Hi
I was trying to make report for free space in vg, but I have a problems,
it's look like jinja doesn't like me::))
ansible_lvm
},
"vgs": {
"vg_root": {
"free_g": "0",
"num_lvs": "2",
"num_pvs": "1",
"size_g": "19.00"
},
"vgswap": {
"free_g": "1.50",
"num_lvs": "1",
"num_pvs": "1",
"size_g": "1.75"
},
"vgdata": {
"free_g": "1.80",
"num_lvs": "1",
"num_pvs": "1",
"size_g": "1.75"
- name: vg free
copy:
content: |
{% for vg in ansible_lvm %}
{{ vg.vgs }} {{ vg.free_g }} GB
{% endfor %}
dest: /tmp/vg-free-vgs
but it keep telling me that I didn't defined variable vgs: (The task
includes an option with an undefined variable. The error was: 'str object'
has no attribute 'vgs') .
Can you please help me once again with this? Thanks
