A couple of interesting ZFS posts:
And some filesystem news from the Linux world showing definite signs of ZFS envy-
“The main purpose of Tux3 is to embody my new ideas on storage data versioning. The secondary goal is to provide a more efficient snapshotting and replication method for the Zumastor NAS project, and a tertiary goal is to be better than ZFS.”
“The new btrfs file system will be more convenient and robust than ext4, with some key features that couldn’t be incorporated without starting from scratch, and it is expected to leapfrog Sun Microsystems Inc.’s ZFS file system on several fronts.”
Personally I’m hoping that the only reason that Sun hasn’t GPL’d ZFS already is the lawsuit brought against them by Netapp and that as soon as litigation is over Sun will move quickly to GPL ZFS so we can have some ZFS goodness sooner rather than later on Linux (yes I know about ZFS on FUSE).
