The main change is to source cluster.bash instead of integration.bash. While touching the preamble, the following additional changes are also made: * Drop test_info() definition and replace it with a comment The use of test_info() is pointless. * Drop call to ctdb_test_check_real_cluster() cluster.bash now does this. * Drop call to cluster_is_healthy() This is a holdover from when the previous test would restart daemons to get things ready for a test. There was also a bug where going into recovery during the restart would sometimes cause the cluster to become unhealthy. If we really need something like this then we can add it to ctdb_test_init().

# Verify that a gratuitous ARP is sent when a node is failed out.
|
|
|
|
# We ping a public IP and lookup the MAC address in the ARP table. We
|
|
# then disable the node and check the ARP table again - the MAC address
|
|
# should have changed. This test does NOT test connectivity after the
|
|
# failover.
|
|
|
|
# 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. Remove any entries for the chosen address from the ARP table.
|
|
# 4. Send a single ping request packet to the selected public address.
|
|
# 5. Determine the MAC address corresponding to the public address by
|
|
# checking the ARP table.
|
|
# 6. Disable the selected node.
|
|
# 7. Check the ARP table and check the MAC associated with the public
|
|
# address.
|
|
|
|
# Expected results:
|
|
|
|
# * When a node is disabled the MAC address associated with public
|
|
# addresses on that node should change.
