I think it is not possible, you can undo the changes

Defragmentation - Depending on the guest operating system and the file system used on the virtual disk, you might consider defragmenting the disk. This can help optimize the disk's usage of space.

What version are you using. Please backup first before you do sizing of Disk

You can do Inside the VM's operating system, perform a disk cleanup to remove unnecessary files, temporary files, cached data, and other items that can free up space. This step can help reduce the size of the virtual disk.

Apply Modifications: After altering the virtual disk's size, do so. This step could involve validating the modifications or starting the resizing procedure.

Start the virtual machine (VM) after resizing the disk. The filesystem may need some extra time to adapt to the larger disk space before the VM can start.

Resize the filesystem after logging into the virtual machine to make use of the newly allotted space. In order to do this, the correct commands must be used according on the kind of filesystem, such as xfs_growfs for XFS filesystems or resize2fs for ext-based filesystems.

Hi,

There are a few ways to reduce VM disk size on aCloud (HCI). Here are a few options:


  • Delete unused files and folders: One of the easiest ways to reduce the size of a VM disk is to delete any unused files and folders. You can do this by using File Explorer or by using a command-line tool such as rm.

  • Compress files and folders: You can also compress files and folders to reduce their size. This can be done using a compression tool such as WinRAR or 7-Zip.

  • Defragmenting the disk: Defragmenting the disk can help to improve the performance of the VM and can also free up some space. You can defragment the disk using the Windows Disk Defragmenter tool.

  • Use a thin provisioned disk: A thin provisioned disk is a type of disk that only allocates the amount of space that is actually needed. This can help to reduce the size of the VM disk and can also save money.

  • Migrate the VM to a smaller disk: If the VM is using a large disk, you can migrate it to a smaller disk. This can be done using the vSphere Client or by using a command-line tool such as vmotion.

The best way to reduce the size of a VM disk will depend on the specific VM and the amount of space that you need to free up.

Here are some additional things to keep in mind:


  • When you delete files and folders, they are not actually removed from the disk immediately. They are marked as deleted and will be overwritten by new data when the disk needs more space.

  • When you compress files and folders, they are stored in a more efficient format, which can reduce their size. However, compression can slow down the performance of the VM.

  • Defragmenting the disk can help to improve the performance of the VM by organizing the files on the disk in a more efficient way. However, defragmentation can take some time and can also slow down the performance of the VM temporarily.

  • Thin provisioned disks can help to reduce the size of the VM disk and can also save money. However, thin provisioned disks can also be slower than thick provisioned disks.

  • When you migrate a VM to a smaller disk, you will need to make sure that the new disk is large enough to accommodate the VM's operating system and applications.

I hope this helps!
