Description of problem: Currently even if a single replica pair goes down, there will be fresh lookups for all files and directories thought there is no layout changes. Hence DHT must avoid fresh lookups when bricks go down. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Create a 2x2 dist-rep volume, mount the volume and create few directories. 2. Bring one the replica pair down. 3. Perform lookup on the directories Actual results: Fresh lookups on all the directories Expected results: Fresh lookup must be avoided, and read xattr from the other pair Additional info:

COMMIT: http://review.gluster.org/12573 committed in master by Jeff Darcy (jdarcy) ------ commit 3f0c70f2d56743707699f6a5b62a1c2c2d5c6f85 Author: Sakshi Bansal <sabansal> Date: Thu Nov 12 12:28:53 2015 +0530 afr: replica pair going offline does not require CHILD_MODIFIED event As a part of CHILD_MODIFIED event DHT forgets the current layout and performs fresh lookup. However this is not required when a replica pair goes offline as the xattrs can be read from other replica pairs. Hence setting different event to handle replica pair going down.
