"LVM, MD, DM, and lots of other FS-related features can be combined in different ways that will accomplish do the vast majority of what ZFS does."

No, they can't. They don't give you self-repairing storage with provable data correctness. They don't give you dynamic striping. The LVM still requires you to manually carve up PVs into LVs. ext3 doesn't support arbitrary number of extended attributes. I could go on.

Further, just because the GPL is not compatible with Sun's implementation of ZFS, is no reason that the Linux kernel community couldn't reimplement ZFS. The on-disk format and man pages are available at http://opensolaris.org/os/community/zfs/docs/ I think this could be a valuable piece of software for the Linux kernel.
