Thank you, Milan. Will try these.If you need experiment over a memory device, use either ramdisk, scsi_debug module to it. Another alternative is to create dm-zero device and use plain dm-crypt (not LUKS).create dm-zero device: How do I do this? Sorry, I do not have much expertise in Linux.
E.g. 10TiB "zero" mapped device (pick your name instead of 'z'): dmsetup create z --table "0 $((10*1024*1024*1024*2)) zero" Block device node for this is: /dev/mapper/z See dmsetup(8) and device-mapper target documentation in kernel source, for instance Documentaion/device-mapper/zero.txt. Heinz
