Description of problem:
=======================

gluster volume reset is used to "reset all the reconfigured options" and USS is
one of them. But snapd process continues to be online 

[root at inception ~]# gluster v i vol_test | grep uss
features.uss: on
[root at inception ~]# ps -eaf | grep snapd
root      4182     1  0 15:10 ?        00:00:00 /usr/sbin/glusterfsd -s
localhost --volfile-id snapd/vol_test -p
/var/lib/glusterd/vols/vol_test/run/vol_test-snapd.pid -l
/var/log/glusterfs/snaps/vol_test/snapd.log --brick-name snapd-vol_test -S
/var/run/acfb4e617ee26303307f24cfb63c442e.socket --brick-port 49158
--xlator-option vol_test-server.listen-port=49158
root      4228  4111  0 15:10 pts/0    00:00:00 grep snapd
[root at inception ~]# gluster v reset vol_test
volume reset: success: reset volume successful
[root at inception ~]# gluster v i vol_test | grep uss
[root at inception ~]# ps -eaf | grep snapd
root      4182     1  0 15:10 ?        00:00:00 /usr/sbin/glusterfsd -s
localhost --volfile-id snapd/vol_test -p
/var/lib/glusterd/vols/vol_test/run/vol_test-snapd.pid -l

root      4274  4111  0 15:11 pts/0    00:00:00 grep snapd
[root at inception ~]# 

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

glusterfs-3.6.0.40-1.el6rhs.x86_64

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

always

Steps to Reproduce:
===================
1. Create 4 node cluster
2. Create and start a volume
3. Enable USS, confirm snapd process is started on all node
4. Check gluster v i vol-name, uss should be enabled
5. gluster v status should show snapshot-daemon online
6. Reset the volume using "gluster volume reset <vol-name>"
7. Check gluster v i vol-name, uss should not be listed
8. gluster v status should not show snapshot-daemon
9. check snapd process using "ps -eaf | grep snapd" on all nodes

Actual results:
===============
snapd process is online

Expected results:
