Creating Volume, Attaching volume and Mouting it to EC2 instance using Ansible

I have created an Ansible playbook, which performs the following tasks:

  1. Create an EBS volume.
  2. Attach the volume to an existing EC2 instance.

  3. Mount the volume in the instance.

    - name: Creating a Volume
  hosts: all
  sudo: yes
  tasks:

- name: Creating a Volume
  ec2_vol:
    aws_access_key: "{{ lookup('env', 'AWS_ACCESS_KEY_ID') }}"
    aws_secret_key: "{{ lookup('env', 'AWS_SECRET_ACCESS_KEY') }}"
    instance: 'i-7edebfdb'
    volume_size: 5
    device_name: /dev/xvdf
    region: 'ap-northeast-1'
    volume_type: gp2
  register: ec2_vol

 - name: Printing the volume information
   debug: var=ec2_vol

 - name: mounting the volume
   mount: name=/mnt fstype=ext4 state=mounted src=/dev/xvdf

But when I executed the playbook, received the following error.

failed: [172.30.1.237] => {"failed": true}
msg: Error mounting /mnt: mount: wrong fs type, bad option, bad superblock on /dev/xvdf,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

When I perfromed fdisk -l I can see the volume. But it is not mounted.

In dmesg there is can see the error message Can't find ext4 filesystem

How to resolve this issue.

According to your logs, The error clearly mentions there is no file system on Volume. That means you are not formatting (Creating a filesystem) on EBS Volume.

Please include a task to format the Volume with a supported/required filesystem type before you mount.

Hope it helps.
