1/3/2018: Lulu: no firmware update from Michael. yum updated two nodes and forced fsck. calc02 yum update had many conflicting issues so I did "yum --skip-broken updated" to work around those errors. Both calc01 and calc02 didn't pick up ip address after reboot. 'service network restart" fixed the issue. I need run "systemctl status network.service" next time to see if I can find the reason next time I reboot the system.
