Why not ZFS?

The 2006 Linux File Systems Workshop
As an old Multics hand, I looked at this and saw problems--and
solutions--similar to what we did with NSS in 1976, and later
with the volume scavenger. Of course, disks were about
1/10,000 the size we're talking about, but the problem (of
fsck taking too long) was the same.
However, we've learned a lot about filesystems since then, much
of which seems to be embodied in ZFS: snapshots, live scrubbing,
built-in integrity protection, etc. I haven't used ZFS, or
studied it in any detail, but it sure looks like it's trying to
solve these problems in a much more comprehensive way than just
carving up a gigantic ext3 into chunks.
