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
