Comment 3 Wenkai Shi 2017-05-02 02:05:52 EDT

Verified with version openshift-ansible-3.3.73-1.git.0.a4580db.el7.noarch. During installation, run a while loop of iptables command on hosts, installer will be slow down at "TASK [os_firewall : Add iptables allow rules]" step, once stop the while loop, installer continue with normal speed.

[root@master ~]# while true; do iptables -nL; done
...

[root@ansible ~]# ansible-playbook -i hosts -v /usr/share/ansible/openshift-ansible/playbooks/byo/config.yml
...
TASK [os_firewall : Add iptables allow rules] **********************************
...
(slow down here during the "while loop" alive)
