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.
