Changing ext4 partition using GParted?

I asked ChatGPT if it was possible to change the partition size of an ext4 file system using GParted. I was provided with instructions (see below) but I am stuck at Step #4. After I select the ext4 partition and right click, when I select “Resize/Move”, changing the size isn’t possible. See see here for an image of what GParted looks like to me:

What am I doing wrong? Is it possible to change the size and shrink or reformat an existing partition without having to reinstall my operating system and starting from scratch?

Yes, you can achieve the same outcome using the graphical partitioning tool GParted. GParted provides a user-friendly interface for managing partitions and filesystems, making it a popular choice for resizing ext4 filesystems and partitions. Here’s how you can use GParted to resize an ext4 filesystem and partition:

1. Install GParted:
If GParted is not already installed on your system, you can install it using your package manager. For example, on a Debian-based system, you can use the following command:

$ sudo apt-get install gparted

2. Open GParted:
Launch GParted from your system’s application menu or by running sudo gparted in the terminal.
3. Select the Target Drive:
Choose the drive that contains the ext4 filesystem and partition you want to resize from the drop-down menu in the top-right corner of the GParted window.
4. Shrink the Filesystem:
Right-click on the ext4 partition you want to resize and select “Resize/Move.” In the Resize/Move dialog, you can adjust the size of the filesystem by dragging the partition boundary or by entering the desired size. This step resizes the ext4 filesystem to make space for the new partition.
5. Apply the Changes:
After resizing the filesystem, click the “Apply” button in GParted to apply the changes. GParted will execute the filesystem resize operation.
6. Resize the Partition:
Once the filesystem resize is complete, you can again right-click on the partition and select “Resize/Move.” Adjust the partition size to use the newly allocated space, either by dragging the partition boundary or entering the size manually.
7. Apply the Changes:
Click “Apply” to execute the partition resize operation. GParted will adjust the partition size to match the new size of the ext4 filesystem.
8. Resize the Filesystem Again (Optional):
If the partition size was increased, you might want to resize the ext4 filesystem to use the entire partition. Right-click on the ext4 partition and choose “Resize/Move.” Then, expand the filesystem to fill the entire partition and apply the changes.

Remember that whenever you are working with partitioning and filesystem operations, there is a potential for data loss if not done correctly. It’s always a good practice to back up your important data before making any changes. Additionally, understanding the tools and the process thoroughly is essential to avoid unintended consequences.

It cant be mounted.
(for that and other reasons you want to use another system to resize it)

Why would you ask artificial intelligence your question when you can ask ACTUAL intelligence here?

No judgment, just curious.

You cannot shrink or move a ext4 partition when it is mounted. Only growing is possible when mounted. The simple reason is that it is not a COW (copy-on-write) fIlesystem, but has a fixed table.

You would need to boot a live session and do it there while it is unmounted.

Hello Megavolt. Thank you for providing the solution. This makes 100% sense. I should have thought of this.

Haha. Yes, I have a special use case and figured with 1 TB in total to spare, why not?

ChatGPT is faster to provide a quick fix. Additionally, it’s just a good starting point to begin any type of research - - whether troubleshooting Linux or writing a social sciences essay. AI is a companion and not a full replacement. That’s the purpose of GitHub Copilot. AI can’t replace software developers yet. AI just helps provide quick additional insight into a traceback. Like when I am building my Django projects, when I feed it a perplexing and non-descript traceback for example, ChatGPT will return 5 novel suggestions to identify the root cause that I never thought of. Whereas, by comparison, writing a Stack Overflow question could take me 2 hours. But with ChatGPT, I arrive at a resolution in just a few minutes. It’s a time saver.
