Gluster users - Nov 2015 - 'No data available' at clients, brick xattr ops errors on small I/O -- XFS stripe issue or repeat bug?

Update:  I've tried a second cluster with AFAIK identical backing storage
configuration from the LUNs up, identical gluster/xfsprogs/kernel on the
servers, identical volume setup, and identical kernel/gluster on the clients. 
The reproducer does not fail on the new system.  So far I can't find any
delta between the two clusters' setup other than the brick count (28 bricks
across 8 servers on the failing one, 14 bricks across 4 servers on the new one).

Looks like the errors occur only when the gfid-to-path translation [volume
option] is on.  Is anyone else seeing this?  Anyone using 3.6.6-1 with
XFS-formatted bricks?
