+++ This bug was initially created as a clone of Bug #1272460 +++ Description of problem: Reported by Manikandan Selvaganesh <mselvaga> How reproducible: Always Steps to Reproduce: 1.Create a 1x2 replica and mount it 2. Kill a brick 3. From the mount ,dd if=/dev/zero of=file bs=1024 count=40240 4. restart the brick, trigger heal 5. check disk usage (du -sh) of the bricks. Actual results: disk usage discrepancy Expected results: disk usage must be nearly identical. --- Additional comment from Vijay Bellur on 2015-10-16 08:59:47 EDT --- REVIEW: http://review.gluster.org/12371 (afr: write zeros to sink for non-sparse files) posted (#1) for review on master by Ravishankar N (ravishankar) --- Additional comment from Vijay Bellur on 2015-10-19 07:06:40 EDT --- REVIEW: http://review.gluster.org/12371 (afr: write zeros to sink for non-sparse files) posted (#2) for review on master by Ravishankar N (ravishankar) --- Additional comment from Vijay Bellur on 2015-10-21 12:40:51 EDT --- REVIEW: http://review.gluster.org/12371 (afr: write zeros to sink for non-sparse files) posted (#3) for review on master by Ravishankar N (ravishankar) --- Additional comment from Vijay Bellur on 2015-10-27 06:58:12 EDT --- REVIEW: http://review.gluster.org/12371 (afr: write zeros to sink for non-sparse files) posted (#4) for review on master by Ravishankar N (ravishankar) --- Additional comment from Vijay Bellur on 2015-10-27 20:44:24 EDT --- REVIEW: http://review.gluster.org/12371 (afr: write zeros to sink for non-sparse files) posted (#5) for review on master by Ravishankar N (ravishankar)

COMMIT: http://review.gluster.org/12436 committed in release-3.7 by Pranith Kumar Karampuri (pkarampu) ------ commit 50646435b4076cfb30d7ebabf2d688f91c957cec Author: Ravishankar N <ravishankar> Date: Wed Oct 21 21:05:46 2015 +0530 afr: write zeros to sink for non-sparse files Backport of http://review.gluster.org/#/c/12371/ Problem: If a file is created with zeroes ('dd', 'fallocate' etc.) when a brick is down, the self-heal does not write the zeroes to the sink after it comes up. Consequenty, there is a mismatch in disk-usage amongst the bricks of the replica. Fix: If we definitely know that the file is not sparse, then write the zeroes to the sink even if the checksums match.
