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 it is possible to SSH to a public address after disabling a node.
|
|
|
|
# We SSH to a public IP and check the hostname, disable the node hosting
|
|
# it and then SSH again to confirm that the hostname has changed.
|
|
|
|
# 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. SSH to the selected public address and run hostname.
|
|
# 4. Disable the selected node.
|
|
# 5. SSH to the selected public address again and run hostname.
|
|
|
|
# Expected results:
|
|
|
|
# * When a node is disabled the public address fails over and it is
|
|
# still possible to SSH to the node. The hostname should change.
