This bug is not seen in current master branch (which will get branched as RHS 2.1.0 soon). To consider it for fixing, want to make sure this bug still exists in RHS servers. If not reproduced, would like to close this.

Comment 4 shylesh 2013-08-23 17:00:18 UTC
verified on 3.4.0.22rhs-2.el6rhs.x86_64. 
No error message appears upon executing above said steps and I/O will not fail.
