nfs-ganesha-gluster-2.4.1-1.el7rhgs.x86_64
glusterfs-ganesha-3.8.4-5.el7rhgs.x86_64


How reproducible:
Always

Steps to Reproduce:
1.Create ganesha cluster setup
2. create a volume,start it
3. Execute gluster vol reset volname <any vol option>

Actual results:
It resets the ganesha enable option as well and brings ganesha and other
services to stopped state and pcs status shows all nodes stopped.

Expected results:
The volume reset for specific option should only reset taht option and should
not cause changes to ganesha related options and should not bring down the
cluster.
