------------------------------------------------------
Summary: [KVM] [Zone Wide Primary Storages] migrateVolume is
failing with NPE
Key: CLOUDSTACK-3943
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3943
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Storage Controller
Affects Versions: 4.2.0
Reporter: venkata swamybabu budumuru
Priority: Critical
Fix For: 4.2.0
Steps to reproduce :
1. Have at least one advanced zone with KVM cluster (2 kvm hosts)
2. Make sure that the setup has at least 2 zone wide primary storages. (from
ex: zwps1, zwps2)
3. Deploy a VM as admin
4. Create a datadisk of size 5 GB as admin on zwps1
5. attach the above datadisk to the VM in step 3
6. detach the data disk
7. initiate migrateVolume command for the above datadisk to zwps2
