+By specifying "device vg" in volume create, a volume capable of exporting block devices(ie Volume Groups (VG)) is created. As of now exporting only VG is supported. While creating block backend volume the "VG" (mentioned in NEW-BRICK) must exist (ie created with vgcreate). VG is exported as a directory and all LVs under that VG will be exported as files. Please refer BD commands section for Block backend related commands
