Ansible playbook to check OS and given mount points - ansible

Question

Below is my playbook to check to verify OS and Mount points. Getting below error and couldn't debug it. The issue seems to be with the later part "Verify Mount points"
---
- hosts: all
gather_facts: true
vars:
M1: ['RedHat','7']
M2: ['/u01','/u02']
tasks:
- name: "Verify OS"
when: >
not ((ansible_os_family == M1[0] and ansible_distribution_major_version == M1[1]))
fail:
msg: "OS not supported"
- name: "Verify Mount Points"
with_items: ansible_mounts
when: >
not ((item.mount == M2[0] and item.mount == M2[1]))
fail:
msg: "Mount Point doesn't exist"
Output:
ansible-playbook -i dbservers test.yml

First, you need to set gather_facts: true when using ansible defined variables.
Second, try to focus on the main issue here. Something along these lines should work:
---
- hosts: all
gather_facts: true
vars:
M1: ['RedHat','7']
M2: ['/u01','/u02']
tasks:
- name: "Verifying os and mount points"
debug:
msg: "{{ item }}"
loop:
- ansible_os_family
- ansible_distribution_major_version
- ansible_mounts
when:
- not item.ansible_os_family == 'M1[0]' # you could also replace 'M1[0]' with 'Redhat'.
- item.ansible_distribution_major_version == 'M1[1]'. # you could also replace 'M1[1]' with '7'.
- fail:
msg: "mount points not correctly"
loop: ansible_mounts
when:
- item.mount is defined
- item.mount != 'M2[0]'
- item.mount == 'M2[1]'
You shouldn't specify multiple fails in a single task, as fail is it's own task.
