0) deploy any HA cluster of 3 controllers.
Assume we have a node-1 as a primary controller with the rabbit multistate clone resource master running, and
node-2, node-3 as running multistate resource slaves.
1) Move rabbit master resource to node-2
2) wait for ostf ha passed
3) kill the node-2, which should be a rabbit master now
4) wait for ostf ha passed
5) power on node-2
6) wait for it joined the rabbit cluster (wait for ostf ha passed)
7) repeat 1-6
Expected:
A. The rabbitmq cluster assembles from two remaining nodes, having 1 master and 1 slave after the step #4, no longer than in 5 minutes.
B. The rabbitmq cluster assembles from three nodes, having 1 master and 2 slaves after the steps #2, #6, no longer than in 5 minutes.
C. At least one node is always available for AMQP connections and it's queues and messages synced with other nodes, if any available as well. |
