A centosplus kernel update (2.6.9-55.0.6) came out. Because the kernel
and kmod-drbd were pushed out at the same time, there was no need to
hold the kernel update until kmod-drbd becomes available.  However,
yum update failed .  Turns out kmod-drbd needed to be excluded from
the extras repo. This was because centosplus is given a lower priority
than extras and yum tried to pull kmod-drbd (for the standard kernel)
from the extra repo.

So, the answer to the situation above (which is the case with my test
machine) is that you need to exclude kmod-drbd from extra and that as
far as kernel and kmod-drbd come out together, installation is done
all automatic.
