Scenarios

This document describes the operation methods and related precautions of the system disk scale-out.

Limitation Factor

  1. The disk configuration can be adjusted only when the system disk is cloud storage.
  2. To prevent data loss, the system disk only supports scale-out but not support scale-in.

Operation Steps

  1. Log in to the CVM Console.
  2. In the cloud host list, select the instance for which you want to adjust the system disk and click More > CVM Configuration > Adjust Disk.
  3. In the pop-up Adjust Disk window, select a disk and click Next.
  4. Scale out according to actual needs and click Next.
  5. Read the page prompts carefully, then click Start adjusting.
  6. On the CVM list page, the status column will display Expansion Instance Disk. When this field disappears, the disk adjustment is complete.
