Re: HAMMER and RAID question

I am not purposefully trying to be difficult, but rather trying to understand.

    Theoretically the B-Tree could be used to list multiple copies of

    of the filesystem rather than trying to maintain redundancy within
    a single copy of the filesystem.

My thinking that having the mirroring within the filesystem, combined with the reblocking code, hot swap (connect/disconnect) and the smart mountpoints would actually be a very smooth experience also in single-server configurations.

Ah, there always /is/ hardware RAID. Maybe that would still just be the way to go.

Thank you for your answer!
