If you only have one server, you may want to practice constructing a new server and cell entirely from backups. That should tell you how easily you can recover from a disaster scenario, and whether your backups are actually adequate. But that concept isn't really AFS-specific. If you set up more fileservers or database servers (which tends to be a good idea for other reasons anyway), you can move/create 'test' volumes to them and experiment with known failure scenarios. e.g. see what happens when a fileserver or dbserver drops off the network, when garbage is written to /vicep*, or when you pull the power cord or 'kill -9' AFS daemons. You could even set up a separate "test" cell and realm depending on how much effort and resources you want to spend on it. Some sites find such a thing also useful for testing new versions, new functionality, etc. And, of course, you can "be prepared" by purchasing a commercial support contract :) <http://www.openafs.org/support.html>. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
