You don't want to run either of those kernels. Both have high severity
security vulnerabilities present and unfixed. You need to be using
CentOS 6.8 and the latest kernel which was released last week -
kernel-2.6.32-642.13.1.el6. You should be updating your entire system to
6.8 as there are numerous other high severity security vulnerabilities
present in all versions prior to 6.8.

You can find kmod-drbd84 packages in the ELRepo repository (actually
there are drbd84 8.4.9 packages in elrepo-testing). DRBD 8.3 has been
EOL for some years now and 8.4 is current in the 8.x series. ELRepo also
has kmod-drbd83 (8.3.16) packages available but since 8.3 is EOL and you
have to update anyway, it's probably better to skip and go straight to 8.4.
