Subject: RAID0 as a member of RAID6

Hello,
In the process of upgrading my RAID array(s), I got to a situation where I use
a RAID0 of two 1TB disks as a member in RAID6 made mostly of 2TB disks.
Since I use a 64KB chunk size on the RAID6, I thought that for performance
it'd be better to also use a 64KB chunk in the RAID0.
However:
Is there anything special that needs to be done, to ensure that the 64K chunks
of the top-level array align right into the lower-level (RAID0) chunks one to
one, and without any kind of a shift?
The superblock versions are 1.2 on both RAID6 and RAID0.

With respect,
Roman
