50 | a8083063 | Iustin Pop | <para> |
51 | a8083063 | Iustin Pop | The <command>&dhpackage;</command> is the daemon which is |
52 | 320d986d | Iustin Pop | responsible for the node functions in the ganeti system. |
53 | a8083063 | Iustin Pop | </para> |
54 | a8083063 | Iustin Pop | |
55 | a8083063 | Iustin Pop | <para> |
56 | a8083063 | Iustin Pop | For testing purposes, you can give the <option>-f</option> |
57 | a8083063 | Iustin Pop | option and the program won't detach from the running terminal. |
58 | a8083063 | Iustin Pop | </para> |

60 | 320d986d | Iustin Pop | <para> |
61 | 320d986d | Iustin Pop | Debug-level message can be activated by giving the |
62 | 320d986d | Iustin Pop | <option>-d</option> option. |

65 | a8083063 | Iustin Pop | <title>ROLE</title> |
66 | a8083063 | Iustin Pop | <para> |
67 | a8083063 | Iustin Pop | The role of the node daemon is to do almost all the actions |
68 | a8083063 | Iustin Pop | that change the state of the node. Things like creating disks |
69 | a8083063 | Iustin Pop | for instances, activating disks, starting/stopping instance |
70 | a8083063 | Iustin Pop | and so on are done via the node daemon. |
71 | a8083063 | Iustin Pop | </para> |
72 | a8083063 | Iustin Pop | |
73 | a8083063 | Iustin Pop | <para> |
74 | 320d986d | Iustin Pop | Also, in some cases the startup/shutdown of the master daemon |
75 | 320d986d | Iustin Pop | are done via the node daemon, and the cluster IP address is |
76 | 320d986d | Iustin Pop | also added/removed to the master node via it. |
77 | 320d986d | Iustin Pop | </para> |
78 | 320d986d | Iustin Pop | |
79 | 320d986d | Iustin Pop | <para> |
80 | a8083063 | Iustin Pop | If the node daemon is stopped, the instances are not affected, |
81 | a8083063 | Iustin Pop | but the master won't be able to talk to that node. |

87 | a8083063 | Iustin Pop | <para> |
88 | 320d986d | Iustin Pop | Currently the master-node RPC is done using a simple json-RPC |
89 | 320d986d | Iustin Pop | over HTTP(S). |
