Calculate partition space used in jinja

I have a playbook that uses gather facts, then I use the ansible_mounts fact in a jinja2 template. In this template, I can print out each partition, the total size and total available. What I'd like to do is to also calculate the percentage of space available. I'm trying below, but keep getting a templating error when the playbook runs. Any ideas?

server_mounts.html.j2

<html>

<body>

Partition/Mount Space Report

---

{% for i in play_hosts | sort %}

Host: {{ i }}

{% for m in hostvars[i]['ansible_mounts'] %}

Partition: {{ m.mount }}

Total Space: {{ m.size_total|human_readable(unit="G") }}

Available Space: {{ m.size_available|human_readable(unit="G" }}

{% if m.size_total|int != 0 %}

Space used: {{ 100 * ((m.size_total - m.size.available/m.size_available)) |round(1, 'common') }}

{% endif %}

{% endfor %}

---------------------------------------

{% endfor %}

</body>

</html>

Thanks,

Harry

My apologies. I obviously forgot to add the error. I did find that I was missing a ')' character at the end of the "Total Space" line. But now I get the following:

FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'size'"}

The j2 file is above, but here's the playbook I'm using:

---

- hosts: localhost

become: true

become_method: sudo

gather_facts: yes

tasks:

- name: Print out server mounts

template:

src: /root/server_mounts.html.j2

dest: /var/tmp/server_mounts.html

delegate_to: localhost

run_once: true

I can't find why its complaining about a "size" attribute.

Thanks,

Harry

Hello Harry,

I don't see that problem either, are you really sure that the you posted the content of /root/server_mounts.html.j2?

BTW: That's a really weird location for any part of your Ansible project if you ask me.
