So command should be

Use this 'skip' number of the 'seek' number later.

Thanks, Neil, now it makes more sense.
I tried to create new linear device, but mdadm is complaining about
data-offset:
# mdadm -C /dev/md4 -l linear -n 2 --rounding=1M -e 1.0 --data-offset=0
/dev/md2 /dev/md3
mdadm: invalid data-offset: 0
I'm using Debian 8.8 if it makes any difference.
# mdadm -V
mdadm - v3.3.2 - 21st August 2014
What could be the problem?

Veljko
