Glitches during restarts of the CTDB cluster have been causing some tests to fail. This is because restarts are initiated in the body of many tests. This adds a simple function ctdb_restart_when_done, which schedules a restart using an existing hook in the test exit code. This function is now used in tests that need to restart CTDB.

Verify that an IP address can be added to a node using 'ctdb addip'.
|
|
|
|
This test goes to some trouble to figure out which IP address to add
|
|
but assumes a 24-bit subnet mask. It does not handle IPv6. It does
|
|
not do any network level checks that the new IP address is reachable
|
|
but simply trusts 'ctdb ip' that the address has been added. There is
|
|
also an extra prerequisite that the node being added to already has
|
|
public addresses - this is difficult to avoid if the extra address is
|
|
to be sensibly chosen.
|
|
|
|
Prerequisites:
|
|
|
|
* An active CTDB cluster with at least 2 active nodes.
|
|
|
|
Steps:
|
|
|
|
1. Verify that the status on all of the ctdb nodes is 'OK'.
|
|
2. Use 'ctdb ip' on one of the nodes to list the IP addresses being
|
|
served.
|
|
3. Add an additional public address to be served by the node, using
|
|
'ctdb addip'.
|
|
4. Verify that this IP address has been added to the list of IP
|
|
addresses being served by the node, using the 'ctdb ip' command.
|
|
|
|
Expected results:
|
|
|
|
* 'ctdb ip' adds an IP address to the list of public IP addresses
|
|
being served by a node.
