Description of problem: 
When you set the tunable nfs.export-volumes to, it affects all volumes, and is displayed under "Options Reconfigured" in a gluster volume info. But when creating a new volume, it does not show up under "Options Reconfigured" despite being active (i.e. the newly created volume is not NFS-exported).


Version-Release number of selected component (if applicable): 2.0 Update 3


How reproducible: Reproducible


Steps to Reproduce:
1. 
[root@sarhs02 swift]# gluster volume set rhev_vol nfs.export-volumes off

2.
[root@sarhs02 swift]# gluster volume info rhev_vol

Volume Name: rhev_vol
Type: Replicate
Volume ID: db3b9f74-7122-471b-8d91-42223fc33c72
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: sarhs01:/brick_rhev
Brick2: sarhs03:/brick_rhev
Options Reconfigured:
nfs.export-dir: /lib-exports,/lib-ovirt-engine,/lib-pgsql,/share-jasperreports-server-pro,/share-ovirt-engine,/share-ovirt-engine-dwh,/share-ovirt-engine-reports
nfs.export-volumes: off

3. 
[root@sarhs02 swift]# gluster volume create testvol replica 2 sarhs02:/brick1 sarhs04:/brick1
Creation of volume testvol has been successful. Please start the volume to access data.
[root@sarhs02 swift]# gluster volume start testvol
Starting volume testvol has been successful
[root@sarhs02 swift]# 
 
4. 
[root@client1 Demo_Scripts]# showmount -e sarhs02
Export list for sarhs02:
/rhev_vol/lib-exports                    *
/rhev_vol/lib-ovirt-engine               *
/rhev_vol/lib-pgsql                      *

Actual results:
[root@sarhs02 swift]# gluster volume info testvol

Volume Name: testvol
Type: Replicate
Volume ID: 09cb994d-06db-4b8a-98ae-c06e043686c9
