I am working on ansible exception handling tasks and stuck in an ansible tasks execution handling problem where I need your guide to come over.

I have 2 system host group **system\_a** and **system\_b** and I develop 6 roles and each role have multiple tasks.I execute 2 roles on **syste\_a** and reaming 4 on **system\_b**.

in my case is, if any tasks in a role(1-6) are failed then skip the remains role execution and execution one task end of the playbook on system\_a group host.

How can handle this case in ansible.

Can you help me in this situation?

here is my site.yml

`

`

- host: system\_a  
roles:
- role-1
- role-2
- hosts: system\_b  
roles:
- role-3
- role-4
- role-5
- role-6
- tasks:
- name: restart postfix service  
service: name=postfix state=restarted  
delegate\_to: “{{ item }}”  
loop: “{{ groups[‘system\_a’] }}”

Did you maybe try with serial and max\_fail\_percentage?

both serial and max\_fail\_percentage do not work for this case. because I need to skip the remaining roles.

Skipping the reminder roles/task is not a problem, that just a matter of setting any\_errors\_fatal: true  
The challenge is that you need to run a task afterword, but that is not supported at that level(roles), you have it on task with block/rescue.
