Logical volume management

Logical Volume Management (LVM) is like playing with Legos. You have a bunch of small Legos (physical disks) and you want to use them to make something bigger and more useful, like a castle (storage for files and documents).

First, you have to gather all the Legos you want to use and connect them together (create a physical volume). This way, you have a bigger space to work with.

Next, you divide that space into smaller, more manageable pieces called logical volumes. This way, you can organize your castle into different areas like the kitchen, bedrooms, and living room. Each logical volume is like a separate room in your castle.

You can create new logical volumes, resize, or even remove them if you decide you don't need that extra bedroom anymore. You can also move logical volumes around to different physical disks if you want to change the layout of your castle.

What's great about LVM is that you can do all of this without losing any of your files. So, if you decide you need to make changes to the castle, you can do it without worrying about losing any of your precious Legos.

In summary, LVM is like playing with Legos to create a bigger and more organized space for your files and documents. You can create, resize, and move different rooms around without losing any of your Legos.
