Expanding Disk Space on Contabo VPS

2 min readUpdated September 25, 2026

This guide applies when you purchase additional storage space for services in the Contabo location.

Note that expansion is only possible within the same storage architecture (migrating from NVMe to NVMe or from SSD to SSD). If you switch, for example, from an NVMe drive to an SSD, a complete disk replacement with data removal is required.

Connect to the virtual server. Then install the required software with the following command:

bash

apt install cloud-utils -y

Retrieve information about the system partition in use. In our example (and typically on all Contabo VPS servers) this is :

bash

mount | grep ' / '

Information about the system partition in use

Now run the following commands to expand the disk:

bash

sudo growpart /dev/sda 3
sudo resize2fs /dev/sda3

In both commands, the number "3" refers to the partition being used. Replace it with your own value if necessary.
