Anyone know why the changed\_when is not reflected in the output initially? Only in the summary?

Here’s the code:

- name: disk space check  
debug:  
msg: “{{ item.mount }} failed check for {{ item.block\_available \* 4/1024000 }} free GB (Needed {{ pre\_check\_filesystems[item.mount] }})”  
when: item.mount in pre\_check\_filesystems  
changed\_when: item.block\_available \* 4/1024000|float \< pre\_check\_filesystems[item.mount]|float  
with\_items:
- "{{ ansible\_mounts }}

And the output (abbreviated for readabvlity):  
PLAY [all] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

}

mhg-desk-l09 : **ok=2 changed=1** unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

So one of those checks should trigger a “changed” - and it does in the summary, but not in the body of the output. Another thing I just noticed . . . there were 2 tasks, one was ok, the other was changed, but ok=2 in the summary

Any thoughts would be appreciated

Thanks a lot,  
Guy

This appears to be a bug in the default callback plugin, and only with `debug`. If you use some other task like `ping`, it would show it.

The callback plugin “cleans” the result using `self._clean_results` in `v2_runner_item_on_ok` which strips `changed` from `debug` tasks, as such the callback no longer has knowledge of whether the iteration resulted in a change.

I’d recommend filing an issue on github.
