Actually, I can see that working ... but it's going to be a whole lot less efficient than NBD. You're doing block io that gets replicated (say ... raid 1) by vinum and then then turned back into a block transaction by md and then into a network transaction through nfs back to a filesystem transaction on the remote machine (remember md is working on the file) which is then blocked by the remote filesystem. Did I miss anything? As I understand, NBD is just a little driver that lets you mount foo:/dev/ad0s1g over the network and proxies the block transactions across.
