Upgrade to Synnefo v0.14.10 |
---|---|
2 |
^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
3 |
|
4 |
Synnefo v0.14.10 supports both Debian Squeeze and Wheezy. However, since |
5 |
v0.14.10, Synnefo supports only Ganeti >= 2.8. This means that at least the |
6 |
Ganeti nodes of a Synnefo deployment should run on Wheezy. |
7 |
|
8 |
To upgrade to Synnefo v0.14.10 one needs to upgrade both Synnefo and Ganeti |
9 |
during the same upgrade cycle, so some minimal service downtime is needed. |
10 |
As always, VMs, Networks and Files will remain usable during the upgrade. |
11 |
|
12 |
Since this is an upgrade to a minor version, no special upgrade operations |
13 |
are needed except from the package upgrades. |

1. Bring down the services |
17 |
========================== |
18 |
|
19 |
First, bring all services (Synnefo and Ganeti) down: |
20 |
|
21 |
.. code-block:: console |
22 |
|
23 |
root@astakos-host# /etc/init.d/gunicorn stop |
24 |
root@cyclades-host# /etc/init.d/gunicorn stop |
25 |
root@pithos-host# /etc/init.d/gunicorn stop |
26 |
|
27 |
|
28 |
root@ganeti-master-host# /etc/init.d/ganeti stop |
29 |
root@ganeti-master-host# /etc/init.d/snf-ganeti-eventd stop |
30 |
root@ganeti-nodeX-host# /etc/init.d/ganeti stop |
31 |
|
32 |
root@cyclades-host# /etc/init.d/snf-dispatcher stop |
33 |
|
34 |
|
35 |
2. Upgrade Ganeti |
36 |
================= |
37 |
|
38 |
Once, everything is stopped, upgrade Ganeti following the official upgrade notes |
39 |
found here: |
40 |
|
41 |
`Ganeti upgrade notes <http://docs.ganeti.org/ganeti/2.8/html/upgrade.html>`_ |
42 |
|
43 |
In a nutshell: |
44 |
|
45 |
Install packages |
46 |
---------------- |
47 |
|
48 |
Install the new Ganeti packages. To be able to use hotplug (which will be part |
49 |
of the official Ganeti 2.10), we recommend using our Ganeti packages with |
50 |
version: ``snf-ganeti=2.8.2+snapshot1+b64v1+hotplug3+ippoolfix+rapifix+netxen+lockfix2-1~wheezy`` |
51 |
|
52 |
.. code-block:: console |
53 |
|
54 |
root@ganeti-master-host# apt-get install snf-ganeti ganeti-htools ganeti-haskell |
55 |
root@ganeti-nodeX-host# apt-get install snf-ganeti ganeti-htools ganeti-haskell |
56 |
|
57 |
.. note:: Make sure you install all three Ganeti packages to all hosts. |
58 |
Also all packages should have the same version. |
59 |
|
60 |
Upgrade |
61 |
------- |
62 |
|
63 |
Upgrade Ganeti's configuration (make sure you do all backup and dry-run steps as |
64 |
described in the official guide): |
65 |
|
66 |
.. code-block:: console |
67 |
|
68 |
root@ganeti-master-host# /usr/share/ganeti/cfgupgrade |
69 |
|
70 |
Start Ganeti |
71 |
------------ |
72 |
|
73 |
Start Ganeti and re-distribute the configuration to all Ganeti master candidates: |
74 |
|
75 |
.. code-block:: console |
76 |
|
77 |
root@ganeti-master-host# /etc/init.d/ganeti start |
78 |
root@ganeti-nodeX-host# /etc/init.d/ganeti start |
79 |
|
80 |
root@ganeti-master-host# gnt-cluster redist-conf |
81 |
|
82 |
root@ganeti-master-host# /etc/init.d/ganeti stop |
83 |
root@ganeti-nodeX-host# /etc/init.d/ganeti stop |
84 |
|
85 |
|
86 |
3. Upgrade Synnefo |
87 |
================== |
88 |
|
89 |
Install packages |
90 |
---------------- |
91 |
|
92 |
Install the new v0.14.10 packages on all hosts according to your deployment. |
93 |
|
94 |
|
95 |
4. Start all services |
96 |
===================== |
97 |
|
98 |
Once, everything is installed successfully, start all services |
99 |
(Synnefo and Ganeti): |
100 |
|
101 |
.. code-block:: console |
102 |
|
103 |
root@cyclades-host# /etc/init.d/snf-dispatcher start |
104 |
|
105 |
root@ganeti-master-host# /etc/init.d/snf-ganeti-eventd start |
106 |
|
107 |
root@ganeti-master-host# /etc/init.d/ganeti start |
108 |
root@ganeti-nodeX-host# /etc/init.d/ganeti start |
109 |
|
110 |
root@astakos-host# /etc/init.d/gunicorn start |
111 |
root@cyclades-host# /etc/init.d/gunicorn start |
112 |
root@pithos-host# /etc/init.d/gunicorn start |
