According to the gulm.5 man page:
heartbeat_rate
The rate at which the heartbeats are checked by the
server in seconds. Two-thirds of this time is the
rate at which the heartbeats are sent. Default is
15.
allowed_misses
How many consecutive heartbeats can be missed be-
fore we mark the node expired. Default is 2.
Remember that allowed_misses+1 is the "actual" node death time. So,
with the defaults, that's 45 seconds - not 30. (important!)
<cluster>
...
<gulm heartbeat_rate="10" allowed_misses="5" />
<!-- (5+1)*10 second failure recovery -->
...
</cluster>
