I would like to attend filesystem track in the LSF/MM this year. Other than the obvious Lustre related stuff (ie hearing from Christoph how bad Lustre is and what other parts of it we need to remove), I can share hopefully useful testing methods we came up with in our group that more people can benefit from apparently, as evidenced by some interest from NFS people due to a bunch of problems I was able to uncover. I suspect other networking filesystems would benefit here. I also see there's potentially going to be a caching discussion that sounds pretty relevant to Lustre too. This probably would go hand-in-hand with a somewhat recent discusison with Al Viro about potentially redoing "unmount the subtrees on dentry invalidation" that appears to be overly aggressive now. A container support from filesystems is also very relevant to us since Lustre is used more and more in such settings. Bye, Oleg
