* ctdb-packaging: Enable some standard event scripts if none are enabledMartin Schwenke2018-07-111-3/+31
| | | | | | | | | | | | | CTDB needs the legacy/00.ctdb event script to be able to function properly. If this script is not enabled then assume a first-time install or an upgrade to a version that requires events scripts to be enabled via symlinks. In these cases enable this script and other commonly used scripts. Remove links during uninstall (but not during upgrade).

* ctdb-daemon: Change default for tunable NoIPHostOnAllDisabled to 1Martin Schwenke2018-07-1115-371/+38
| | | | | | | | | | | | | | | | | Defaulting to host public IP addresses when all nodes are unhealthy does not obey the principle of least surprise. It has caused much confusion over the years. It often leads to problems when all nodes are unhealthy due to something like a cluster filesystem being unmounted. Change the default value for this tunable as the first step of completely removing this behaviour. Remove tests that set NoIPHostOnAllDisabled=1 and update the expected result for other tests where no nodes are healthy.
