Linux Clusters, Complexity, and HA

,----[ Quote ]
| Continuing to look at some of the useful things one needs to know when going
| production with Linux. Applies to any other OS too in most ways, but examples
| are all from our Linux deployments, specifically our first year on our Linux
| based NAS.
|
| [...]
|
| The takeaway from all this then: Clusters do not, in and of themselves make
| everything magically more HA. You have to start with the best of breed in
| cluster software, but you also have to know the cluster environment, and test
| it seven ways from yesterday to be sure that in failure mode it is actually
| doing what you think it should be doing. This ties back to something I said
| last post. To paraphrase: There is no substitute for knowing what you are
| doing. Linux is not magic. Clustering is not magic. All the magic comes from
| your people. Your business is only as good as your process: Process designed
| by people who do not know what they are doing will land you in a world of
| hurt.
