CC @russoz since you rewrote that module.

Hi @Dhiren-sys

Thanks for reporting this error.

That message happens when the return status of mksyb is not zero, which is meant to be failure. The possibilities I see are:

• mksysb failed due to specific environmental conditions (meaning the Ansible module failed as expected for the given parameters)
• the Ansible module screwed things up, crafting an invalid command line
• mksysb has more than one success exit code. For example, terraform return code is success if 0 or 2 (maybe 1 as well, too lazy to check now).

Because the message does not provide enough details, we cannot tell which case it was.

I have improved the module's output in #6269 , could you please run it again using the code from that PR, and please use ansible-playbook -vvvv. Paste the result in here so we can understand why mksysb return code is not zero.

Good Day, I can see the detailed error message now, the failure was due to insufficient space in "/" filesystem on the destination host which I fixed and then the ansible playbook completed successfully. Regards, Dhiren
