Comment 11 for bug 1864221

On the layered build, can you check whether there's a "drbd.ko" file under the "extra" kernel modules directory? It should look something like this:

controller-1:/home/sysadmin# ls -l /lib/modules/3.10.0-1062*/extra/drbd/drbd.ko
-rw-r--r--. 1 root root 684157 Feb 13 03:51 /lib/modules/3.10.0-1062.1.2.el7.2.tis.x86_64/extra/drbd/drbd.ko
