It may be that /usr/lib/drbd/crm_fence_peer.9.sh is equipped to be
used with `fencing resource-and-stonith` and is the correct choice.
The comments suggest that it's designed to work with either
resource-only or resource-and-stonith, although it's less clear how
exactly it works. (The details don't matter much to me at the moment.)

That's correct. The `/sbin/kill-other-node.sh` script in the example
is just a tongue in cheek way of saying, "any script or program that
can forcibly remove a node from the cluster". We can clarify that to
avoid future confusion.

I know you said you don't care about the details at the moment, but
`resource-only` should put a location constraint in the cluster while
`resource-and-stonith` will also request Pacemaker fence the node. The
location constraint would be removed once DRBD successfully resyncs
from the peer.

Best Regards,
Matt
