Sangeetha Hariharan closed CLOUDSTACK-5283.
-------------------------------------------
Currently , when there are issues when backing up the snapshot on secondary ,
CS sets the state of snapshots to "Error" state as part of bug
-CLOUDSTACK-5446.
For such snapshots , we have only 1 primary entry and no image entry in
snapshot_store_ref table.

We are able to list snapshots when we have snapshots in "Error" state:

> Not able to list snapshots when few snapshots are in "CreatedOnPrimary" state.
> Deploy 10 Vms in each of the hosts , so we start with 20 Vms.
> We will be constantly writing to the ROOT volume ( print timestamp every 1
> minute).
> Start concurrent snapshots for ROOT volumes for all the Vms by creating
> "Hourly" snapshot policy at the same time.
> Some of the snapshot creation fails , leaving behind Vms in
> "CreatedOnPrimary" state.
> When listing snapshot , we see the following error message:
