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] myotheruser@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 && chmod a+rx /tmp/.ansible_my_user/tmp/ansible-tmp-1438014075.95-221459817104733 && echo /tmp/.ansible_my_user/tmp/ansible-tmp-1438014075.95-221459817104733'

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
BECOME-SUCCESS-xzmbgooensxgrlbezhnlngbagojwbczg; LANG=en_US.UTF-8
LC_CTYPE=en_US.UTF-8 /usr/bin/python
/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'"'"'"'

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. 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
