--- Comment #10 from Shekhar Berry <shberry at redhat.com> ---
Krutika,

Thanks for looking into the bug.

Here are couple of my comments:

1) did you invoke the fio command when your current working directory was the
glusterfs mount point itself?

No, I am using pbench_fio for my testing and it stores run logs under
/var/lib/pbench-agent. Just FYI, I am not invoking pbench_fio from gluster
mount point itself :)

2) I redid the test with performance.open-behind: off and
performance.strict-o-direct: on option. The results are no different in my
setup.I am still seeing full cache utilization. 

I have not captured strace under this setting. I can capture and share that
with you if required.
