@ustcweizhou Not necessary. The issue affects removal of primary storage DS
where there are snapshot copies. After that the snapshot could remain on
secondary storage.

> h3. Actual behaviour
> If there is snapshot on a data store that is removed, {{listSnapshots}} still
> tries to enumerate it and gives error (in this example data store 2 has been
> removed):
> {code:xml|title=/client/api?command=listSnapshots&isrecursive=true&listall=true|borderStyle=solid}
> <listsnapshotsresponse cloud-stack-version="4.9.1.0-SNAPSHOT">
> <errorcode>530</errorcode>
> <cserrorcode>4250</cserrorcode>
> <errortext>Unable to locate datastore with id 2</errortext>
> </listsnapshotsresponse>
> {code}
> h3. Reproduce error
> This steps can be followed to reproduce issue:
> * Take a snapshot of a volume (this creates a references for primary storage
> and secondary storage in snapshot_store_ref table
> * Simulate retiring primary data storage where snapshot is cached (in this
> example X is a fake data store and Y is snapshot id):
> {{UPDATE `cloud`.`snapshot_store_ref` SET `store_id`='X', `state`="Destroyed"
> WHERE `id`='Y';}}
> * List snapshots
> {{/client/api?command=listSnapshots&isrecursive=true&listall=true}}
