......@@ -55,6 +55,18 @@ skip this process. The option requires interactive confirmation, as
having two masters on the same cluster is a very dangerous
situation and will most likely lead to data loss.
When the master daemon receives a ``SIGINT`` (Ctrl-C) or ``SIGTERM``
signal, it stops accepting new jobs and prepares to shut down shortly
after jobs running at the time finish. Meanwhile it still responds to
LUXI requests. Pending jobs are re-queued after the daemon is started
again. When a second signal is received, the master daemon terminates
without waiting (it might still need to wait for some threads to
finish). Note that the latter, as well as sending ``SIGKILL``, may leave
the cluster in an inconsistent state.
