Bug - infra.osbuild.export_compose no space left on device

[Thulium-Drake]

Hi there,

I'm running into an issue when downloading an image with the export_compose module:

The task:

---
- name: 'Download result'
  hosts: 'edge_image_builder'
  tasks:
    - name: 'Download result'
      infra.osbuild.export_compose:
        compose_id: 84e02a8f-3dc7-44a3-a6cf-0bdee7e0b187
        dest: /var/cache/edge_result/84e02a8f-3dc7-44a3-a6cf-0bdee7e0b187.tar

When running the task above, I see the following error:

TASK [Download result] ***************************************************************************************************
fatal: [m-a15-01.rh.lab]: FAILED! => changed=false 
  msg: Failure downloading http://localhost/api/v1/compose/image/84e02a8f-3dc7-44a3-a6cf-0bdee7e0b187, [Errno 28] No space left on device

However, when running this 'by hand':

[root@m-a15-01 edge_result]# composer-cli compose image 84e02a8f-3dc7-44a3-a6cf-0bdee7e0b187
84e02a8f-3dc7-44a3-a6cf-0bdee7e0b187-commit.tar
[root@m-a15-01 edge_result]# ls -alh
total 2.4G
drwx------.  2 root root   61 Jul  3 18:53 .
drwxr-xr-x. 16 root root 4.0K Jul  3 17:21 ..
-rw-------.  1 root root 2.4G Jul  3 18:53 84e02a8f-3dc7-44a3-a6cf-0bdee7e0b187-commit.tar

I even made /tmp and /var/tmp bigger (in case the module wants to stash it there, there's plenty room everywhere:

[root@m-a15-01 edge_result]# df -h /var/tmp /var /tmp
Filesystem                Size  Used Avail Use% Mounted on
/dev/mapper/rhel-var_tmp   12G  120M   12G   1% /var/tmp
/dev/mapper/rhel-var      110G   22G   89G  20% /var
/dev/mapper/rhel-tmp       12G  120M   12G   1% /tmp

What's going on?

The traceback:
