Initializing Cloud Disks (≥2 TB)

Last updated: 2021-11-26 14:35:45


    This document describes how to initialize a cloud disk with a capacity greater than or equal to 2 TB. For more cases, see Initialization Scenarios.
    MBR supports disk with a maximum capacity of 2 TB. When you partition disk with a capacity greater than 2 TB, we recommend that you use the GPT partition format. When GPT is used on Linux operating system, fdisk can no longer be used and the parted tool must be used.


    You have attached the cloud disk to your CVM.


    • To protect important data, please see Usage FAQs before operating on your CBS 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 document uses a CVM with Windows Server 2012 installed as an example. Note that the steps may vary according to the operating system version.

    1. Log in to the Windows CVM instance.
    2. On the desktop, click to enter the Server Manager page.
    3. In the left navigation tree, click File and Storage Services.
    4. In the left navigation tree, select Volumes > Disks.

    If the newly added disk is in offline status, execute Step 5 before Step 6 to perform initialization. Otherwise, you can directly execute Step 6.

    1. Disks are listed on the right-side pane. Right click the row where 1 is located, and select Online to bring it online. Then its status becomes Online.

    2. Right click the row where 1 is located, and select Initialize in the menu.

    3. Follow instructions on the interface, and click Yes.

    4. After initialization, the partition of 1 changes from Unknown to GPT. Right click the row where 1 is located and select New Simple Volume in the menu.

    5. In the pop-up New Volume Wizard dialog box, follow instructions on the interface and click Next.

    6. Select the server and disk, and click Next.

    7. Specify the volume size as needed, which is the maximum value by default. Click Next.

    8. Assign a drive letter, and click Next.

    9. Configure parameters as needed, format the partition, and click Next to complete the partition creation.

    10. Confirm the information and click Create.

    11. Wait for the completion of the volume creation, and then click Finish.
      After the initialization is complete, enter the My Computer interface to view the new disk.
