1. Created a distribute volume with 3 bricks
2. mounted using the command "/opt/glusterfs/3.2.6qa3/sbin/glusterfs --log-level=INFO --xlator-option=dist*.assert-no-child-down=yes --volfile-id=/dist --volfile-server=10.1.11.117 /mnt"
3. cd /mnt
4. killed one of the brick
5. cd /
6. client was automatically unmounted


Marking as verified
