    Ok, here's the final design document that I am now implementing.
    Again, I expect most or all of these features to be ready and the
    filesystem to be beta-quality by the December release.
Wow, this seems pretty good.

What about data corruption issues ?

Have you thought about implementing some sort of checksumming mechanism ?

We cannot assume hardware to be absolutely reliable. There may be some
silent corruption going on the disk or network layers, etc...
According to Matt's design document:

    "All information in a HAMMER filesystem is CRCd to detect
     corruption."
