Upgrade Cluster

Before beginning the upgrade check that:

  • There are no none Roaring Penguin repositories listed.

You should upgrade your CanIt cluster by:

  1. Stop CanIt on all machines:
    /etc/init.d/canit-system stop-gracefully
  2. Upgrade CanIt on the primary database:
    upgrade-canit-appliance
  3. Upgrade CanIt on the remaining machines in any order, or simultaneously.
  4. After running all the upgrades, starting with the database, run:
    /etc/init.d/canit-system start

Note that the "Upgrading Database" part may appear to "hang" for a bit because it doesn't print anything; it's not hung, it's just working without printing anything, so do NOT interrupt it.
