Dear Kshitij, we have a version of OrangeFS which is instrumented with HDTrace, there you can record detailed information about activity of statemachines and I/O. For a description see the thesis: http://wr.informatik.uni-hamburg.de/_media/research:theses:Tien%20Duc%20Tien_Tracing%20Internal%20Behavior%20in%20PVFS.pdf
The code is available in our redmine (here is a link to the wiki): http://redmine.wr.informatik.uni-hamburg.de/projects/piosimhd/wiki I consider the tracing implemented in PVFS as rather robust, since it is our second implementation with PVFS_hints. However, you might encounter some issues with the build system. If you want to try it and you need help, just ask.
