In one embodiment, a method of coordinating data recovery in a storage stack with a hierarchy of layers includes, upon an input/output (I/O) request from a layer of the stack, issuing a help response to recover the data from a higher layer in hierarchy order. The method further includes processing the help response, at the higher layer, by issuing a return code of success or further help response to an even higher layer.
