I'd probably be interested, but naive question.. how would this be different from the Ceph Days? On Wed, Sep 25, 2013 at 10:53 AM, Loic Dachary l...@dachary.org wrote: Hi Eric Patrick, Yesterday morning Eric suggested that organizing a ceph user meetup would be great and proposed his help

Hi Andreas, It looks like this code would be useful as a standalone program instead of being integrated within unit tests. There are a few support program of that kind. The unit tests are probably not the best place for benchmarks. What do you think ? Cheers Note: got the updated file ;-)

Applied this to the ceph-client.git master branch. I'll send this upstream shortly after it gets some testing and/or any other fixes pile up. Thanks! sage On Wed, 25 Sep 2013, Milosz Tanski wrote: In some cases I'm on my ceph client cluster I'm seeing hunk kernel tasks in the invalidate
