> Key: CLOUDSTACK-6460
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6460
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the default.)
> Components: KVM, Volumes
> Affects Versions: 4.2.0, 4.2.1, 4.3.0, 4.4.0
> Environment: KVM clusters with fiber channel SAN storage, CLVM volumes
> Reporter: Salvatore Sciacco
> Attachments: CLOUDSTACK-6460-darrentang.patch, cloudstack-6460.patch, cloudstack-6460_44.patch
>
>
> ACS version: 4.2.1
> Hypervisors: KVM
> Storage pool type: CLVM
> Since we upgraded from 4.1 to 4.2.1 moving volumes to a different primary storage pool fail. I've enabled debug on the agents side and I think there is a problem with the format type conversion
> Volume on database had format QCOW2
> these are the parameters for the first step (CLVM -> NFS):

> Migration worked before we migrated to 4.2.1.
