Chapter 4. Testing


Warning

The following procedure involves deliberately crashing a Compute node. Doing so forces the automated evacuation of instances through Instance HA.

  1. Boot one or more instances on the overcloud before crashing the Compute node hosting the instances in question:

    stack@director $ . overcloudrc
    stack@director $ nova boot --image cirros --flavor 2 test-failover
    stack@director $ nova list --fields name,status,host
  2. Log in to the Compute node hosting the instances you just booted (as in, compute-n):

    stack@director $ . stackrc
    stack@director $ ssh -lheat-admin compute-n
    heat-admin@compute-n $
  3. Crash the node:

    heat-admin@compute-n $ echo c > /proc/sysrq-trigger
  4. After several minutes, verify that these instances restarted on online Compute nodes. To check:

    stack@director $ nova list --fields name,status,host
    stack@director $ nova service-list
