  • Have a look at wikipedia's Comparison of file systems [wikipedia.org] page to see the difference between ZFS & HFS+.

    The main advantage for HFS+ users (I mean who's really going to need a 16,000,000 Gigabyte file) would be the introduction of journalling beyond metadata (and even this is unlikely to be useful to most people).

      I think the major advantage is the fast snapshotting and cloning. It uses copy-on-write so that it doesn't take more space than what you actually change.

      Imagine being able to take really fast working copies of whatever you're doing and be able to simple use the old versions by cd'ing to the old clone.

      That's certainly what I would use ZFS for. The rest of the stuff, pooling and mirroring and stuff is less interesting in my laptop. :-)

            I can tell you grew up in the UNIX world. Everything I read about ZFS reminds me very much of VMS. Twenty years ago. If you read the UNIX Hater Handbook (published 12 years ago), then you will find a very nice rant about how the UNIX concept of partitions is a huge step back from what VMS offered. Now, over a decade later, it seems someone has listened.

              I agree that there was a lot in VMS that the world has "lost". I think that modern UNIX implementations should look at what VMS had, to reuse some of the good ideas that we still have not replicated. My favorite is the security system -- various small capabilities that each user (or program) could be granted. And the super-user only had one capability by default: the ability to grant privileges. I also appreciated the automated versioning, with the ability to pull up a previous version from the filesystem without having to use any special programs.

              And yes, I know that Windows NT is sort of descended from VMS. But I've not seen many of the concepts make it up to userland cleanly implemented.

              And I'm also aware that VMS is still around. It may not be on life-support yet, but it's clearly in the nursing home already.

However, when you're Microsoft, and you market your OS for Home Desktops, Workstations, File Servers, Database Servers, and just about everything else under the sun, it starts to make more sense to allow people to use different file systems.

HFS+ can be case-insensitive but case preserving or case sensitive depending on the options specified to create the volume. UFS doesn't have journaling support, HFS+ does. UFS stores POSIX metadata. HFS+ stores arbitrary metadata. UFS files have single fork. HFS+ files have a data fork and an arbitrary number of other forks. UFS stores the meta-data in the associated file's root inode. HFS+ stores it in a central database

    I very much wish for an updated filesystem for Mac OSX. I know that HFS plus (with journaling and meta-data searching where added later), I feel HFS + is showing signs of age. I was hoping when Apple first developed Mac OSX it had used the UFS system and then made a separate HFS+ partition for people who wanted to use a Mac OS9 on the PowerPC based Macs, but that didn't happen. Perhaps for the best at the time. Wilfredo Sánchez Vega wrote a whitepaper [wsanchez.net]on the reasoning for HFS + at the time

    So now with the Intel Macs and no need for Mac OS 9 support, Apple can tell all their developers that all Universal apps must be able to run on UFS. That way should Apple decide to adopt ZFS it should be a painless transition. Holding on to HFS + with the Intel Macs for this long will hamper any transition into a future filesystem. This will prepare Adobe and Microsoft to write their new Universal versions to be able to accept any type of filesystem and not rely on the resource fork of HFS

    That's my 2 cents.

    I just wish we could come up with a network file system that's worth the trouble. Right now, I'm using a Linux server with three Macs (two Tiger, one Panther), and everything is over NFS. Most of the time, it works fine, but if there's a weird hiccup, then the Mac will freeze solid and has to be hard power-cycled. Also, some apps simply won't run from a network share (or they'll run, but one thing or another won't be right). Install that app to a local drive, and it works fine. And this isn't even to mention security issues.

    I've looked at AFP, but that essentially mounts the remote system as if it were an external drive, and assigns everything to the logged in user, so ownership, permissions, etc., are all really screwy. Plus that gets even worse if you use fast user switching -- now two people are independently trying to mount the same network drive, each claiming to own it outright. And it doesn't look as seamless as, say, simply going to /Server/Shared or /Server/Apps.

    SMB isn't much better.

    There's always AFS, but that's so bloody complicated that I'd take a lot of convincing before I seriously considered it.

    This isn't even to mention the problems that most apps have in working in a networked environment -- applications simply aren't designed for, say, networked home directories, and *especially* aren't designed to be running simultaneously on multiple systems. So if I've got Mail.app running in the den and I log in upstairs to check mail just before I go to bed, things could get messed up.

    I'm not sure there's even been a new network file system since the mid 90's, has there? Certainly, nothing with broad support that fixes some of these issues? All I want is UNIX filesystem features -- simple locking (I guess), owners, regular permissions. Doesn't even need to do ACLs. Transparently mounted so it looks like it's part of the local filesystem. And at least reasonably tolerant of network glitches, so a momentary drop at the server (or whatever else happens to screw NFS connections to the wall) doesn't put all apps which have even heard of the mount point into an uninterruptible kernel-level deep-freeze (what's the point of kill -9, dammit?). Is that so difficult?

    The more I think about it, the more it makes sense for Apple to buy SUN. Their products nicely complement each other. Apple is strong in the consumer market and in the creative sector, SUN has good presence in the enterprise, tech and finance sectors. Apple has great brand value and knows marketing like no other computer vendor, SUN has technical excellence, but it's been struggling in the last years to actually sell their stuff. Their products portfolios have little overlap, and together they offer a very complete spectrum of computer products.

    Mac OS X is a great consumer OS, but performance at the high end is sub-par. For servers, Solaris is fast and scalable, has nifty features like ZFS and DTrace, but the UI is pretty crude. Imagine a merger of these. Looking at their market [yahoo.com] caps [yahoo.com], Apple can afford it.

      I like your comment. And the reason why I like it so much has to do with my (past) experience on a University system. Universities developed servers and file sharing with Macs using Sun's servers because Apple really didn't have a server. I mean you could put a Mac (usually an older one) on a network and tell it to share files with everyone but it lacked lots of stuff you would expect to have in a server and it tended to be pretty slow.

      I would argue that it was the University exposure that lead Apple to offer Ethernet on Macs. Appletalk was great and people hooked themselves up very quickly with Appletalk (you could buy cabling at your local Radio Shack or use almost any twisted-pair cabling, including electrical cables) but Ethernet was a lot faster and more reliable. I'll bet the folks who developed 10 Base-T Ethernet were thinking Appletalk when they came up with the design for the connector and the twisted pair.

      But I digress...

      I did a fair amount of work with a hard Science department and they all had Suns as servers. They were strictly Sun Unix for the geeks and they developed systems and applications on that model. But for those who actually had to function in an office environment, the Macs were standard. They used Microsoft's Office for memos, reports and spreadsheets and TeX for document publishing. Everything you did worked.

      Frankly, I think this legacy is part of the reason why Apple got fascinated with Unix again (that, and Jobs' NeXt company). It would be a good marriage. Apple's X-Serve RAIDs with Sun. Sweet!

    But Dvorak said Apple was switching to Windows! How could this possibly be true?
