--- Comment #2 from Kaushal <kaushal at redhat.com> ---
Here's a summary of the bug description and analysis.

Heketi sometimes fails to delete the underlying LVs that formed the bricks,
when it deletes a volume. This happens because the multiplexed brick process,
doesnot correctly stop the brick graph, and leaves open a few files on the
brick filesystem. This prevents the brick filesystem from being unmounted, and
the LV from being destroyed.

The open files in question, as possibly of the CTR xlator.
