The command 'ctdb restoredb' is used to restore a database across the
whole cluster.
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. Create a persistent test database
3. Add some records to test database
4. Backup database
5. Wipe database and verify the database is empty on all nodes
6. Restore database and make sure all the records are restored
7. Make sure no recovery has been triggered
Expected results:
* Database operations should not cause a recovery
