Nope, I've got an identical behaviour if the array is created by mdadm (v3.3).

I initially created the array with dmraid because it claims to support
ISW format whereas mdadm supports IMSM. I wanted to be sure that ISW
format was also supported by mdadm if the 2 formats were different.

As you can see, I'm confused about ISW vs IMSM.

Are those 2 formats the same thing ?

Thanks.
