Cloud Disk Expansion Scenarios

    Expanding cloud system disks

    If the cloud disk works as a system disk, you can expand it using the following two methods.

    Expanding cloud data disks

    If the cloud disk is a data disk, you can expand it using the following three methods.

    Based on the mounting status of CBS data disks, you can expand their capacity by different methods.

    • If the current CBS data disk can be unmounted, you can expand its capacity in the CBS console or via the ResizeDisk API.
    • If the current CBS data disk cannot be unmounted, you can expand its capacity in the CVM console or via the ResizeDisk API.

    Note:

    If the maximum capacity of the cloud disk cannot meet your business needs, please try building up RAID groups or building LVM logical volumes with multiple elastic cloud disks.

    Once the data disk capacity is expanded, you must perform the following operations for the instance to recognize and use the data disk:

    Before Expansion After Expansion Subsequent Operations
    File system not created Disk capacity < 2 TB/td> Initializing cloud disks (< 2 TB)
    Disk capacity ≥ 2 TB Initializing cloud disks (≥ 2 TB)
    File system created Disk capacity < 2 TB/td>
    Disk capacity ≥ 2 TB
