+++ This bug was initially created as a clone of Bug #1221957 +++

GlusterFS 3.7.0 has marked data-tiering as an 'experimental' feature. Basic
functionality for data-tiering is available, but with many restrictions and
known issues.

This bug tracks the improvements made to tiering. Bug reports to improve
tiering in the 3.7 release should have 'glusterfs-tiering-supportability' in
the 'blocks' field.

The required changes to fix this bug have not made it into glusterfs-3.7.1.
This bug is now getting tracked for glusterfs-3.7.2.

--- Additional comment from Niels de Vos on 2015-06-20 06:08:21 EDT ---

Unfortunately glusterfs-3.7.2 did not contain a code change that was associated
with this bug report. This bug is now proposed to be a blocker for
glusterfs-3.7.3.

--- Additional comment from Kaushal on 2015-07-30 09:17:47 EDT ---

This bug could not be fixed in time for glusterfs-3.7.3. This is now being
tracked for being fixed in glusterfs-3.7.4.
