edison su resolved CLOUDSTACK-4008.
-----------------------------------
Resolution: Fixed
> any operation on a snapshot of a delete volume is failing
> ---------------------------------------------------------
>
> Key: CLOUDSTACK-4008
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-4008
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Snapshot
> Affects Versions: 4.2.0
> Environment: KVM
> Reporter: Srikanteswararao Talluri
> Assignee: edison su
> Priority: Blocker
> Fix For: 4.2.0
>
>
> Steps to reproduce:
> ==============
> 1. create a volume and attach it to a VM.
> 2. take some snapshots(say 3 snapshots) of the volume
> 3. detach and delete the volume created in step1.
> 4. try to delete one of the snapshot created in step 2.( results in NPE)
> 5. try to create a template from the snapshot created in step2 ( this is
> causing NPE)
> Observation: it is causing NPE but deleting the db entry.
