[ansible-project] How to debug very simple hanging playbook

[Olivier Lauret]

Hi all, I was wondering if there was away to debug a very simple playbook
when it is hanging.


### Playbook:
- name: Install app on my servers
hosts: my_hosts
gather_facts: no
remote_user: my_user
su: yes

roles:
- app_install


#### app_install role (under tasks/main.yml)
- name: query whoami
shell: whoami


It always hangs at the this level:

*[PROJECT] ***@myprodserver# ansible-playbook -i hosts -k
--ask-su-pass my_playbook.yml -vvvv*
*SSH password:*
*SU password[defaults to SSH password]:*

*PLAY [Install app on my servers] *************************************

*TASK: [app_install | query whoami] ****
*<my_server.mydomain.com> ESTABLISH CONNECTION FOR USER: my_user on PORT 22
TO my_server.mydomain.com*
*<my_server.mydomain.com> REMOTE_MODULE command whoami #USE_SHELL*
*<my_server.mydomain.com> EXEC /bin/sh -c 'mkdir -p
/tmp/.ansible_my_user/tmp/ansible-tmp-1438014075.95-221459817104733 &&

/tmp/.ansible_my_user/tmp/ansible-tmp-1438014075.95-221459817104733/command;
rm -rf /tmp/.ansible_my_user/tmp/ansible-tmp-1438014075.95-221459817104733/

/dev/null 2>&1'"'"'"'*

And nothing else!

Ping works on this server.

Any idea?

Hello all,

The problem still persists but I have more information:


- Ansible version: ansible 1.9.1
- Everything works if I am NOT using "su"
- I can run manually on the server the last ansible command displayed in
my log.
- The password prompt is "Password:"
- Gather facts works fine
- Python 2.6.6
- Linux machine

Is it something related to the "Password:" prompt? How to find this out?


Regards,

Olivier

try logging onto the machine and run this by hand:

/bin/sh -c 'su root -c "/bin/sh -c '"'"'echo

Hello Brian,

Thank you for your answer. I have tried that and it is working fine. Thisi
is reference to the "Password:" I mentioned earlier.

The problem seems to be related to the version of ansible. It is working
fine in 1.6.10 but not in 1.9.1

I am testing now the latest stable version (1.9.2-1).

Regards,
Olivier

Hi All,

I have tested the latest version and I have the same behaviour. So, so far
, only works in 1.6.10. I guess, this is a regression.

Hi All,

I finally found the issue. It is related to the bug #9847
<https://github.com/ansible/ansible/issues/9847>. If the user doesn't have
a home folder assign, we have this issue. The workaround is pretty easy and
well explained in the bug report. Thank you @arlinton and Brian for your
help.

Regards,
Olivier
