LVM

...gonna take a shortcut on this and as a foundation, just paste in ChatGPT generated text instead of retyping it, then add stuff in and modify it.

Blivet

A great GUI tool for managing and creating LVs. But sadly, doesn't exist or work past Rocky 8. When creating a Volume Group BLIVET creates the Partition, Physical Volume, and Volume Group in one swift move.

After creating a Volume Group, move on down to the LVM section (left column under physical drives) and create the Logical Volume and format it (create Labels too).

Command Alternative
