OK -- but that is the normal case of RBD w/o the need for fancy striping (i.e. no need for the special feature bit). The striping feature is only needed when using stripe counts != 1 and stripe units != object size. When you specify the "--stripe-unit" / "--stripe-count" via the CLI, we just assume you really really want the striping feature bit enabled regardless of whether or not it makes sense (it doesn't in your case above).
