Extending Disk Partitions and File Systems (Windows Server 2008)¶
Scenarios¶
After a disk has been 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.
This section uses Windows Server 2008 R2 Enterprise 64bit as the sample OS to describe the expansion methods:
For a system disk:
If volume (C:) already exists, you can add the additional space to volume (C:) and use it as a system volume. For details, see System Disk: Add Additional Space to Volume (C:).
If volume (C:) already exists, you can create a new volume such as volume (F:) with the additional space and use the new volume as a data volume. For details, see System Disk: Create New Volume (F:) with Additional Space.
For a data disk:
If volume (D:) already exists, you can add the additional space to volume (D:) and use it as a data volume. For details, see Data Disk: Add Additional Space to Volume (D:).
If volume (D:) already exists, you can create a new volume such as volume (E:) with the additional space and use the new volume as a data volume. For details, see Data Disk: Create New Volume (E:) with Additional Space.
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.
Important
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 or snapshots before expansion. For details about using CBR, see Managing EVS Backups. For details about using snapshots, see Creating a Snapshot.
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.
System Disk: Add Additional Space to Volume (C:)¶
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.
On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.
The Server Manager window is displayed.
In the navigation tree, choose Storage > Disk Management.
The Disk Management window is displayed.

Note
If you cannot view the additional space, right-click Disk Management and choose Refresh from the shortcut menu.
On the Disk Management page, select the disk and volume that you want to extend. The current volume size and unallocated space are displayed.
Right-click the target volume and choose Extend Volume.

System Disk: Create New Volume (F:) with 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.
On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.
The Server Manager window is displayed.
In the navigation tree, choose Storage > Disk Management.
The Disk Management window is displayed.

Data Disk: Add Additional Space to Volume (D:)¶
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.
On the desktop of the server, right-click Computer and choose Manage from the shortcut menu.
The Server Manager window is displayed.
In the navigation tree, choose Storage > Disk Management.
The Disk Management window is displayed.
