I do not understand why creating a linear device and then trying to
create another linear device on top of it fails.
1. Creating a linear device over loop1:
===========================
dmsetup create linear_loop1 /tmp/linear_loop1
cat /tmp/linear_loop1
0 1000 linear /dev/loop1 0
2. Then creating another linear device over this linear device:
=============================================
dmsetup create linear_loop2 /tmp/linear_loop2
device-mapper: reload ioctl failed: Invalid argument
Command failed
cat /tmp/klinear_loop2
0 1000 linear /dev/linear_loop1 0
Could you please explain what am I doing wrong?
