Re: [ansible-project] Ansible playbook to check disk space is failing

[Piotr Owcarz]

Hi

You are declaring ansible_mounts as a list of strings. It literally is: ansible_mounts: ['xyz', 'abc']. Ansible is complaining, that the string 'xyz' does not have a 'mount' property. You are obviously missing a step, where you actually check the available space :)

Hi Experts,

I am trying to check the diskspace on remote servers but it failing . Could someone please help.

Playbook.yml

- hosts: all

  gather_facts: no

  vars_files:

      - /etc/ansible/xyz/pre-deploy/vars/main.yml

  tasks:

  - name: Ensure that free space on the tested volume is greater than 15%

    assert:

      that: item.size_available > item.size_total|float * 0.3

      msg: Disk space has reached 85% threshold

    when: item.mount == mountname

    with_items: "{{ ansible_mounts }}"

vars/main.yml

ansible_mounts:

- xyz

- abc

ERROR: 

FAILED! => {"msg": "The conditional check 'item.mount == mountname' failed. The error was: error while evaluating conditional (item.mount == mountname): 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'mount'\n\nThe error appears to have been in '/etc/ansible/xyz/pre-deploy/tasks/disk.yml': line 8, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n  tasks:\n  - name: Ensure that free space on the tested volume is greater than 15%\n    ^ here\n"}

Hi

Ok, I think I know what you're doing here.

ansible_mounts is an ansible fact - a magi variable defined by Ansible during runtime, but you are instructing Ansible not to gater facts with  gather_facts: no, that's why Ansible can not recognize the ansible_mounts variable, so remove the "gather_facts: no" line.

Then, with the following:

  vars_files:
      - /etc/ansible/xyz/pre-deploy/vars/main.yml
you are overwriting the ansible_mounts fact - you loose the information on mounts. Remove the above as well.

Last one

when: item.mount == mountname

mountname is not defined anywhere. This will fail. I don't know what you need it for.

I strongly recommend you to read at least the Ansible tutorial before you continue doing anything with Ansible or you will have a baaad time :)
