Comment 9 Anil Shah 2016-12-20 05:38:53 UTC 
[root@rhs-client46 ~]# gluster v stop gluster_shared_storage
Stopping the shared storage volume(gluster_shared_storage), will affect features like snapshot scheduler, geo-replication and NFS-Ganesha. Do you still want to continue? (y/n) y

volume stop: gluster_shared_storage: success

[root@rhs-client46 ~]# gluster snapshot create snap1 test-volume no-timestamp
snapshot create: success: Snap snap1 created successfully

[root@rhs-client46 ~]# gluster snapshot activate snap1
Snapshot activate: snap1: Snap activated successfully


[root@rhs-client46 ~]# gluster snapshot clone clone2 snap1
snapshot clone: success: Clone clone2 created successfully

[root@rhs-client46 ~]# gluster v start clone2
volume start: clone2: success

Able to create Snapshots, when gluster_shared_storage is down. Bug verified on build glusterfs-3.8.4-9.el7rhgs.x86_64
