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 process-exists' shows correct information.
|
|
|
|
The implementation is creative about how it gets PIDs for existing and
|
|
non-existing processes.
|
|
|
|
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. On one of the cluster nodes, get the PID of an existing process
|
|
(using ps wax).
|
|
3. Run 'ctdb process-exists <pid>' on the node and verify that the
|
|
correct output is shown.
|
|
4. Run 'ctdb process-exists <pid>' with a pid of a non-existent
|
|
process and verify that the correct output is shown.
|
|
|
|
Expected results:
|
|
|
|
* 'ctdb process-exists' shows the correct output.
