Srikanteswararao Talluri created CLOUDSTACK-4008:
----------------------------------------------------
Summary: deleting 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
Priority: Critical
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.
Observation: it is causing NPE but deleting the db entry.
