Last Updated: Tue, Nov 17, 2020

Introduction

This guide explains how to add, grow, and shrink partitions of a Vultr cloud server with GParted, a graphical partition editor. If you have upgraded your cloud server with a larger disk or need to expand a partition while preserving data, follow these steps. A cloud server instance is sometimes called a Virtual Private Server or VPS.

This guide temporarily boots your cloud server with the SystemRescueCD ISO to run GParted, which works with a majority of operating systems.

1. Make a Backup

NOTE: These operations make destructive changes to the cloud server's file system. You can lose data if you make a mistake following these directions. Make a snapshot of the server before performing any of these steps. If your data is critical, please test the snapshot before proceeding. Deploy a new test instance with the snapshot, then verify the test instance boots and has the correct data.

2. Boot SystemRescueCD

  1. Navigate to your cloud server information page.
  2. Click the Settings tab.
  3. Click Custom ISO on the left menu.
  4. Select SystemRescueCD - 6.1.8 from the ISO Library drop-down.
  5. Click Attach ISO and Reboot.

Attach ISO

3. Launch GParted

  1. Open the web console from the server information page.
  2. Type ENTER to select the default, Boot SystemRescueCd using default options.
  3. Enter startx at the root prompt.
  4. When the graphical desktop appears, navigate to System > GParted.
