Those are great, but they're about testing the zfs software. There's a small amount of overlap, in that these injections include trying to simulate the hoped-for system response (e.g, EIO) to various physical scenarios, so it's worth looking at for scenario suggestions.
However, for most of us, we generally rely on Sun's (generally acknowledged as excellent) testing of the software stack. I suspect the OP is more interested in verifying on his own hardware, that physical events and problems will be connected to the software fault injection test scenarios. The rest of us running on random commodity hardware have largely the same interest, because Sun hasn't qualified the hardware parts of the stack as well. We've taken on that responsibility ourselves (both individually, and as a community by sharing findings). For example, for the various kinds of failures that might happen: * Does my particular drive/controller/chipset/bios/etc combination notice the problem and result in the appropriate error from the driver upwards? * How quickly does it notice? Do I have to wait for some long timeout or other retry cycle, and is that a problem for my usage? * Does the rest of the system keep working to allow zfs to recover/react, or is there some kind of follow-on failure (bus hangs/resets, etc) that will have wider impact? Yanking disk controller and/or power cables is an easy and obvious test. Testing scenarios that involve things like disk firmware behaviour in response to bad reads is harder - though apparently yelling at them might be worthwhile :-) Finding ways to dial up the load up your psu (or drop voltage/limit current to a specific device with an inline filter) might be an idea, since overloaded power supplies seem to be implicated in various people's reports of trouble. Finding ways to generate EMF or "cosmic rays" to induce other kinds of failure is left as an exercise. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
