Wido den Hollander commented on CLOUDSTACK-4304:
------------------------------------------------
I think this has been resolved in the 4.2 branch.
RBD volumes were marked as "QCOW2" format in the database while they are
actually "RAW".
I resolved this yesterday with CLOUDSTACK-4114
> ceph:nfsfail to attach a volume created from snapshot to same Instance

> By default when we perform create volume form snapshot(which NFS based

> nfs :normal
> RBD :RBD
> 3. select the nfs based compute offering and deployed a VM
> 4.Once it successful,select the root partition and perform snapshot
> 5.once snapshot successful,create a volume from snapshot
> here it internally convering into RAW disk(qcow2 format to Raw format) even
> though snapshot volume is NFS bassed
> 6.once it created,try to attche newly created data disk to same VM createdin

> Actual result:
> attach volume failed with error code 530 "Failed to attach volume:
