ACM's latest journal had an interesting article about RAID which suggested it might be time for triple parity raid. "How much longer will current RAID techniques persevere? The RAID levels were codified in the late 1980s; double-parity RAID, known as RAID-6, is the current standard for high-availability, space-efficient storage. The incredible growth of hard-drive capacities, however, could impose serious limitations on the reliability even of RAID-6 systems. Recent trends in hard drives show that triple-parity RAID must soon become pervasive."

3. If you think ZFS is neat, I strongly recommend throwing your support behind btrfs. It's not as good as ZFS, but you will eventually be able to trust your data to it on Linux.
Is there any particular reason that btrfs isn't as good?
Last time I checked, it seemed to be a couple of missing features away from being equivalent to the first versions of ZFS.
Is it just a matter of being younger?

I think you answered your own question there.
But Btrfs is a great filesystem embryo and I'm looking forward to using it some time in the future, when it's more equivalent to the current versions of ZFS.

According to its web site, "btrfs is under heavy development and is not suitable for any uses other than benchmarking and review. The btrfs disk format is not yet finalized but it will only be changed if a critical bug is found and no workarounds are possible."
In the mean time, if you need a robust production file system I would recommend choosing a mature file system that's more appropriate for your needs. For example, GFS or OCFS2 are enterprise ready clustered file systems. They are both GPL licensed but I wouldn't be so concerned about licensing unless you have overwhelmingly strong beliefs that require you to strictly adhere to superstitions instead of relying on more rational metrics like performance and stability.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.

The day has finally come: Google has started shipping Google Glass to the lucky few early adopters. Now that it's shipping, Google has also unveiled a lot more about the API and the specifications of the device itself. While the company had already given out substantial details at earlier occasions, there are still a few surprises here.

Almost exactly three years ago, I wrote about why OSNews was no longer OSNews: the alternative operating system scene had died, and OSNews, too, had to go with the times and move towards reporting on a new wave of operating systems - mobile, and all the repercussions that the explosion of smartphones and tablets have caused. Still, I was wondering something today: why aren't we seeing alternative operating systems on mobile?More Features »

I worked on the Linux ZFS port using FUSE.
1. Some people feel that FUSE filesystems are second class citizens on Linux. I happen to agree, but you may not.
2. Quite apart from the fact that it's a FUSE filesystem, zfs-fuse has bugs. Some people wake up one morning and their pools don't import. Sometimes this can be fixed with specialized single-purpose tools from the author and sometimes they can't. For more zfs-fuse failures, check the mailing list.
