Looks to be reproducable.Does this happen with rc6 ?I haven't tried. All I'm doing is running some benchmarks to get numbers for a talk I'm giving about improvements in XFS metadata scalability, so I wanted to update my last set of numbers from 2.6.39. As it was, these benchmarks also failed on btrfs with oopsen and corruptions back in 2.6.39 time frame. e.g. same VM, same test, different crashes, similar slowdowns as reported here: http://comments.gmane.org/gmane.comp.file-systems.btrfs/11062 Given that there is now a history of this simple test uncovering problems, perhaps this is a test that should be run more regularly by btrfs developers?Unfortunately, this one works for me. I'll try it again and see if I can push harder. If not, I'll see if I can trade beer for some diagnostic runs.
Aha, if I try it just on the ssd instead of on my full array it triggers at 88M files. Great. -chris
