ZFS For Mac OS X Source Code Available

nezmar writes "Noel Dellofano, who is part of the ZFS development team at Apple, has a post on Mac OS Forge announcing a late Christmas gift: he is making available binaries and source code, plus instructions, of the ZFS filesystem for Mac OS X."

I would imagine the kernel bits are significantly different, though mere availability of source, if not previously available, would likely help.

then you need to mkfs, and if you run out of space you're screwed because you can't easily grow. also, you can't create a newer fs, nor you can have snapshots, send/receive snapshots, volumes, have on-the-fly checksumming and disks that don't drop off the array at the first read error, one-line CIFS/NFS/iSCSI sharing. Get over it... zfs is better than md+lvm+ext3+whatever.

I'm not trolling, it's just that ZFS has been developed without the traditional and orthodox methods of disk-partition-filesystem and put everything on a single "layer", and instead of losing flexibility, we gain more, just because zfs developers were thinking outside the box (the now "traditional" way of doing things is segregation: the OSI layers, etc, claim to be more flexible, efficient and manageable than throwing everything together). I know, I know, veritas had this for years, so we could say that it was stole^H^H^H^H^Hcopied from them -- just as gates copied jobs, and jobs copied xerox.

Imagine the possibilities of breaking traditionalisms (like linux does "socially" but not "technologically").

a readonly version is included with leopard:

Honestly, what good is a file system if you can't write to it? Please enlighten me.

Not real sure, but you might want to ask the users of ISO9660 and UDF on optical media.

Sure will come in handy if/when it becomes the standard file system for Macintosh in the future. Just because write support is not rock solid at the moment does not mean read support is unwelcome.

For those of you who have not used Solaris yet, or aren't sure whether ZFS is up to the hype; that notation is "disk n of target 6 of controller 5." Your home server has absolutely nothing on the dreadnoughts from Sun. They sell a box with 50+ hotswap drive bays, and the CPU power to back it up (and it's not even the top of their line).

Take a look around at some of the other pages on that site. Amazing considering the one who wrote this script is 14 yrs old and is already doing some very impressive scripting and design. Keep at it and you will have no problems whatsoever finding a job! The world can certainly use more true hackers.

And people are not very happy about it:

But that doesn't stop the buzzword fanboys.

Doesn't work with iTunes?

[MessageDrivenBean]

From the FAQ: Downloading music via iTunes onto a ZFS target volume does not work yet. iTunes will complain it can't write to the volume. So there seems to be a link between iTunes and HFS+? Sounds like someone needs to do some reverse engineering...

Yeah, he's doing some absolutely awesome stuff. Makes me wish I could grow up now. On the other hand, I'll probably be dead once the world is flooded due to global warming and Mad Max meets Waterworld, so I shouldn't feel to bad for not having a computer when I was 14, I guess :-)
