For RAID1, no. For RAID0 and RAID5, potentially.

Have you read the sections about sunit and swidth?
In general mkfs.xfs will do the right thing. As the man page states,
when you run mkfs on an LVM or MD device it will automagically extract
the stripe unit and stripe width.
If you have a hardware RAID device, however, you'll have to specify
these parameters manually to match the configuration of your device.
