Synnefo v0.14.10 supports both Debian Squeeze and Wheezy. However, since v0.14.10, Synnefo supports only Ganeti >= 2.8. This means that at least the Ganeti nodes of a Synnefo deployment should run on Wheezy.
To upgrade to Synnefo v0.14.10 one needs to upgrade both Synnefo and Ganeti during the same upgrade cycle, so some minimal service downtime is needed. As always, VMs, Networks and Files will remain usable during the upgrade.
Since this is an upgrade to a minor version, no special upgrade operations are needed except from the package upgrades.
First, bring all services (Synnefo and Ganeti) down:
root@astakos-host# /etc/init.d/gunicorn stop
root@cyclades-host# /etc/init.d/gunicorn stop
root@pithos-host# /etc/init.d/gunicorn stop
root@ganeti-master-host# /etc/init.d/ganeti stop
root@ganeti-master-host# /etc/init.d/snf-ganeti-eventd stop
root@ganeti-nodeX-host# /etc/init.d/ganeti stop
root@cyclades-host# /etc/init.d/snf-dispatcher stop
Once, everything is stopped, upgrade Ganeti following the official upgrade notes found here:
In a nutshell:
Install the new Ganeti packages. To be able to use hotplug (which will be part of the official Ganeti 2.10), we recommend using our Ganeti packages with version: snf-ganeti=2.8.2+snapshot1+b64v1+hotplug3+ippoolfix+rapifix+netxen+lockfix2-1~wheezy
root@ganeti-master-host# apt-get install snf-ganeti ganeti-htools ganeti-haskell
root@ganeti-nodeX-host# apt-get install snf-ganeti ganeti-htools ganeti-haskell
Note
Make sure you install all three Ganeti packages to all hosts. Also all packages should have the same version.
Upgrade Ganeti’s configuration (make sure you do all backup and dry-run steps as described in the official guide):
root@ganeti-master-host# /usr/share/ganeti/cfgupgrade
Start Ganeti and re-distribute the configuration to all Ganeti master candidates:
root@ganeti-master-host# /etc/init.d/ganeti start
root@ganeti-nodeX-host# /etc/init.d/ganeti start
root@ganeti-master-host# gnt-cluster redist-conf
root@ganeti-master-host# /etc/init.d/ganeti stop
root@ganeti-nodeX-host# /etc/init.d/ganeti stop
Install the new v0.14.10 packages on all hosts according to your deployment.
Once, everything is installed successfully, start all services (Synnefo and Ganeti):
root@cyclades-host# /etc/init.d/snf-dispatcher start
root@ganeti-master-host# /etc/init.d/snf-ganeti-eventd start
root@ganeti-master-host# /etc/init.d/ganeti start
root@ganeti-nodeX-host# /etc/init.d/ganeti start
root@astakos-host# /etc/init.d/gunicorn start
root@cyclades-host# /etc/init.d/gunicorn start
root@pithos-host# /etc/init.d/gunicorn start
