--- Comment #8 from Bhaskarakiran <byarlaga at redhat.com> ---
To check this behaviour i executed status and commit commands one after another
without any delay. I again tried this on 3.7.5-6 build and did see the same
behaviour.

If files with data are found on the brick path, copy them via a gluster mount
point before re-purposing the removed brick.
