The disk capacity does not increase after disk resizing in ECS

Last Updated: Dec 30, 2020

Problem description

The disk capacity does not increase after the disk in ECS is resized.

Cause

The resizing operation in the ECS console is only to resize the storage capacity of the cloud disk. It does not resize the file system of the ECS instance. You must also log on to the instance and resize the file system .

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.
