-----------------------------------------------
Summary: Object_Store_Refactor - Snapshots - There is no delta
snapshots being created for subsequent snapshots when multiple snapshots are
taken for root /data volumes.
Key: CLOUDSTACK-2630
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2630
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0
Environment: Build from object store
Reporter: Sangeetha Hariharan
Priority: Blocker
Fix For: 4.2.0
Object_Store_Refactor - Snapshots - There is no delta syncs being created for
subsequent snapshots when multiple snapshots are taken for root /data volumes
Steps to reproduce the problem:
Deploy a Vm with root and data disk.
Take 1 snapshot of root volume.
Do some changes to the root volume like create files.
Take another snapshot of root volume.
Notice that the 2nd snapshot taken is not a delta snapshot.
