* Use "#!/usr/bin/env bash" for improved portability * Drop test_info() definition and replace it with a comment The use of test_info() is pointless. * Drop call to cluster_is_healthy() This is a holdover from when the previous test would restart daemons to get things ready for a test. There was also a bug where going into recovery during the restart would sometimes cause the cluster to become unhealthy. If we really need something like this then we can add it to ctdb_test_init(). * Make order of preamble consistent Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>
