<para> |
51 |
The <command>&dhpackage;</command> is the daemon which is |
52 |
responsible for the node functions in the ganeti system. |
53 |
</para> |
54 |
|
55 |
<para> |
56 |
For testing purposes, you can give the <option>-f</option> |
57 |
option and the program won't detach from the running terminal. |
58 |
</para> |
59 |
|
60 |
<para> |
61 |
Debug-level message can be activated by giving the |
62 |
<option>-d</option> option. |
63 |

<title>ROLE</title> |
66 |
<para> |
67 |
The role of the node daemon is to do almost all the actions |
68 |
that change the state of the node. Things like creating disks |
69 |
for instances, activating disks, starting/stopping instance |
70 |
and so on are done via the node daemon. |
71 |
</para> |
72 |
|
73 |
<para> |
74 |
Also, in some cases the startup/shutdown of the master daemon |
75 |
are done via the node daemon, and the cluster IP address is |
76 |
also added/removed to the master node via it. |
77 |
</para> |
78 |
|
79 |
<para> |
80 |
If the node daemon is stopped, the instances are not affected, |
81 |
but the master won't be able to talk to that node. |
82 |
</para> |

<title>COMMUNICATION PROTOCOL</title> |
87 |
<para> |
88 |
Currently the master-node RPC is done using a simple json-RPC |
89 |
over HTTP(S). |
