question on LVM exists or not

[subbamma natla]

why am I getting output when " when: ansible_facts['lvm']['lvs']['lv_mysql'] is not defined"

---

- hosts: database

  gather_facts: yes

  tasks:

  - name: check lv_mysql exists

    debug:

      msg: "LV_MYSQL not there"

    when: ansible_facts['lvm']['lvs']['lv_mysql'] is not defined

  - name: check lv_mysql exists

    debug:

      msg: "LV_MYSQL is there"

    when: ansible_facts['lvm']['lvs']['lv_mysql'] is defined

output:

TASK [check lv_mysql exists] **********************************************************************************************************

ok: [mhost5] => {

    "msg": "LV_MYSQL not there"

}

TASK [check lv_mysql exists] **********************************************************************************************************

skipping: [mhost5]

Well,

  Someone else might have a clearer answer, but the way you coded it, the task would be skipped if ln_mysql is not defined.  Did you try adding some verbosity to the ansible-playbook command?  When something like this happens to me, I go right for the -vvvv and that will usually point me in the right direction.
