having two masters on the same cluster is a very dangerous |
56 | 56 |
situation and will most likely lead to data loss. |

When the master daemon receives a ``SIGINT`` (Ctrl-C) or ``SIGTERM`` |
|
62 |
signal, it stops accepting new jobs and prepares to shut down shortly |
|
63 |
after jobs running at the time finish. Meanwhile it still responds to |
|
64 |
LUXI requests. Pending jobs are re-queued after the daemon is started |
|
65 |
again. When a second signal is received, the master daemon terminates |
|
66 |
without waiting (it might still need to wait for some threads to |
|
67 |
finish). Note that the latter, as well as sending ``SIGKILL``, may leave |
|
68 |
the cluster in an inconsistent state. |
