This is both striping via 2 different, supported device-mapper
targets, 'striped' and 'raid'
('striped' is an older, separate target and 'raid0' is supported
by the 'raid' target which
also supports raid1/raid4/raid5/raid6 and raid10).
The algorithm to distribute data on the stripes is the same for
both striped and raid0
and they can be converted into each other running 'lvconvert
--type striped|raid0 $LV'
since raid target version 1.7.0 / lvm2 version 2.02.155.
See lvmraid(7) for insight into the RAID support in lvm including
the aforementioned
and many more conversions from and to RAID and between RAID levels
and layouts..
