Likitha Shetty resolved CLOUDSTACK-8113.
----------------------------------------
Resolution: Fixed
+Root Cause Analysis+
Volume migration /VM migration with storage will fails if volume's path in DB
(volume attached to the VM) doesn't match the volume's actual VMDK path.
When a VM is migrated with storage, all its volume's (entire disk chain) is
migrated to the destination primary storage. In case of linked clones, the ROOT
volume's chain will contain the parent template which is present in primary
storage and the ROOT disk VMDK. Once the VM has been migrate if a volume
snapshot is taken on the volume, it results in the coalesce of the ROOT disk
chain wherein vCenter removes the top of the disk chain. This is because volume
snapshot involves creation and deletion of VM snapshots during which vCenter
coalesces the disk chain. Since vCenter removes the top of the disk chain, ROOT
volumes' path changes. CS updates the volume path of only the volume whose
snapshot is being taken once a volume snapshot has been taken. That is why any
further operations on the volume like migration that depend on the volume's
path will fail for the ROOT volume is the snapshot of a Datadisk is taken.
