You should
drbsetup 17 down
drbsetup 18 down

(the network part is still configured...)

Usually, you _first_ unconfigure things,
and only then remove them from the config.

There currently is no way to completely remove "Unconfigured" devices
from /proc/drbd short of a module unload,
but they should no longer show up in drbd-overview.

That is nonsense, I dare say.
If its "Diskless", it does not hold anything in use.
So whatever keeps you from removing things from devmapper,
it is not DRBD.
