Performing Post-Expansion Operations for a Windows EVS Disk

Scenarios

In a Windows OS, after the capacity expansion succeeded, you need to add the additional space to the disk.

This topic uses Windows Server 2008 R2 Enterprise as the sample OS to describe the expansion methods:
  • System disk: Add the additional space to Disk (C:).
  • Data disk: If Disk (D:) exists, add the additional space to Disk (D:).

    If you want to create Disk (E:), expanding the disk is not the right choice. You need to create a new disk, attach it to server, and initialize it for use.

The method for allocating the additional space varies depending on the server OS. This document is used for reference only. For the detailed operations and differences, see the corresponding OS documents.

Performing the expansion operations with caution. Misoperation may lead to data loss or exceptions. Therefore, you are advised to back up the disk data using backups or snapshots before expansion. For details about backups and snapshots, see Managing EVS Backup and Creating a Snapshot, respectively.

Prerequisites

  • You have logged in to the server.
    • For how to log in to an ECS, see the Elastic Cloud Server User Guide.
    • For how to log in to a BMS, see the Bare Metal Server User Guide.
  • You have attached the EVS disk to the server, and the additional space has not been allocated.
