The below task is waiting for long time, I would like to timeout after 5 minutes.
- name: Get disk size from server1
shell: time df -h
delegate_to: "server-1"
ignore_errors: true
Tried with wait_for and timeout. Both are not working.
Can you please suggest hwo to handle a timeout with a delegate_to task?
Like to timeout this task after 5 minutes but a timeout attribute are not supported in delegate_to.
Please let me know alternate way to timeout.
Run the task asynchronously. See Asynchronous actions and polling. For example, set async: 300 to timeout after 5 minutes. To poll with the period of 5 seconds set poll: 60
- name: Get disk size from server1
shell: time df -h
delegate_to: server-1
run_once: true
ignore_errors: true
async: 300
poll: 60
Test it. For example, given the inventory
shell> cat hosts
test_11
test_13
The below playbook runs the task asynchronously with a timeout of 15 seconds while the command sleeps 20 seconds. The play will poll the command periodically every 5 seconds and then the task will timeout
shell> cat pb.yml
- hosts: all
tasks:
- command: date
register: out
- debug:
var: out.stdout
- command: sleep 20
register: out
delegate_to: test_13
run_once: true
ignore_errors: true
async: 15
poll: 3
- debug:
msg: Play running ...
run_once: true

In order to get the disk size from a Remote Node it is recommend to gather_facts. See in example the minimal playbook
---
- hosts: test
become: false
gather_facts: false
tasks:
- name: Gather date and time only
setup:
gather_subset:
- 'hardware'
- '!min'
- name: Show Gathered Facts
debug:
msg: "{{ ansible_facts }}"
Since the information about the Remote Node will be gathered from the Control Node there is also no need to push a job to a Remote Node and initiating a connection back from there, unless one like to add unnecessary complexity.
Delegating tasks is to
... perform a task on one host with reference to other hosts ... ideal for managing nodes in a load balanced pool or for controlling outage windows.

Provide the timeout as part of shell command as listed below:
- name: Get disk size from server1
shell: timeout 30s time df -h
delegate_to: "server-1"
ignore_errors: true
