Very, very carefully.

Stop the external/sbd resource, so that fencing blocks while you're
doing this.

You can then manually stop the sbd daemon on all nodes (by sending the
node an "exit" message), change the timeout, and restart it.

Once it's running everywhere again, restart the fencing resource.
