One serializer created volumes and read them: size was GiB in a request and bytes in an answer, the same field in the schema. A client that sent back a size it read asked for a volume 2**30 times as large. A new volume is CreateVolumeSerializer (size in GiB); a volume read is VolumeSerializer (allocation and size in bytes), and the schema says so, as for the pools' size and free space.
