Upgrading a cluster

Here are the steps for upgrading a cluster, i.e. two XiVO with High Availability (HA):

  1. On the master : deactivate the database replication by commenting the cron in /etc/cron.d/xivo-ha-master

  2. On the slave, deactivate the xivo-check-master-status script cronjob by commenting the line in /etc/cron.d/xivo-ha-slave

  3. On the slave, start the upgrade:

    xivo-slave:~$ xivo-upgrade
  4. When the slave has finished, start the upgrade on the master:

    xivo-master:~$ xivo-upgrade
  5. When done, launch the database replication manually:

    xivo-master:~$ xivo-master-slave-db-replication <slave ip>
  6. Reactivate the cronjobs (see steps 1 and 2)
