Hi Team,
I have changed to standard jinja2 template , even then the error is same.
It fails to find xvdb but it finds xvda2 . The syntax to extract UUID is
same and both values are present in the ansible localhost -m setup command
output . This playbook is running on localhost only.
```
UUID={{ ansible_facts['device_links']['uuids']['xvda2'][0] }} / {{
ansible_facts['mounts'][0].fstype }} defaults 0 0
UUID_home={{ ansible_facts['device_links']['uuids']['xvdb'][0] }} /home
{{ ansible_facts['mounts'][0].fstype }} defaults 0 0
UUID_var={{ ansible_facts['device_links']['uuids']['xvdc'][0] }} /var
{{ ansible_facts['mounts'][0].fstype }} defaults 0 0
UUID_swap={{ ansible_facts['device_links']['uuids']['xvdd'][0] }} swap
swap defaults 0 0
```
Regards
Sachin Kumar
