The playbook looks solid, but I have to admit, I'm a little disappointed there's no mounting step included. I was hoping to see a full-fledged storage solution implemented.

I agree, but at least the playbook covers the basics of creating logical volumes.

Yeah, it would have been nice to see the mounting step included.

Haha, I wonder if the developer who wrote this playbook has a sense of humor. 'LV Can not be created with following size' - that's a pretty fun way to handle that scenario.

The solution seems clear and well-structured. I especially appreciate the use of the `ignore_errors` flag to handle the potential issues gracefully.

Wow, this is a pretty comprehensive task! I like how it handles the edge cases of the VG not existing and the size not being accommodated. The solution looks well-thought-out.
