ZFS To Become Default File System In Leopard

Basically, a couple of the big things are that ZFS will really work nicely with Time Machine, and the whole idea of pooled storage.

Right now, if your hard drive fills up, even if you have space for another hard drive, you add the new one in, format it, and it appears as a separate volume. Say now you have your old 160GB volume plus a new 500GB volume. You have to decide if you want to clone all the contents of your old drive onto the new drive and then get rid of the old drive, only keep certain kinds of files on the new drive (then you have to remember to navigate there, etc, etc). In ZFS, the basic idea is that, you had 160GB of space, you plug in the new drive, now you have 760GB of space -- the new hard drive gives you new space without having to copy things over or use different volumes or anything like that.

So much like RAID0, what happens if one of the drives in the pool dies? Wouldn't all data be lost since pieces of files might be on both drives? Personally, I'd rather keep the 160GB and 500GB (which equals 660 btw ;)) separate so if one drive dies I'm not completely screwed
 
"OS 10" all over the place makes me cringe.

And as far as requiring you to install on another HD and move stuff over, there's no way they can expect people to do that. Sure, lots of people have external hard drives, and that number is only going to increase with Time Machine, but that doesn't seem like something Steve-O would approve.
 
I have various firewire drives that I keep different projects on. Isn't it going to get confusing if I don't know which volume I'm saving stuff to?

Is it just me or was that real-video clip pulled?!?!

Damn I freakin went out of my way to download that cruddy player and all for nothing... If a mirror exists please let me know.

The File Recovery (NOT Time Machine) in Leopard said 'HFS+ only' in the builds...do you think it will work?

All of your drives would be separate unless you specifically choose otherwise. Nothing will change unless you tell OSX to combine your drives into 1 pool. At least I'd hope so....

I'd need to understand more about that too... from what I understand, it's less of an issue than it seems. I guess it is geared, however, at people who have some kind of backup on a separate drive system.
 
Is there smoke coming out of Steve's ears today with this slip announcement? Or was it even a slip? Is this another RDF pre-wave for WWDC? :cool:
 
For shame, Sun. :(
Oh well, sounds cool at least. If it does indeed make the OS "snappier", then that's fantastic.

Elaborate, please? ;) I think that previous poster had a valid point to some extent... if you have an intelligently spanned ZFS array with more than one drive, and one of them fails while it has data on it, you must either have the ZFS configured so that data is fully redundant on another drive within the system, or the backup is kept on a separate set of drives. I don't see any other way to get around the issue of how to recover if you have two drives pooled together and one of the drives fails. My understanding is ZFS deals with this, but not in a scenario like the one that poster mentioned, where you have just two drives of different sizes and there's no way to achieve full physical redundancy.
 
So whats the difference with ZFS to the current file system? Apart from the max size you can have stored on it.. is it faster?
 
i'm hoping that apple come up with an easy way to change the filesystem, even if it includes a archive and install i'd be happy.
 
I've used various files systems on linux. I can't remember which one now, but I was able to add a drive and extend the volume size. It's a nice feature.

I hope apple supports reading and writing from more file systems. I had a heck of a time getting OS X to read a linux drive that was used for storage.
 
Nice that Apple doesn't suffer "Not In Here" syndrome like Microsoft.

They discover good technologies and see if they'll be useful to them, and then use them.

I doubt that ZFS would have been a major announcement at WWDC anyway, but the pre-announcement has probably annoyed a few people. Oh well.

I'd be very curious to see if Apple could wrangle a way to license and incorporate MacFUSE as part of OS X. They're certainly on good terms with Google.

Was anyone else hoping that this wouldn't be the case? ZFS is definitely an improvement over HFS+, but there are new file system advancements that aren't in ZFS, and I'd like for Apple to use something cutting edge.

Oh please no. In the past I took bets on "cutting edge" filesystems and watched them melt down under load (Spiralog and ReiserFS of several years ago come to mind). Lesson learned: the time saved by having a mature filesystem that stays consistent is far more important than cool new features that haven't yet had the time to be battle hardened.
