WSL Management
Let's Manage WSL(ext4.vhdx) properly.
We have installed WSL (Windows Subsystem for Linux) on Windows and can now use Ubuntu.
WSL, Running Linux on Windows
When Ubuntu is installed on WSL, a file called ext4.vhdx is created. Ubuntu is managed and stored in a virtual disk file called ext4.vhdx. Since I plan to conduct various tests, there will be times when I need to revert to a previous version. VirtualBox provides a snapshot feature, but unfortunately, WSL does not. Therefore, I will use WSL’s export and import functions to manage system versions.
Linux(Ubuntu), Export & Import
When installing various packages on Ubuntu, the packages are deleted, but the size of ext4.vhdx does not decrease. To resolve this, you need to use diskpart to clean up the files. This program is used for disk cleanup. Enter the following commands in order.
(Option) Ollama on Ubuntu
I wrote this post as a review of this topic.
Cleans up the disk
Run the diskpart command. This program cleans up the disk(ext4.vhdx).
select vdisk file="D:\01.WSL\ext4.vhdx"
attach vdisk readonly
compact vdisk
detach vdisk

Stop all docker container
If you proceed with exporting Ubuntu while the container in use is still active, a warning about data consistency issues will appear (though the process will still continue). Therefore, it is recommended to stop the relevant container before proceeding with the export.
docker compose -p ds2man stop
docker stop mysql

Import Ubuntu
Be cautious: if you use wsl --unregister Ubuntu, the ext4.vhdx file will also be deleted!!! Use it carefully.
wsl --unregister Ubuntu
wsl --import Ubuntu "D:\01.WSL" "D:\01.WSL\ubuntu-1-install_wsl.tar"
