I wish to get Use percentage for /ihs mount which is 19%.
Here is my playbook code:
- name: Generate JSON data set_fact: "{{ ansible_host }}_{{ item.mount }}: {{
(100 * ((item.size_total - item.size_available) / item.size_available)) |
round(1, 'common') }}" when: item.mount == '/ihs' with_items: '{{
ansible_mounts }}'
However, the output of my playbook run shows 28.5 % usage instead of 19%:
ok: [myhostone] => (item={u'block_used': 2857014, u'uuid':
u'3fa1ec29-aca5-476b-8041-6a7bc6b1efc2', u'size_total': 52701921280,
u'block_total': 12866680, u'mount': u'/ihs', u'block_available': 10009666,
u'size_available': 40999591936, u'fstype': u'ext4', u'inode_total': 3276800,

u'rw,seclabel,relatime,stripe=256,data=ordered'}) => {

},

Can you please tell me why is the percentage of used disk shows 28.5% with
ansible while the df -k shows only 19% used? How can I get the correct
usage i.e 19% to s
