The problem disappeared after I disable SELinux with the following steps, it works very well. Maybe we need to mention disabling SELinux and probably creating extra firewall policy to enable Lustre inter-node communication in the setup guide.
Edit /etc/selinux/config and make sure the following line is *SELINUX=disabled* *Reboot host. (this is a must, the test environment must have SELINUX disabled, *echo 0 >/selinux/enforce won't work) * * Hope this helps, and thanks for all of your help. Regards, -Jon.
