Description of problem:
=======================
Create Directory from mount point and while creation is in progress (Directory created only on hashed sub-volume), execute lookup from another mount point 

i.e. from one mout point :- 

[root@OVM1 nfs]# mkdir 3

from another mount point:- ls

Directory creation gives error "mkdir: cannot create directory `3': Input/output error" eventhough Directory is created on all up sub-volumes.


Version-Release number :
=========================
3.6.0.24-1.el6rhs.x86_64


How reproducible:
=================
always


Steps to Reproduce:
====================
1. create and mount distributed volume. (mount on multiple client)
2. from one mount point give mkdir and make sure when Directory is create donly on hashed issue lookup

[root@OVM3 ~]# tree /brick*
/brick0
/brick1
/brick2
├── r1
│   ├── 1
│   ├── 2
│   └── 3
├── r2
│   ├── 1
│   └── 2
└── r3
    ├── 1
    └── 2
/brick3

10 directories, 0 files

now lookup should come

3. Directory creation fails with 'I/O error' but Directory is present on all up sub-volume

[root@OVM1 nfs]# mkdir 3
mkdir: cannot create directory `3': Input/output error

[root@OVM3 ~]# tree /brick*
/brick0
/brick1
/brick2
├── r1
│   ├── 1
│   ├── 2
│   └── 3
├── r2
│   ├── 1
│   ├── 2
│   └── 3
└── r3
    ├── 1
    ├── 2
    └── 3
/brick3

12 directories, 0 files



Actual results:
===============
- mkdir fails with error 'mkdir: cannot create directory `3': Input/output error'

Expected results:
=================
- If Directory is created on all upp sub-volumes with same gfid, mkdir should nto give error
