We completed the tests. But there is good news and bad news. The good news is that we were able to shake out a lot of bugs in the no journal case (which have already been submitted upstream). We now can fairly quickly and easily drive a lot of traffic to a system and then cut the power, issue a panic or other event. The bad news is that I was hoping to use open source tools to drive the traffic. The goal would be to allow everyone to reproduce the experiment. We got a little short handed on resources and ended up using Google closed source workloads instead. This was mostly since we were in a rush and able to get the network traffic up in one day with those tools. I was holding back on publishing the results since I was hoping we would be able to generate traffic in a more open manner. But if you are interested in the results anyway then give me or some one on the team a day or two to dig them up. In any case we have powerfail testing as part of our validation and once Jiayingz is satisfied with the patch we will be running those tests. mrubin -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
