Whether flush-behind is enabled or not, close() will guarantee all
previous write()s on that fd have been acknowledged by server.
I'm wondering if it is because of attribute cache. Maybe attribute cache (either in fuse or gluster, don't know yet) is not getting invalidated for some reason. Try each of the following and check if any of them make the test work right:
#1 mount glusterfs with --attribute-cache=0
#2 disable stat prefetch with : gluster volume set $name performance.stat-prefetch off
That should help diagnose the problem further.
Thanks
