Many tests currently do this sort of thing: onnode 0 $CTDB_TEST_WRAPPER wait_until_node_has_status 1 disconnected In fact, they all use exactly the same "onnode 0 $CTDB_TEST_WRAPPER" idiom. This is both repetitious and dangerous, since node 0 might be shutdown during a test. Instead, we push "onnode any $CTDB_TEST_WRAPPER" (which selects a connected node) into wait_until_node_has_status() and just call that function directly in tests, like this: wait_until_node_has_status 1 disconnected Signed-off-by: Martin Schwenke <martin@meltin.net> (This used to be ctdb commit a2aaef03d4d6bbd4b42f50f732254935d4d3469c)

Verify 'ctdb thaw' works correctly.
|
|
|
|
This is a superficial test that simply checks that 'ctdb statistics'
|
|
reports the node becomes unfrozen. No checks are done to ensure that
|
|
client access to databases is unblocked.
|
|
|
|
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 freeze -n <node>' to freeze the databases on one of the
|
|
nodes.
|
|
3. Run 'ctdb statistics' to verify that 'frozen' has the value '1' on
|
|
the node.
|
|
4, Now run 'ctdb thaw -n <node>' on the same node.
|
|
5. Run 'ctdb statistics' to verify that 'frozen' once again has the
|
|
value '0' on the node.
|
|
|
|
|
|
Expected results:
|
|
|
|
* 'ctdb thaw' causes a node to 'thaw' and the status change can be
|
|
seem via 'ctdb statistics'.
