ZFS is on Leopard... Sorta.

Informationweek followsup on their previous quote that ZFS was not on Leopard. Brian Croll, senior director of Mac OS X Product Marketing, clarifies:

"ZFS is not the default file system for Leopard. We are exploring it as a file system option for high-end storage systems with really large storage. As a result, we have included ZFS -- a read-only copy of ZFS -- in Leopard."


This means that Leopard will be able to read ZFS volumes... assuming there was a way to write to one on Mac OS X, which there isn't... yet.

"Read-only means that at a later date, if there are ZFS volumes, those systems would be able to read ZFS volumes," Croll added. "You cannot write data into the system. It will allow you to read ZFS volumes later."

Well hopefully they will get it sorted, always good to have the latest and greatest.

If it were available as a boot option but not default I would probably use it.

So ZFS on Leopard will be like NTFS on Tiger? Tight.

Read-only? Lame. Weaksauce.

So much for Time Machine being incredible. Now it's just "really nifty."

Without being a developer I can't tell you if this is correct or not, but the first comment on the original article indicates that the Leopard Developer Beta allows you to create ZFS volumes via Disk Utility...

I really wanted ZFS to replace HFS+ completely in Leopard.

hmm.... I guess before we go through this again.

I'll move it to page two, until we hear otherwise.

Okay two things.
1) everyone who has thought time machine would use zfs does not understand how zfs works. I'll never understand why people who don't know what they're talking about like to pretend they do on the internet..there's plenty of things i don't know..i don't pretend to know any of them..

Time machine uses a second disk (or, an additional storage device). this is not how zfs snapshots work. zfs snapshots are created by not freeing the old data when modified data is written, that is all.

2) i am going to cry and cut myself if we're really stuck with a read only version of zfs...
btw, in the developer previews (9a410 was the only one i tried this in) you can easily create zfs volumes with the zpool command line utility. so does this mean they're going to gimp it? that makes me sad... i use zfs at work and i was really excited to have zfs on osx...

I can only hope that this isn't accurate...and i can at least have a fully functional zfs implementation via the command line. which is all i ask...

Can someone explain what is/what the advantages to ZFS are? The Wikipedia article is a bit too confusing for me.

Thanks in advance!
