Description

On storage migration from NFS to Ceph ACS seems to use the secondary storage to temporary store the block device on converting from qcow2 to raw. There seems to be no check on the available space on the secondary storage. If the migrated volume is bigger than the free space on secondary volume the migration will start and fail as soon as the secondary storage got completely filled. After the error message the file copied so far still exists. The usage on the secondary storage stays at 100%.
