I meant to create a storage on top of several nodes one needs to have device mapper or something like that on top of NBD itself. To further export resulted device one needs another userspace NDB application and so on. DST simplifies that greatly. DST original code worked as device mapper plugin too, but its two additional allocations (io and clone) per block request ended up for me as a show stopper. -- Evgeniy Polyakov - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
