afr: add arbitration support
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. 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: I9603db9d04de5626eb2f4d8d959ef5b46113561d BUG: 1199985 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/10258 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
