I discovered Centos 7.2 is not using the newest kernel after updates.
Installed Packages
kernel.x86_64 3.10.0-123.el7 @anaconda
kernel.x86_64 3.10.0-327.36.3.el7 @updates
kernel-devel.x86_64 3.10.0-327.36.2.el7 @updates
kernel-devel.x86_64 3.10.0-327.36.3.el7 @updates
kernel-headers.x86_64 3.10.0-327.36.3.el7 @updates
kernel-tools.x86_64 3.10.0-327.36.3.el7 @updates
kernel-tools-libs.x86_64 3.10.0-327.36.3.el7 @updates
Looks like this is a known bug. Workarounds seem to involve making changes to grub2 which looks like we don't have. What is the best way to reboot with 3.10.0-327.36.3.el7 temporarily and than permanently?
Quick update on this. My data center also confirmed it is a known CentOS bug not updating grub with new kernels. They encouraged me to manually change the kernel listed in /boot/grub/grub.conf. I did and rebooting into the latest kernel was successful.
I see I now have an update to CentOS 7.3 waiting to be done, maybe this will be fixed.
