--- Comment #1 from Krutika Dhananjay <kdhananj at redhat.com> ---
All is not well in the compound fops world. I wrote and ran the following
simple test on master:

<script>

  0 #!/bin/bash                                                    
  1 . $(dirname $0)/../../include.rc
  2 . $(dirname $0)/../../volume.rc
  3
  4 cleanup
  5
  6 TEST glusterd
  7 TEST pidof glusterd
  8 TEST $CLI volume create $V0 replica 3 $H0:$B0/${V0}{0,1,2}
  9 TEST $CLI volume start $V0
 10 TEST $GFS --volfile-id=$V0 --volfile-server=$H0 $M0
 11
 12 TEST dd if=/dev/urandom of=$M0/file bs=1024 count=10 2>/dev/null
 13 md5sum_file=$(md5sum $M0/file | awk '{print $1}')
 14
 15 TEST $CLI volume set $V0 cluster.use-compound-fops on
 16
 17 TEST dd if=$M0/file of=$M0/file-copy bs=1024 count=10 2>/dev/null
 18
 19 EXPECT_WITHIN $UMOUNT_TIMEOUT "Y" force_umount $M0
 20 TEST $GFS --volfile-id=$V0 --volfile-server=$H0 $M0
 21
 22 EXPECT "$md5sum_file" echo `md5sum $M0/file-copy | awk '{print $1}'`
 23
 24 EXPECT_WITHIN $UMOUNT_TIMEOUT "Y" force_umount $M0
 25 TEST $CLI volume stop $V0
 26 TEST $CLI volume delete $V0
 27
 28 cleanup

</script>


The md5sum comparison at line 22 fails. The script runs fine when I "comment
out" line 15, implying the bug is in compound fops.

Will post my findings after the issue is RC'd.
