Apple’s Mac OS X Leopard to feature ZFS?

Apple Store“Over the past couple of years, there’s been a lot of talk about bringing ZFS, Sun’s open source high-performance file system, to Mac OS X. Our man Siracusa first pointed out a message from an Apple developer last year expressing a desire to work on porting the file system to Apple’s OS, and talked more about its possible ties (or lack thereof) to Time Machine not long after. Even more recently, ZFS became accessible under OS X thanks to the MacFUSE project. Still, there’s been little word on the state of ZFS for OS X recently,” Erik Kennedy reports for Ars Technica.

“Now, it looks as though the port is not just wishful thinking, but an active project,” Kennedy reports.

  1. ZFS is a next-gen file system with some excellent data-integrity and data-cloud abilities. Of course, if you don’t care about file systems, you won’t care about this. In that case, what it means is: more and better options, and a improved file experience. If you want to know more, go read Ars.

  2. ZFS is a new kind of file system. It will probably eventually replace HFS+ which is what most Mac users currently use. ZFS can scale better and is more resilient than other older alternatives like NTFS, used by Windows.

  3. Leopard will likely support ZFS through disk utility (it’s removed in the more recent Leopard builds), but the OS file system will still be HFS+. ZFS will probably come in with the next OS update (10.6 vs. OS 11).

  4. Thought it was common knowledge:

    1. ZFS is a formatting option in the dev previews (yea!). But bootable? Dunno.
    2. TimeMachine does not use ZFS. I don’t know what it uses… But zfs has time machine like abilities for making lightweight snapshots/checkpoints of entire filesystems. (Double yea!)

    ZFS support is seriously cool for wrapping up collections of disks into one big disk image. And end user would care since this sort of thing allows you to just add disks to your system and the single filesystem that you keep everything in would just appear to get bigger. No reformatting or partitioning. Plus your data is spread out over the disks. So if one dies it’s no big deal. Just put a new one in and your good to go.

    It’s almost magic.

  5. I thought I read that one of the cool benefits of ZFS was that you could add new hard drives to your system and instruct your computer to treat them all as one big hard drive. It works transparently in the background, so it looks like 1 big drive. That’s pretty nifty. Every time I buy a new drive, I’ve got to rearrange my files, which is a bit of a pain.

  6. Here’s to hoping that Leopard is MILES ahead of Vista, not just on usability and security (which is already true w/Tiger), but also on powerful new features and under-the-hood improvements. Time to blow away Vista with features that M$ will not be able to copy for years, no matter how much money they throw at it!. Let’s put the M$ geeks to SHAME!
    GO APPLE!

  7. As a long time UNIX user and SA, ZFS and its SUN heritage means at least one thing: Apple is starting to taking the Enterprise more seriously. It should have pride of place in the new Leopard Server, and it’s another smack-down against Microsoft’s NTFS.
