If it is a "striped" logical volume it will do that, but since you are creating the LVM on ONE PV namely the md device itself there will be no way for the LVM to stripe it. Of course you could create two MDs and create a LVM stripe acroos those too, but I do not think there is any benefit in that.

Kind regards,
