Extending Disk Partitions and File Systems (Windows Server 2008)

Scenarios

After a disk is expanded on the management console, the disk size is enlarged, but the additional space cannot be used directly.

In Windows, you must allocate the additional space to an existing partition or a new partition.

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

Performing the expansion operations with caution. Incorrect operations may lead to data loss or exceptions, so you are advised to back up the disk data using CBR before expansion. For details about using CBR, see Managing EVS Backups.

Prerequisites

• You have expanded the disk capacity and attached the disk to a server on the management console. For details, see Expanding Capacity for an In-use EVS Disk or Expanding Capacity for an Available EVS Disk.
• 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.

System Disk: Add the Additional Space to the Original Volume

In this example, the system disk has 50 GiB originally, and 22 GiB is added on the management console. The following procedure describes how to add this 22 GiB to volume (C:) on the server. After the operation is complete, volume (C:) will have 72 GiB of capacity and can be used as a system volume.

1. On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.

   The Server Manager window is displayed.

2. In the navigation tree, choose Storage > Disk Management.

   The Disk Management window is displayed.

   If you cannot see the additional space, right-click Disk Management and choose Refresh from the shortcut menu.

3. On the Disk Management page, select the disk and volume that you want to extend. The current volume size and unallocated space are displayed.
4. Right-click the target volume and choose Extend Volume.

System Disk: Create a New Volume with the Additional Space

In this example, the system disk has 40 GiB originally, and 60 GiB is added on the management console. The following procedure describes how to use this 60 GiB to create a new volume, for example volume (F:), on the server. After the operation is complete, new volume (F:) has 60 GiB of capacity and can be used as a data volume.

1. On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.

   The Server Manager window is displayed.

2. In the navigation tree, choose Storage > Disk Management.
   The Disk Management window is displayed.

3. If you cannot see the additional space, right-click Disk Management and choose Refresh from the shortcut menu.

   After the refresh, the additional space is displayed in the right area and is unallocated.

Data Disk: Add the Additional Space to the Original Volume

In this example, the data disk has 100 GiB originally, and 50 GiB is added on the management console. The following procedure describes how to add this 50 GiB to volume (D:) on the server. After the operation is complete, volume (D:) has 150 GiB of capacity and can be used as a data volume.

1. On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.

   The Server Manager window is displayed.

2. In the navigation tree, choose Storage > Disk Management.
