openZFS is doing pretty well on the BSD/etc side of things.   some of 
the original developers of ZFS, who long since bailed on Oracle, are 
contributing code thats not in the Oracle branch, they forked in 2010, 
with the last release from Sun, when OpenSolaris was discontinued.  The 
current version of OpenZFS no longer relies on 'version numbers', 
instead it has 'feature flags' for all post v28 features.  The version 
in my BSD 9.1-stable system has feature-flags for...

async_destroy                         (read-only compatible)
      Destroy filesystems asynchronously.
empty_bpobj                           (read-only compatible)
      Snapshots use less space.
lz4_compress
      LZ4 compression algorithm support.
