Upgrade to Synnefo v0.14.2

The upgrade from v0.14 to v0.14.2 consists in three steps:

1. Bring down services and backup databases.
2. Upgrade packages and migrate Pithos database.
3. Bring up all services.

1. Bring web services down, backup databases

1. All web services must be brought down so that the database maintains a predictable and consistent state during the migration process:

   $ service gunicorn stop
   $ service snf-dispatcher stop
   $ service snf-ganeti-eventd stop

2. Backup databases for recovery to a pre-migration state.

3. Keep the database servers running during the migration process

2. Upgrade Synnefo and configure settings

2.1 Install the new versions of packages

astakos.host$ apt-get install \
                        python-objpool \
                        snf-common \
                        python-astakosclient \
                        snf-django-lib \
                        snf-webproject \
                        snf-branding \
                        snf-astakos-app

cyclades.host$ apt-get install \
                        python-objpool \
                        snf-common \
                        python-astakosclient \
                        snf-django-lib \
                        snf-webproject \
                        snf-branding \
                        snf-pithos-backend \
                        snf-cyclades-app

pithos.host$ apt-get install \
                        python-objpool \
                        snf-common \
                        python-astakosclient \
                        snf-django-lib \
                        snf-webproject \
                        snf-branding \
                        snf-pithos-backend \
                        snf-pithos-app \
                        snf-pithos-webclient

ganeti.node$ apt-get install \
                        python-objpool \
                        snf-common \
                        snf-cyclades-gtools \
                        snf-pithos-backend

Note

Make sure `snf-webproject’ has the same version with snf-common

2.2 Sync and migrate the database

pithos-host$ pithos-migrate upgrade head

5. Bring all services up

After the upgrade is finished, we bring up all services:

astakos.host  # service gunicorn start
cyclades.host # service gunicorn start
pithos.host   # service gunicorn start

cyclades.host # service snf-dispatcher start
