cluster_is_healthy() is now run locally in tests and internally causes _cluster_is_healthy() to be run on node 0. When it detects that the cluster is unhealthy and $ctdb_test_restart_scheduled is not true, debug information is printed. This replaces the previous use of $CTDB_TEST_CLEANING_UP. To avoid spurious debug on expected restarts, added scheduled restarts to several tests.

Verify that 'ctdb statisticsreset' works as expected.
|
|
|
|
This is pretty superficial. It just checks that a few particular
|
|
items reduce.
|
|
|
|
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. Run 'ctdb statisticsreset' on all nodes and verify that it executes
|
|
successfully.
|
|
|
|
Expected results:
|
|
|
|
* 'ctdb statisticsreset' executes successfully.
