Hi Eric, if your distro is el (e.g. RHEL/CentOS/Scientific), the kernel ABI *should* not change during kernel updates, and copying modules from older kernel versions as "weak updates" is not uncommon, following the slogan "old module is better than no module". This is for example the case for CentOS 7 and worked quite well in the past, unfortunately with upgrade to 7.5 the ABI changed nevertheless and caused many systems even to crash when using some old modules, including drbd.
If you build the module on the system that runs it, you might consider installing/building a dkms or akmod package of drbd instead, along with dkms/akmod itself. When booting a new kernel, dkms/akmod will check whether the packaged modules already exist for the running kernel, and if not, they will be built and installed. This works as long as the module source builds well against the kernel source/headers provided and all dependencies and build tools are present.
