Greetings all.

I have inherited a pair of Scientific Linux 6 boxes used as front-end load balancers for our DNS cluster. (Yes, I inherited that, too.)

It was time to update them so we pulled snapshots (they are VMWare VMs, very small, 1 cpu, 2G RAM, 10G disk), did a "yum update -y" watched everything update, then rebooted.  Pacemaker kept the system from booting.
Reverted to the snapshot, ran a "yum update -y --exclude=pacemaker\* " and everything is hunky-dory.

# yum list pacemaker\*

I searched clusterlabs.org looking for issues with updates, and came up empty.

# cat /etc/redhat-release
Scientific Linux release 6.5 (Carbon)

... is there something post-install/pre reboot that I need to do?
