Description of problem:
=======================
Restarting  glusterd after rebalance is completed, and on checking rebalance status , it shows that rebalance is in progress even though there are no files which are rebalanced


Version-Release number of selected component (if applicable):
============================================================
glusterfs 3.4.0.44.1u2rhs

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


Steps to Reproduce:
===================
1.Create a distribute volume with 3 bricks and start it 

2.Fuse mount the volume and create files 

3.Add bricks and start rebalance 

4.After rebalance is completed , stop and start glusterd

[root@boost d3]# gluster v rebalance vol3 status
                                    Node Rebalanced-files          size       scanned      failures       skipped               status   run time in secs
                               ---------      -----------   -----------   -----------   -----------   -----------         ------------     --------------
                               localhost                0        0Bytes           100             0             0            completed               0.00
                             10.70.34.88                0        0Bytes           100             0             0            completed               0.00
                             10.70.34.86                0        0Bytes           100             0             0            completed               0.00
volume rebalance: vol3: success: 

[root@boost d3]# service glusterd stop
Stopping glusterd:                                         [  OK  ]
[root@boost d3]# service glusterd start
Starting glusterd:                                         [  OK  ]


5. Check rebalance status immediately . Status shows rebalance is 'in progress'. [ Rebalance was NOT STARTED after restarting glusterd and there are no files being rebalanced ]

gluster v rebalance vol3 status
                                    Node Rebalanced-files          size       scanned      failures       skipped               status   run time in secs
                               ---------      -----------   -----------   -----------   -----------   -----------         ------------     --------------
                               localhost                0        0Bytes             0             0             0          in progress               0.00
                             10.70.34.88                0        0Bytes             0             0             0          in progress               0.00
                             10.70.34.86                0        0Bytes           100             0             0            completed               0.00
volume rebalance: vol3: success: 



Actual results:
===============
Rebalance status shows it is in progress after restarting glusterd (no files being rebalanced and no rebalance start command executed)

Expected results:
=================
After restarting glusterd , rebalance status should show the previous rebalance operation completed unless a new add brick or rebalance start is executed .
