From 6f08b9f2b006a4eafaa176cfd792038eed7f6c98 Mon Sep 17 00:00:00 2001 From: Ravishankar N Date: Wed, 25 May 2016 21:18:19 +0530 Subject: afr: Automagic unsplit-brain by [ctime|mtime|size|majority] Backport of http://review.gluster.org/#/c/14026/ Introduce cluster.favorite-child-policy which when enabled with [ctime|mtime|size|majority], automatically heals files that are in split-brian. The majority policy will not pick a source if there is no majority. The other three policies pick the first brick with a valid reply and non-zero ctime/mtime/size as source.
