How to expand disk size of a VM without data loss?

Hello everyone, can anybody tell me step by step how to expand disk size of VM with RHEL 5 OS in Sangfor HCI without data loss?

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.

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.

You can expand it thru the VMware client itself

You can set it to the built-in wizard or in the virtual machine settings

Thin provisioning is required. Thin provisioning, also known as virtual provisioning or thin storage, is a method of on-demand storage allocation based on user requirements in storage area networks (SAN), centralized storage disks, and storage virtualization systems.

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