ZFS for Mac OS X Breaths New Life

#1
I'm not sure how many folks have been mourning the seeming loss of ZFS for Mac OS X for as long as I have... but I thought that this was not only great news, but a tremendous opportunity for folks to really pitch in and help a very worthwhile project for those who value their data!

Very exciting!

For those (like me) who are clueless on what ZFS is, the wiki page has a good overview:

  In computing, ZFS is a combined file system 
  and logical volume manager designed by Sun 
  Microsystems. The features of ZFS include 
  data integrity (protection against bit rot, 
  etc), support for high storage capacities, 
  integration of the concepts of filesystem 
  and volume management, snapshots and 
  copy-on-write clones, continuous integrity 
  checking and automatic repair, RAID-Z and
  native NFSv4 ACLs.

ZFS is really cool. The best things that stood out out to me when I researched it a bit a while ago (though there is so much cool about it) are

1) more storage than you could ever possibly use–you won't run out. 2) you can add and remove drives on the fly. 3) you don't have drives you mount, you have pools you can add to and remove from (on the fly). 4) great redundancy/error-checking built in, in all forms.

I'd love to see it on the Mac, officially…

You can add and replace, but you cannot remove drives.

"Breaths new life" is a bit misleading' no? From the project page: "this code project will be used to record issues and ongoing development (if any) of this extension"

As well, only a single commit to the git repo since July. :(

Sure you can. You just can't shrink the size of a pool.

the forum is very active, especially alex blewitt. There are fairly infrequent updates, but it's definiatly being developed.

The best feature is that you can tell it to do a "zpool scrub poolname" and it will go through the entire set of drives in that pool and check the checksums, correcting as necessary. Given that there are errors that can occur silently, ZFS can detect and correct them if they are single-bit errors.

Does anyone know if Oracle is still developing ZFS, or just Btrfs? Has the situation changed so that Apple may include it on next iterations of OS X, or are we stuck with HSF+ forever?

ZFS development continues; they recently released encryption support. Based on the rumors, it sounds like Apple is now writing their own filesystem.
