So you are using the ELRepo packages and there was a kernel ABI change
between your 2.6.32-220 series of kernels and the latest 2.6.32-754
series. Probably more than one but since you skipped the intervening 6
or 7 point releases of CentOS/RHEL, you missed those.

You could run `yum --enablerepo=elrepo update` and it should pick up the
newer kmod-drbd packages and update them. Those stand a much better
chance of working with the newer kernels though I doubt if ELRepo have
rebuilt kmod-drbd83 in years. If that doesn't work then I would look at
removing the current kmod-drbd83 packages and install kmod-drbd84
instead. That's probably a better solution in the long term but it may
mean that you need to review your /etc/drbd.d/* config files and amend
them for any config differences between DRBD 8.3 and 8.4. I know the
current kmod-drbd84 packages work with the current 2.6.32-754 kernels as
I am using them.
