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.
*** Bug 905747 has been marked as a duplicate of this bug. ***
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.
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.
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.
