Clonezilla: Unable to Restore Image to Smaller SSD on Ubuntu 20.04
In this article, we will discuss how to clone an image from a larger SSD to a smaller SSD using Clonezilla on Ubuntu 20.04. We will cover the key concepts and provide a step-by-step guide to help you through the process.
Introduction
Clonezilla is a popular open-source disk cloning tool that allows you to create backups of your disk or restore a disk image to another disk. It is a powerful tool that can be used to migrate your operating system and data to a new disk or to create a backup of your disk in case of a hardware failure.
In this tutorial, we will show you how to use Clonezilla to clone a disk image from a larger SSD to a smaller SSD on Ubuntu 20.04. However, if the target SSD is smaller than the source SSD, you will encounter an error message stating that the target disk is too small.
Preparation
Before we begin, you will need to prepare the following:
- Two SSDs with different sizes
- A USB flash drive with at least 4GB of storage
- A computer running Ubuntu 20.04
Creating a Clonezilla Live USB
To create a Clonezilla Live USB, you can use the following command:
sudo dd if=clonezilla-live-2.8.2-47-amd64.iso of=/dev/sdX bs=4M status=progress oflag=syncReplace /dev/sdX with the device identifier of your USB flash drive.
Cloning the Disk Image
Once you have created the Clonezilla Live USB, you can boot your computer from the USB flash drive. Select the "Start Clonezilla" option and choose the "device-image" mode.
Next, select the source disk and the target disk. If the target disk is smaller than the source disk, you will encounter an error message. To work around this issue, you can use the following command to resize the partition on the target disk:
sudo parted /dev/sdY resizepart 1 100%Replace /dev/sdY with the device identifier of the target disk.
After resizing the partition, you can proceed with the cloning process. Once the cloning process is complete, you can boot your computer from the target SSD and verify that everything is working as expected.
