Hi
copy doesn't work for me. I have 2 VG and with the copy module it looks
like it rewrites the first occurrence of VG in loop, linenifile works as it
should.
- name: vg free
copy:
dest: /tmp/file-copy
content: "VG: {{ item.key }} free {{ item.value.free_g }} GB"
loop: "{{ ansible_lvm.vgs|dict2items }}"
TASK [crate /tmp/file-copy]
*************************************************************************************************************
changed: [servera]
TASK [vg free]
**************************************************************************************************************************
changed: [servera] => (item={'key': 'apache-vg', 'value': {'size_g':
'0.49', 'free_g': '0.12', 'num_lvs': '2', 'num_pvs': '2'}})
changed: [servera] => (item={'key': 'vg_root', 'value': {'size_g': '19.00',
'free_g': '0', 'num_lvs': '2', 'num_pvs': '1'}})
PLAY RECAP

[student@ansiblem ]$ ansible -m shell -a "cat /tmp/file-copy" servera

VG: vg_root free 0 GB
lineinfile:
- name: vg free
lineinfile:
path: /tmp/file-lineinfile
line: "VG: {{ item.key }} free {{ item.value.free_g }} GB"
loop: "{{ ansible_lvm.vgs|dict2items }}"
ansible -m shell -a "cat /tmp/file-lineinfile" servera
servera | CHANGED | rc=0 >>
VG: apache-vg free 0.12 GB
VG: vg_root free 0 GB
I should probably use jinja2 and template module?
