Ansible 2.0: Synchronize module is hanging

[Corwin Brown]

Hey gang,

I've been having some issues with the synchronize module in v2. Here's the code that calls it:

- name: Install to Publish Directory
  synchronize:
    src: "{{ tmp_dir }}/"
    dest: "{{ publish_directory }}/{{ instance_name }}"
    delete: yes
    recursive: yes
    mode: push
  delegate_to: "{{ inventory_hostname }}"

This gets called and just hangs with this output:

TASK [restcs_deploy : Install to Publish Directory] *******************

I included the stacktrace from the Control-C in case that's helpful, but that hung like that for about an hour. I tried to merge in:

https://github.com/ansible/ansible/pull/12783

But I'm still having the issue. It's worth noting that the playbook does have "become: yes", and I'm proxying through a jumphost, but all of this works fine in 1.9

Any Thoughts?

Corwin:

I had this problem also... including sometimes not giving any output at all...

In my case, i had a with_items clause and what seemed to help was to add a when clause above the with_items and verify all the attributes are defined.

The other thing i've found with delegate_to is having all the variables defined for that host.

So what you might try to confirm/deny this is:

- name: Install to Publish Directory

  debug: var=tmp_dir
  delegate_to: "{{ inventory_hostname }}"

- name: Install to Publish Directory

  debug: var=instance_name
  delegate_to: "{{ inventory_hostname }}"

- name: Install to Publish Directory

  debug: var=publish_directory
  delegate_to: "{{ inventory_hostname }}"

That's my $0.02... good luck.
