.. admonition:: Why a fully qualified host name |
|

|
|
111 |
Although most distributions use only the short name in the /etc/hostname |
|
112 |
file, we still think Ganeti nodes should use the full name. The reason for |
|
113 |
this is that calling 'hostname --fqdn' requires the resolver library to work |
|
114 |
and is a 'guess' via heuristics at what is your domain name. Since Ganeti |
|
115 |
can be used among other things to host DNS servers, we don't want to depend |
|
116 |
on them as much as possible, and we'd rather have the uname() syscall return |
|
117 |
the full node name. |
|
118 |
|
|
119 |
We haven't ever found any breakage in using a full hostname on a Linux |
|
120 |
system, and anyway we recommend to have only a minimal installation on |
|
121 |
Ganeti nodes, and to use instances (or other dedicated machines) to run the |
|
122 |
rest of your network services. By doing this you can change the |
|
123 |
/etc/hostname file to contain an FQDN without the fear of breaking anything |
|
124 |
unrelated. |
