Looks like a well-crafted playbook. I'm curious to see how it handles the case where the VG has just enough space for an 800M LV but not 1500M.

Yes, it's good that it can adjust the LV size based on available space in the VG.

This is a solid solution! The only thing I would suggest is to add a task to mount the LV, just in case the user wants to use it immediately.

The solution is comprehensive and covers all the requirements. I wonder if there's a way to make the size more flexible, like accepting it as a parameter?

I like how the solution uses the `debug` module to print informative messages. It's a nice way to provide feedback to the user.

The solution uses the `lvol` module, which is a nice touch. It also checks for the existence of the VG and adjusts the LV size accordingly. Very well-thought-out!
