Couldn't the same result be achieved storing a "virtual inode number" in an attribute? So that it gets replicated with the rest of the data and it makes possible to have the first subvolume always local... I understand tht it could lead to possible problems (like "how do I generate an inode number if the master node is missing"), but it could open to the "replicate writes, local reads" that many people are requesting... The scenario to think about is a firm w/ a remote office connected via a VPN -- if you can cut nearly all the read traffic from the VPN, then you see a great boost in performance.
