Basically I'm asking, is it possible to write a wrapper around DRBD, without making any change to DRBD. DRBD currently doing some operations to mirror data to one secondary node. Now this wrapper function should force it to repeat the same function n times., so that n nodes have mirrored data. Is it possible?
