Ansible find volume disk name

I'm attempting to write a playbook to format a certain volume, but I can't get my head around choosing the correct drive

here is what I'm working on 

---
- hosts: all
  gather_facts: no
  remote_user: root
  tasks:
  - name: create file system on storage lun
    filesystem: fstype=xfs  dev=/dev/mapper/mpath*

I'm trying to match any single character after mpath, but * doesn't seem to work.

Wildcards wouldn't work in there. You need to get this information in an additional task or alternatively from the setup module.

Example:

- command: ls /dev/mapper/mpath*
  register: mapper
- filesystem: fstype=xfs dev="{{ mapper.stdout_lines[0] }}"

Haven't tested the above but that is the general idea.
