Problem description

For a Windows-based ECS instance, the resized disk space is displayed, but the original space in the partitions is not displayed.

Cause

The NTFS file system is not recognized by the extended service. You need to manually resize it.

Solution

Alibaba Cloud reminds you that:

Before you perform operations that may cause risks, such as modifying instance configurations or data, we recommend that you check the disaster recovery and fault tolerance capabilities of the instances to ensure data security.

You can modify the configurations and data of instances including but not limited to Elastic Compute Service (ECS) and Relational Database Service (RDS) instances. Before the modification, we recommend that you create snapshots or enable RDS log backup.

If you have authorized or submitted sensitive information such as the logon account and password in the Alibaba Cloud Management Console, we recommend that you modify such information in a timely manner.

Remotely connect to the Windows ECS instance.
Click start, cmd, click Enter, and open the command-line tool.
Run the following commands in sequence to perform a manual scale-out:
```
diskpart
list volume
select volume [$Number]
extend filesystem
```
Note: [$Number] indicates the Number of volumes.
