Last updated: 2022-09-29 17:38:24


    This document describes how to initialize a cloud disk newly mounted to a CVM, create a file system, and write a file named qcloud.txt.


    For more information on cloud disk initialization, see Initialization Scenarios.


    To protect important data, see Usage FAQs before performing any operation on your CBS cloud disks.




    This section uses a CVM instance with Windows Server 2012 R2 DataCenter 64-bit English installed as an example. Note that the steps may vary by operating system version.

    1. Log in to the Windows CVM instance as the admin user. See Logging in to Windows Instance Using RDP (Recommended).
    2. On the desktop, right click in the lower-left corner.
    3. In the pop-up menu, select Disk Management.
    4. (Optional) Right-click the target disk and select Online.
      When the disk status changes to Not Initialized, it has gone online.
    5. (Optional) Right-click an online disk and select Initialize Disk. In the pop-up window, select MBR (Master Boot Record) and click OK.
      • The master boot record (MBR) format supports a disk of up to 2 TB, while GUID partition table (GPT) supports a disk of up to 18 EB. If you need a larger capacity than 2 TB, adopt GPT.
      • If the partition format is changed for a disk in use, the original disk data will be cleared. Therefore, select the disk partition format with caution when initializing the disk.
    6. Right-click the target disk and select New Simple Volume. In the pop-up window, click Next.
    7. Enter the size of the simple volume and click Next.
    8. Select the drive letter or path and click Next. Here, the drive letter E is used as an example.
    9. Select the file system, perform a quick format, and then click Next.
    10. Click Complete.
      The disk status becomes Formatting. Wait for the completion of initialization. When the volume status becomes Healthy, the disk initialization is successful. You can then view the newly formatted data disk in the PC interface.
    11. Go to the newly partitioned data disk, create the qcloud.txt file, enter the content, and select File > Save.
