The sections above, guide you though the actions needed to create a synnefo |
30 |
backend. Once you have at least one backend up and running you can go back to |
31 |
the :ref:`cyclades <i-cyclades>` section, add the backend, create a public |
32 |
network and have full synnefo functionality. |
33 |
|
34 |
In the following sections we will refer to the following roles: |
35 |
|
36 |
* ``ganeti`` (all nodes of a Ganeti cluster/synnefo backend) |
37 |
* ``master`` (ganeti master node) |
38 |
* ``router`` |
39 |
|
40 |
Please note that all these roles can be "played" by the same node. |

Prerequisites: |
43 |
~~~~~~~~~~~~~~ |
44 |
|
45 |
``master``: |
46 |
|
47 |
- Available master IP that resolves to FQDN (ganeti.example.com) |
48 |
|
49 |
``ganeti``: |
50 |
|
51 |
- primary interface: `eth0` with IP that resolves to FQDN (nodeX.example.com) |
52 |
- /etc/hosts: hostname should not resolv to 127.* address. |
53 |
- /etc/ssh/ssh_host_rsa_key*: must be identical among all nodes. |
54 |
- extra interfaces: `eth1`, `eth2` (vlans can be used too) |
55 |
- NFS mount point: `/srv/pithos` |
56 |
- lvm: Volume Group named `ganeti` |
57 |

58 |
``router``: |
59 |
|
60 |
- primary interface: `eth0` with public routable IP |
61 |
- extra interfaces: `eth1`, `eth2` (vlans can be used too) connected with ganeti nodes |
