LVM vg space in when statements

[Darryl Scott]

I have searched the group but couldn't find the answer to my problem.

I have a playbook that uses when clause for available space in volume group.  I keep getting format errors when trying to run it.  I have tried several different variations of the quotes in the statement but can't seem to get it to work. 

---
- hosts: all
  become: yes
  tasks:
    - name: Create Logical volume when space is more than 1G
      lvol:
        vg: vms
        lv: lv2
        size: 850m
      when: 'vms' in ansible_facts['lvm']['vgs'] and ansible_facts['lvm']['vgs']['free_g'] > '1.00'

ERROR! Syntax Error while loading YAML.
  did not find expected key

The error appears to be in '/home/automation/plays/logvols.yml': line 10, column 19, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

        size: 850m
      when: 'vms' in ansible_facts['lvm']['vgs'] and ansible_facts['lvm']['vgs']['free_g'] > 1.00
                  ^ here
This one looks easy to fix. It seems that there is a value started
with a quote, and the YAML parser is expecting to see the line ended
with the same kind of quote. For instance:

    when: "ok" in result.stdout

Could be written as:

   when: '"ok" in result.stdout'

Or equivalently:

   when: "'ok' in result.stdout"

Here is setup module run for ansible_lvm:
