how to abort execution upon a single fail on any host

[Leon Xie]

hi all,

I have the below playbooks:


+++++++++++++++++++++++++++++++++++++++++++++++++++++++
- hosts: aa
  max_fail_percentage: 0
  roles:
    - stop_server

- hosts: allhosts
  max_fail_percentage: 0
  roles:
    - backup_data

- hosts: localhost
  max_fail_percentage: 0
  roles:
    - prepare_data

+++++++++++++++++++++++++++++++++++++++++++++++++++++++
what I get now is that even if any task in stop_server role fail, the task in backup_data for allhosts still runs.

what I want is that if any failure occurs in any host, the other tasks won't be run for the remaining hosts.
is there a way to achieve this?

max_fail_percentage:

​Perhaps ​any_errors_fatal: true might help?

(btw Seems undocumented)

thanks a lot for your suggestion.
I had a try by adding any_errors_fatal: true.
however, it doesn't work.

- hosts: aa
  max_fail_percentage: 0

  any_errors_fatal: true

  roles:
    - stop_server

- hosts: allhosts
  max_fail_percentage: 0
  roles:
    - backup_data

my ansible version is as below:

$ ansible-playbook --version
ansible-playbook 1.9.1
  configured module search path = None

Hi Serge,

your suggestion about any_errors_fatal works for the hosts that in a single play.
if there is another play and one of the hosts in the play is not in the hosts that marked as any_errors_fatal, the tasks in this play will also be executed.
