Initializing Cloud Disks (<2 TB)

Last updated: 2022-09-30 14:34:22


    This document describes how to initialize a cloud disk with a capacity less than 2 TB. For more cases, see Initialization Scenarios.


    You have attached the cloud disk to your CVM.


    • Read FAQs about cloud disk usage before working with cloud disks.
    • Formatting a data disk will erase all data. Make sure that the disk does not contain data, or important data has been backed up.
    • To prevent service exceptions, ensure that the CVM has stopped providing external services before formatting.



    This example uses a Lighthouse instance using Windows Server 2012 R2 operating system. Note that the steps may vary according to the operating system version.

    1. Log in to the Windows CVM instance.
    2. On the desktop, right-click in the lower-left corner.
    3. Select Disk Management in the pop-up menu.

      If the newly added disk is in offline status, execute Step 4 before Step 5 to perform initialization. Otherwise, you can directly execute Step 5.

    4. Disks are listed on the right-side pane. Right-click disk 1 area, and select Online to bring it online. The status of disk 1 changes from Offline to Not Initialized.
    5. Right-click disk 1 area and select Initialize Disk in the menu.
    6. In the Initialize Disk pop-up window, the disk to be initialized is displayed. Select MBR (Master Boot Record) or GPT (GUID Partition Table) and click OK.

      If the disk partition format is changed after the disk is put into use, the original data on the disk will be erased. Select an appropriate partition format based on actual needs.

    7. Right-click the free space of the disk, and select New Simple Volume.
    8. In the New Simple Volume Wizard pop-up window, click Next.
    9. Specify the volume size as needed, which is the maximum value by default. Click Next.
    10. Assign a drive letter and click Next.
    11. Select Format this volume with the following settings, configure parameters as needed, format the partition, and click Next to complete the partition creation.
    12. Click Complete to complete the wizard. Wait for the completion of initialization. When the volume status becomes Healthy, the disk initialization is successful.
      After the initialization is complete, enter the PC interface to view the new disk.
