There is a minor correction needed to the setup outlined above, as the enc-loop mapper device is backed by the second loopback device, and the volume group consists of the two devices listed in [ ] :
Mind there are SCSI devices providing 4k block sizes, thus check with 'blockdev --getbsz' to actually run a scenario from 512 --> 4096 bytes block sizes.

LV enc-loop ] enc-loop

VG: LOOP_VG [ /dev/loop0, /dev/mapper/

PV: /dev/loop0 --> /dev/mapper/
( backed by /dev/loop1 )
