#!/bin/bash

# Verify that it is possible to ping a public address after disabling a node.

# We ping a public IP, disable the node hosting it and then ping the
# public IP again.

# Prerequisites:

# * An active CTDB cluster with at least 2 nodes with public addresses.

# * Test must be run on a real or virtual cluster rather than against
#   local daemons.

# * Test must not be run from a cluster node.

# Steps:

# 1. Verify that the cluster is healthy.
# 2. Select a public address and its corresponding node.
# 3. Send a single ping request packet to the selected public address.
# 4. Disable the selected node.
# 5. Send another single ping request packet to the selected public address.

# Expected results:

# * When a node is disabled the public address fails over and the
#   address is still pingable.
