reduce disk space required for this operation and it will be a whole lot cleaner than a manual clone with vmkfstools and then a remove of the original. Change your values and then migrate the disks via VI Client/VC to a different datastore. This would be less cumbersome than trying to play around with another disk at the command line during a simple shrink process. This technique will also work if you try to cold migrate the VM or Storage VMotion it.

You will discover that the cloned disk now reflects the new size of 12.5G: * For this example I will to shrink the disk to 12.5GĪfter making this change you can use ‘vmkfstools -i’ to clone this disk: If you want to shrink (or increase) the size of your vmdk file, alter this value in the descriptor file to reflect your new desired size*. The value between ‘RW’ and ‘VMFS’ is the size of disk when divided by 512: If you have ever taken a look at the descriptor file for a vmdk file, you will the “Extent description” section: I do not and will not take responsibility for your corrupted vmdk’s as a result of following this process, whether correctly or incorrectly ** For those people I just mentioned, I have a treat for you: The reason for this probably stems from those few customers that were not familiar with using the command properly and ended up cutting off too much of the disk and corrupted their Guest OS file system as a result.Įver since the option was removed there have been more experienced users wanting the option to be added back to vmkfstools as they are aware of the risks and want that ability again. While it is a somewhat known fact that you used to be able to shrink disks using vmkfstools -X in ESX 2.x, the option was removed as of ESX 3.0.
