How to mount partition when NTFS only

[Gilberto Valentin]

Hello,

I have a playbook that scans for hard drives and mounts them in order to do a backup of the data from those drives. I am able to scan for the drives just fine and I can also mount them (thanks to the Ansible IRC community). The only issue I am having is mounting ONLY when the partition is fstype: ntfs. As you can see below, when I run the parted module, I can see a key value of fstype: ntfs. 

ok: [localhost] => (item=sda) => {

    "changed": false,

    "disk": {

        "dev": "/dev/sda",

        "logical_block": 512,

        "model": "VMware Virtual disk",

        "physical_block": 512,

        "size": 33554432.0,

        "table": "msdos",

        "unit": "kib"

    },

    "invocation": {

        "module_args": {

            "align": "optimal",

            "device": "/dev/sda",

            "flags": null,

            "label": null,

            "name": null,

            "number": null,

            "part_end": "100%",

            "part_start": "0%",

            "part_type": "primary",

            "state": "info",

            "unit": "KiB"

        }

    },

    "item": "sda",

    "partitions": [

        {

            "begin": 1024.0,

            "end": 308224.0,

            "flags": [

                "boot"

            ],

            "fstype": "ntfs",

            "num": 1,

            "size": 307200.0,

            "unit": "kib"

        },

        {

            "begin": 308224.0,

            "end": 33553408.0,

            "flags": [],

            "fstype": "ntfs",

            "num": 2,

            "size": 33245184.0,

            "unit": "kib"

        }

    ],

    "script": "unit 'KiB' print"

}

I use the setup module to scan for the devices and the parted module to see the fstype. Thinking about it further, I should probably just use the parted module to get me both since parted does provide both.

Using parted alone without setup, how can I tell my mount task to just mount ONLY if the fstype is ntfs? Here is my current playbook:

---

## This playbook will backup user data from HD's found

- name: Backup data

hosts: all

connection: local

become: true

become_user: root

become_method: su

#vars_files:

# - vault.yml

#remote_user: root

tasks:

- name: Install jmespath via pip if missing

pip:

name: jmespath

- name: Check for hard drive devices

setup:

filter: ansible_devices

- name: Check for hard drive devices

parted: device=/dev/{{ item }}

register: driveFStype

with_items: "{{ json_query('*.partitions.keys(@)[]') }}"

- name:

mount:

path: "/mnt/{{ item }}"

src: "/dev/{{ item }}"

fstype: ntfs

state: mounted

with_items: "{{ ansible_devices | json_query('*.partitions.keys(@)[]') }}"

The Check for hard drive device task above doesn't work. The rest of the tasks do. I was thinking I could do something like this playbook below to get what I want but it doesn't work either:

---

## This playbook will backup user data from HD's found

- name: Backup data

hosts: all

connection: local

become: true

become_user: root

become_method: su

#vars_files:

# - vault.yml

#remote_user: root

tasks:

- name: Install jmespath via pip if missing

pip:

name: jmespath

- name: Check for hard drive fstype
parted: device=/dev/{{ item }}

register: whichFS

with_items: "{{ json_query('*.partitions.fstype.keys(@)[]') }}"

- name: Check for hard drive devices

parted: device=/dev/{{ item }}

register: whichPartition

with_items: "{{ json_query('*.partitions.keys(@)[]') }}"

- name:

mount:

path: "/mnt/{{ item }}"

src: "/dev/{{ item }}"

fstype: ntfs

state: mounted

with_items: "{{ ansible_devices | json_query('*.partitions.keys(@)[]') }}"
when: "{{ whichFS }}" == ntfs

In summary, I want to mount any device it finds ONLY if it is NTFS

Any suggestions? :)

You should check your with_items: under "Check for hard drive devices"
it's in practice empty.

Kai,

Thanks for the response. Can you elaborate on what you by "it's in practice empty"? From what I can tell, I am parted to then pull the key values for a list of drives. This doesn't fully work based on what I am trying to do. In essence, I am looking for help to accomplish what I want and that would be filtering through partitions that are NTFS only. An example, if you have one, would be great. I am still lost on how to only list out and mount partitions that are NTFS only

json_query is a filter, for a filter to work it need content.
When you only use a filter and not any content it's basically empty.

- name: Check for hard drive devices

parted: device=/dev/{{ item }}
register: driveFStype
with_items: "{{ json_query('*.partitions.keys(@)[]') }}"

Here you only have a filter in with_items, no content at all.

- name:
mount:
path: "/mnt/{{ item }}"
src: "/dev/{{ item }}"
fstype: ntfs
state: mounted
with_items: "{{ ansible_devices |
json_query('*.partitions.keys(@)[]') }}"

Here you have content in the form of the variable ansible_device that's
why this task work and the task above fails.

Yep, I get that...my point is I don't know how to pull the NTFS partition info from the filter. It seems like a nested key pair value and I don't know how to extract it for comparison

[Gilberto Valentin]

I got a bit further. I was able to add the following:

tasks:

    - name: Install jmespath via pip if missing

      pip:

        name: jmespath

    - name: check for hard drive devices

      setup:

        filter: ansible_devices

      tags:

        - test

    - name: get device info

      parted: device=/dev/{{ item.key }} unit=MiB

      register: results

      tags:

        - test

      ignore_errors: yes

      with_dict: "{{ ansible_devices }}"

    - name: mount ntfs partitions

      mount:

        path: "/mnt/{{ item.item }}"

        src: "{{ item.disk.dev }}"

        fstype: ntfs

      when: "item.partitions | length > 0 and item.partitions | selectattr('fstype', 'equalto', 'ntfs') | list | length > 0"

      with_items: "{{ results.results }}"

      tags:

       - test

However, I am getting the following errors:

I was able to resolve this by redoing all of my tasks as follows:

tasks:

    - name: Install jmespath via pip if missing

      pip:

        name: jmespath

    - name: run the setup module for some facts about the hardware

      setup:

        filter: ansible_devices

      tags:

        - new

    - name: check what drives are available

      parted:

        device: /dev/{{ item }}

      with_items: "{{ ansible_devices }}"

      when:

        - item != 'sr0'

      register: result

    - name: get a list of paritions that are only ntfs

      debug:

        msg: "{{ item.0.disk.dev }}{{ (item.0.disk.table == 'loop') | ternary('', item.1.num) }}"

      when: item.1.fstype == 'ntfs'

      with_subelements:

        - "{{ result.results }}"

        - partitions

    - name: mount ntfs partitions

      mount:

        path: "/mnt/{{ item.0.disk.dev }}{{ (item.0.disk.table == 'loop') | ternary('', item.1.num) }}"

        src: "{{ item.0.disk.dev }}{{ (item.0.disk.table == 'loop') | ternary('', item.1.num) }}"

        fstype: ntfs

        state: mounted

      when: item.1.fstype == 'ntfs'

      # when: results.item.value.partitions.fstype == "ntfs"

      with_subelements:

        - "{{ result.results }}"

        - partitions
