It would be strange if AWS control API for node1 would be serialized with
control for node2. In fact fence_aws suggests that both can happen in parallel
and tries to be smart about it:
if (get_self_power_status(conn,my_instance) == "ok"):
conn.instances.filter(InstanceIds=[options["--plug"]]).stop(Force=True)
logger.info("Called StopInstance API call for %s",
options["--plug"])
else:
logger.info("Skipping fencing as instance is not in running
status")
Even with this in place, some delay seems like a good idea because control API
is probably not that fast (a manual fence test can show how long it takes to
kill
a node).
