Fixed In Version: glusterfs-3.6.0.16-1.el6
Doc Type: Enhancement
Doc Text:
The readdir-ahead translator will be enabled by default on newly created volumes in RHS-3.0. This will improve readdir performance for the new volumes. NOTE: readdir-ahead is not compatible with RHS-2.1, so new volumes created with RHS-3.0 cannot be used with RHS-2.1 clients until readdir-ahead is disabled.

Description Kaushal 2014-05-12 07:11:45 UTC 
Readdir ahead should be enabled by default on newly created rhs-3.0 volumes when cluster op-version supports it. For already existing volumes, readdir-ahead will still need to be enabled manually.
Comment 2 Kaushal 2014-05-13 05:26:30 UTC 
The framework needed for this change has been posted for review upstream at http://review.gluster.org/7734
