Issues with ansible file system mount.

[Karthick Thanigaimani]

Hi,

We are having an issue with one of our components where in the file system says not available even though the device is available (via Ansible).

The instance is spinned up and via ansible we set the facts like 

- set_fact:

    device: /dev/nvme2n1

  when: nvmedev.stat.exists == True

Then attach / mount the volumes as (e.g. vol-a) using 

- name: Attach the existing cold summaries volume if it is found

  ec2_vol:

    id: "{{ ec2_vol_data_cold_summaries.volumes[0].id }}"

    instance: "{{ ansible_ec2_instance_identity_document_instanceid }}"

    device_name: "/dev/xvdf"

    region: "{{ ansible_ec2_instance_identity_document_region }}"

  when: ec2_vol_data_cold_summaries.volumes|length > 0

mount:

    path: /var/cold_summaries

    src: "{{ device }}"

    fstype: ext4

    state: mounted

    opts: noatime

We get the error as below:

TASK [indexer : Mount the volume] *******************************

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Error mounting /var/cold_summaries: mount: special device /dev/nvme2n1 does not exist\n"}

NAME        MAJ:MIN RM SIZE RO TYPE MOUNTPOINT

nvme0n1     259:1    0   4G  0 disk

└─nvme0n1p1 259:2    0   4G  0 part /

nvme1n1     259:0    0  50G  0 disk /opt/

nvme2n1     259:3    0  16T  0 disk

and when I manually mount using mount devicename filesystemname (as below) it works fine.

mount /dev/nvme2n1 /var/cold_summaries

Ansible version details are as below:

ansible 2.8.5

  config file = None

  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

  ansible python module location = /usr/lib/python2.7/site-packages/ansible

  executable location = /bin/ansible

Could you please let us know if there are any recent changes that is causing this issue. Please note that this used to work fine before. 

Thank you.

Regards
