Thanks to Jeff Darcy for that. This patch is a part of the arbiter logic implementation for 3 way AFR details of which can be found at http://review.gluster.org/#/c/9656/ Change-Id: Idbfe4f29ee8e098e0102def8f38b32314316b188 BUG: 1217689 Signed-off-by: Ravishankar N <ravishankar> Reviewed-on: http://review.gluster.org/10479 Tested-by: Gluster Build System <jenkins.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu> Reviewed-by: Atin Mukherjee <amukherj> REVIEW: http://review.gluster.org/10514 (afr: add arbitration support) posted (#1) for review on release-3.7 by Ravishankar N (ravishankar) REVIEW: http://review.gluster.org/10542 (doc: AFR arbiter volume usage) posted (#1) for review on release-3.7 by Ravishankar N (ravishankar) COMMIT: http://review.gluster.org/10514 committed in release-3.7 by Vijay Bellur (vbellur) ------ commit d7c30458c87f1341295f764e1a2a539dc4248ecc Author: Ravishankar N <ravishankar> Date: Wed Apr 15 22:22:08 2015 +0530 afr: add arbitration support Backport of http://review.gluster.org/#/c/10258/ Add logic in afr to work in conjunction with the arbiter xlator when a replica 3 arbiter volume is created. More specifically, this patch: * Enables full locks for afr data transaction for such volumes. * Removes the upfront marking of pending xattrs at the time of pre-op and defer it to post-op. (This is an arbiter independent change and is made for all afr transactions.) * After pre-op stage, check if we can proceed with the fop stage without ending up in split-brain by examining the changelog xattrs. * Unwinds the fop with failure if only one source was available at the time of pre-op and the fop happened to fail on particular source brick. * Skips data self-heal if arbiter brick is the only source available. * Adds the arbiter-count option to the shd graph.
