Sorry for the incremental updates, but I think I figured it out. The 
release you are using 3.7.2, doesn't have the fix. The fix is present in 
the master branch, and the release 3.7 branch of the gluster codebase, 
but was sent a few days after this particular release was rolled out. 
Hence the bug(https://bugzilla.redhat.com/show_bug.cgi?id=1232430) is 
still in MODIFIED state. Once  a new release(3.7.3) is rolled out 
(sometime towards the end of next week), it will contain this fix, this 
particular bug will me moved to ON_QA.
