precheck ssh config (ssh_args) in ansible.cfg - help prevent intermittent hangs
Some internal testing has revealed intermittent hangs when running playbooks. (currently only observed on RHEL7.6)
Small enhancement request to precheck config during install prechecks to see if ssh_args set to a value proved to help some node instances remove the intermittent hangs.
Am able to debug your hang issue , found issue with ssh connectivity .
I found one Ansible link and used this suggestion and able to install successfully on your cluster by changing one paramter in ansible.cfg file. [https://stackoverflow.com/questions/51675831/ansible-stops-connecting-to-the-host-via-ssh]
Believe the connection may be dropping due to the lack of output from your play.
Add the following to your ssh_args in ansible.cfg:
-o ServerAliveInterval=50
I am able to create cluster successfully on your cluster environment using latest ansible code.
