How to check file system is mounted?

[Robert F]

Is there a canonical way in Ansible to check to see if a file system is mounted?  The Ansible mount module doesn't appear to provide this capability (or at least the examples don't illustrate how it might be done).  Currently I'm doing the following but it doesn't work:

- name: check if mounted

  command: mount | grep <file_system>

  register: result

- debug: var={{ result.stdout }}

I get the error:

failed... 'Consider using mount module rather than running mount'...

stderr:

Usage:

   mount [-lhV]

   ...

What I'm hoping to replicate is running that command.  If you run it when the file system is mounted and then do "echo $?" you'll get "0".  However if the file system isn't mounted, you'll get "1".

Thank you.

Why not using the "ansible_mounts" fact ?

That seems to be an array of hashes. What would be the best way to check, in your experience?

If you can't get this with the ansible_mounts variable for whatever
reason, then what you're doing here should work, except that in order to
do the pipe, you need to use the 'shell' rather than the 'command' module.

Or:

command: mount

register: m

always_run: True

changed_when: False

...

when: "'/path' not in m.stdout"
