Expanding the disk size of a virtual machine (VM) can be done without data loss by following these general steps:
  • Backup your virtual machine. This step is essential to ensure that your data is safe in case anything goes wrong during the expansion process.
  • Shut down the virtual machine. Expanding the disk size requires the VM to be turned off.
  • Expand the virtual disk. Depending on the virtualization platform, you can either increase the disk size through the hypervisor or by editing the virtual machine configuration file directly.
  • Power on the virtual machine. After the disk size has been expanded, turn on the virtual machine.
  • Extend the partition. Once the virtual machine has booted up, you need to extend the partition to use the additional disk space. This process varies depending on the operating system you are using. For example, on Windows, you can use the Disk Management tool to extend the partition. On Linux, you can use the "fdisk" or "parted" command-line tools.

By following these steps, you can safely expand the disk size of your virtual machine without losing any data. However, it is always a good practice to have a backup of your data before making any changes to your virtual machine.

Follow the following procedure:

1. Increase virtual disk with command line. Type vmware-vdiskmanager -x 100Gb vm.vmdk and press Enter to rezise the disk.

2. Increase virtual disk with VMware Workstation client. In VMware Workstation, select the target virtual machine > select Edit Virtual Machine Settings > click Hrad Disk > click Utilities > select Expand > enter the target virtual disk size > click Expand.

The built-in wizard or the virtual machine settings can be used to configure it.

By following these general steps, you can increase a virtual machine's (VM) disk size without losing any data:
Make a virtual machine backup. This step is crucial to make sure your data is secure in case the expansion process goes wrong.
Put the virtual machine to sleep. The VM must be shut down in order to increase the disk size.
Boost the virtual disk's size. You can either increase the disk size using the hypervisor or by directly editing the virtual machine configuration file, depending on the virtualization platform.
the virtual machine is turned on. Start the virtual machine after expanding the disk size.
Stretch the partition out. To use the additional space after the virtual machine has started, you must expand the partition.

This calls for thin provisioning. In storage area networks (SAN), centralized storage disks, and storage virtualization systems, thin provisioning, also referred to as virtual provisioning or thin storage, is a technique for allocating storage on-demand based on user requirements.
