========
3.4.0.69rhs-1.el6rhs.x86_64


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


Steps to Reproduce:
===================
1. create, start and mount distributed volume. 
2. create few files inside it

[root@localhost new]# ls -l
total 0
-rw-r--r-- 1 root root 0 Oct 27 12:43 a
-rw-r--r-- 1 root root 0 Oct 27 12:43 b
-rw-r--r-- 1 root root 0 Oct 27 12:43 c
-rw-r--r-- 1 root root 0 Oct 27 12:43 d


3. start renaming files from multiple mount
while true; do cd /mnt/m1/new; mv -f a b; mv -f c d; mv -f b a; mv -f d c; cd / ; done

4. break loop after some time and check files

[root@localhost new]# ls -l
total 0

verify file on backend

[root@localhost new]# ls -l /rhs/brick1/*/new
/rhs/brick1/m1/new:
total 0

/rhs/brick1/m2/new:
total 0
-rw-r--r-- 2 root root 0 Oct 27 13:53 b

/rhs/brick1/m3/new:
total 0

/rhs/brick1/m4/new:
total 0


[root@localhost new]# ls -l /rhs/brick1/m*/new
/rhs/brick1/m1/new:
total 0

/rhs/brick1/m2/new:
total 0

/rhs/brick1/m3/new:
total 0

/rhs/brick1/m4/new:
total 0


Actual results:
===============
file a and b are not present on mount as well as backend

Expected results:
===============
at least one file a or b should present.
