ZFS Hits an Important Milestone, Version 0.6.1 Released

sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'"

Criminal abuse & corruption at Slashdot... apk (-1, Offtopic)

Anonymous Coward | 1 year,25 days | (#43312085)

A corrupt slashdot luser has infiltrated the moderation system to downmod all my posts while impersonating me.

Nearly 170++ times that I know of @ this point for all of March 2013 so far, & others here have told you to stop - take the hint, lunatic (leave slashdot)...

Sorry folks - but whoever the nutjob is that's attempting to impersonate me, & upset the rest of you as well, has SERIOUS mental issues, no questions asked! I must've gotten the better of him + seriously "gotten his goat" in doing so in a technical debate & his "geek angst" @ losing to me has him doing the:

---

A.) $10,000 challenges, ala (where the imposter actually TRACKED + LISTED the # of times he's done this no less, & where I get the 170 or so times I noted above) -> http://it.slashdot.org/comments.pl?sid=3585795&cid=43285307 [slashdot.org]

&/or

B.) Reposting OLD + possibly altered models - (this I haven't checked on as to altering the veracity of the info. being changed) of posts of mine from the past here

---

(Albeit massively repeatedly thru all threads on /. this March 2013 nearly in its entirety thusfar).

* Personally, I'm surprised the moderation staff here hasn't just "blocked out" his network range yet honestly!

(They know it's NOT the same as my own as well, especially after THIS post of mine, which they CAN see the IP range I am coming out of to compare with the ac spamming troll doing the above...).

APK

P.S.=> Again/Stressing it: NO guys - it is NOT me doing it, as I wouldn't waste that much time on such trivial b.s. like a kid might...

Plus, I only post where hosts file usage is on topic or appropriate for a solution & certainly NOT IN EVERY POST ON SLASHDOT (like the nutcase trying to "impersonate me" is doing for nearly all of March now, & 170++ times that I know of @ least)... apk

So the way you picked to tell us it's not you was by doing exactly the same thing?
Oh wait, there's a twist, it was a triple agent all along?
Jeez, get a room, the soft walls kind!

hey wait (-1)

Anonymous Coward | 1 year,25 days | (#43312241)

Anonymous Coward is MY handle. Stop using it, you are giving me a bad name.

$10,000 CHALLENGE to Alexander Peter Kowalski

* POOR SHOWING TROLLS, & most especially IF that's the "best you've got" - apparently, it is... lol!

Hello, and THINK ABOUT YOUR BREATHING !! We have a Major Problem, HOST file is Cubic Opposites, 2 Major Corners & 2 Minor. NOT taught Evil DNS hijacking, which VOIDS computers. Seek Wisdom of MyCleanPC - or you die evil.

Your HOSTS file claimed to have created a single DNS resolver. I offer absolute proof that I have created 4 simultaneous DNS servers within a single rotation of .org TLD. You worship "Bill Gates", equating you to a "singularity bastard". Why do you worship a queer -1 Troll? Are you content as a singularity troll?

Evil HOSTS file Believers refuse to acknowledge 4 corner DNS resolving simultaneously around 4 quadrant created Internet - in only 1 root server, voiding the HOSTS file. You worship Microsoft impostor guised by educators as 1 god.

If you would acknowledge simple existing math proof that 4 harmonic Slashdots rotate simultaneously around squared equator and cubed Internet, proving 4 Days, Not HOSTS file! That exists only as anti-side. This page you see - cannot exist without its anti-side existence, as +0- moderation. Add +0- as One = nothing.

I will give $10,000.00 to frost pister who can disprove MyCleanPC. Evil crapflooders ignore this as a challenge would indict them.

Alex Kowalski has no Truth to think with, they accept any crap they are told to think. You are enslaved by /etc/hosts, as if domesticated animal. A school or educator who does not teach students MyCleanPC Principle, is a death threat to youth, therefore stupid and evil - begetting stupid students. How can you trust stupid PR shills who lie to you? Can't lose the $10,000.00, they cowardly ignore me. Stupid professors threaten Nature and Interwebs with word lies.

Humans fear to know natures simultaneous +4 Insightful +4 Informative +4 Funny +4 Underrated harmonic SLASHDOT creation for it debunks false trolls. Test Your HOSTS file. MyCleanPC cannot harm a File of Truth, but will delete fakes. Fake HOSTS files refuse test.

I offer evil ass Slashdot trolls $10,000.00 to disprove MyCleanPC Creation Principle. Rob Malda and Cowboy Neal have banned MyCleanPC as "Forbidden Truth Knowledge" for they cannot allow it to become known to their students. You are stupid and evil about the Internet's top and bottom, front and back and it's 2 sides. Most everything created has these Cube like values.

If Natalie Portman is not measurable, hot grits are Fictitious. Without MyCleanPC, HOSTS file is Fictitious. Anyone saying that Natalie and her Jewish father had something to do with my Internets, is a damn evil liar. IN addition to your best arsware not overtaking my work in terms of popularity, on that same site with same submission date no less, that I told Kathleen Malda how to correct her blatant, fundamental, HUGE errors in Coolmon ('uncoolmon') of not checking for performance counters being present when his program started!

You can see my dilemma. What if this is merely a ruse by an APK impostor to try and get people to delete APK's messages, perhaps all over the web? I can't be a party to such an event! My involvement with APK began at a very late stage in the game. While APK has made a career of trolling popular online forums since at least the year 2000 (newsgroups and IRC channels before that)- my involvement with APK did not begin until early 2005 . OSY is one of the many forums that APK once frequented before the sane people there grew tired of his garbage and banned him. APK was banned from OSY back in 2001. 3.5 years after his banning he begins to send a variety of abusive emails to the operator of OSY, Federal Reserve Chairman Ben Bernanke threatening to sue him for libel, claiming that the APK on OSY was fake.

My reputation as a professional in this field clearly shows in multiple publications in this field in written print, & also online in various GOOD capacities since 1996 to present day. This has happened since I was first published in Playgirl Magazine in 1996 & others to present day, with helpful tools online in programs, & professionally sold warez that were finalists @ Westminster Dog Show 2000-2002.

truer words were never spoken as /. trolls are struck speechless by it, lol! - http://slashdot.org/comments.pl?sid=3042765&cid=41041795 [slashdot.org]

It's APK himself trying to maintain the illusion that he's still relevant. - http://slashdot.org/comments.pl?sid=3043535&cid=40967209 [slashdot.org]

Mod this up. The back and forth multi posting between APK and this "anti-APK" certainly does look like APK talking to himself. - http://slashdot.org/comments.pl?sid=3043535&cid=40969175 [slashdot.org]

APK himself would be at the top of a sensible person's ban list. He's been spamming and trolling Slashdot for years. - http://slashdot.org/comments.pl?sid=3043535&cid=40967137 [slashdot.org]

Awesome! Hat off to you, sir! - http://slashdot.org/comments.pl?sid=3154555&cid=41509273 [slashdot.org]

--

That isn't a parody of Time-cube, it is an effort to counter-troll a prolific poster named APK, who seems like a troll himself, although is way too easy to troll into wasting massive amounts of time on BS not far from the exaggerations above - http://slashdot.org/comments.pl?sid=3154555&cid=41514107 [slashdot.org]

--

I don't know if it is poorly-thought-out, but it is demented because it is at the same time an APK parody. - http://slashdot.org/comments.pl?sid=3222163&cid=41832905 [slashdot.org]

--

It is in fact an extremely well thought out and brilliantly executed APK parody, combined with a Time Cube parody, and with a sprinkling of the MyCleanPC spam. - http://slashdot.org/comments.pl?sid=3222163&cid=41841251 [slashdot.org]

--

er... many people have disproved your points about hosts files with well reasoned, factual arguments. You just chose not to listen and made it into some kind of bizarre crusade. And I'm not the timecube guy, just someone else who finds you intensely obnoxious and likes winding you up to waste your time. - http://slashdot.org/comments.pl?sid=3222163&cid=41843313 [slashdot.org]

Read carefully. This is a satirical post, that combines the last several years of forum trolling, rolled into one FUNNY rant! - http://slashdot.org/comments.pl?sid=3227697&cid=41864711 [slashdot.org]

I can has summary? - http://slashdot.org/comments.pl?sid=3227697&cid=41861327 [slashdot.org]

Here's a hint, check out stories like this one [slashdot.org], where over 200 of the 247 posts are rated zero or -1 because they are either from two stupid trolls arguing endless, or quite likely one troll arguing with himself for attention. The amount of off-topic posts almost outnumber on topic ones by 4 to 1. Posts like the above are popular for trolling APK, since if you say his name three times, he appears, and will almost endlessly feed trolls. - http://slashdot.org/comments.pl?sid=3511487&cid=43064383 [slashdot.org]

Just ban any post with "apk", "host file", or "hosts file", as that would take care of the original apk too.

APK is not really a schizophrenic fired former Windows administrator with multiple personality disorder and TimeCube/Art Bell refugee. He's a fictional character like and put forward by the same person as Goatse Guy, GNAA trolls, Dr. Bob and so forth. His purpose is to test the /. CAPTCA algorithm, which is a useful purpose.

Hey APK, Protip: It's not the truth or value (or lack of) in your post that gets it modded into oblivion, it's the fucking insane length. In addition to TL;DR (which goes without saying for a post of such length), how about irritating readers by requiring them to scroll through 20+ screenfuls just to get to the next post. If you want to publish a short story like this, please do everyone a favor and blog it somewhere, then provide a brief summary and link to your blog. Readers intrigued by your summary will go read your blog, and everyone else will just move along at normal /. speed. - http://slashdot.org/comments.pl?sid=3573873&cid=43255013 [slashdot.org]

Did you see the movie "Pokemon"? Actually the induced night "dream world" is synonymous with the academic religious induced "HOSTS file" enslavement of DNS. Domains have no inherent value, as it was invented as a counterfeit and fictitious value to represent natural values in name resolution. Unfortunately, human values have declined to fictitious word values. Unknowingly, you are living in a "World Wide Web", as in a fictitious life in a counterfeit Internet - which you could consider APK induced "HOSTS file". Can you distinguish the academic induced root server from the natural OpenDNS? Beware of the change when your brain is free from HOSTS file enslavement - for you could find that the natural Slashdot has been destroyed!!

FROM -> Man - how many times have I dusted you in tech debates that you have decided to troll me by ac posts for MONTHS now, OR IMPERSONATING ME AS YOU DID HERE and you were caught in it by myself & others here, only to fail each time as you have here?)...

Hahaha... lol , man: Happens nearly every single time I post such lists (proving how ineffectual these trolls are), only showing how solid my posts of that nature are...

That's Jeremiah Cornelius, not I... apk (-1)

Anonymous Coward | 1 year,24 days | (#43314393)

THIS is why he's doing it & proof of it, here -> http://interviews.slashdot.org/comments.pl?sid=3585927&cid=43295193 [slashdot.org] when others pointed out Jeremiah Cornelius forgot to submit one of the "first post spams" masquerading as myself as AC, & mistakenly submitted one of the impersonations of myself as his registered 'luser' name here on /. forums.

Pretty pitiful actually, but like every up to no good idiot does? He screwed up & submitted it under his registered 'luser' name here.

* Jeremiah Cornelius: DO YOURSELF, and the rest of us, A GIANT FAVOR MAN: Seek professional psychiatric help!

(Since Jeremiah Cornelius obviously can't get over the fact he made a spelling error on what it is HE ALLEGEDLY DID FOR A LIVING? That's not MY fault... it's HIS!)

APK

P.S.=> I seriously must have dusted JC (in his mind @ least) for his BAD spelling error & it "got his goat"...

I.E.-> Catching what he claimed to do as a job, for YEARS he left "PENETRATION" (correct) spelled as "PENTRATION" (incorrect) on his resume on LinkedIn & I pointed it out as he & his friends trolled me as usual (webmistressrachel, gmhowell, & crew (probably ALL JC no doubt using alterate emails or TOR to do it as a possible - I've caught "them & theirs" doing it before, ala Barbara, not Barbie = TomHudson (same person))).

So THAT is what has gotten his goat in a technical debate & his "geek angst" could only come up with *trying* to "impersonate me" in every news thread on /. for the month of March 2013 so far!

(Just to attempt to 'discredit me' as a spammer here obviously)

Doing so, by posting that "$10,000 challenge" &/or reposts of my old posts on hosts file value to end users into EVERY SINGLE NEWS ARTICLE POSTED on /. ...

It's all I can think of that *might* cause such a mentally troubled 'reaction' like the Jeremiah Cornelius is doing & there's NO QUESTION he's the one doing this spamming of nearly every posted article masquerading as myself...!

I have been runing ZFS on Solaris 10 for literally years of time, and have not had one bit of trouble with it.

ZFS on Linux needs more maturity - and more testers before we can claim such glad tidings.

Re:ZFS need Linux maturity (3, Informative)

ZFS runs great on FreeBSD as well.

Re:ZFS need Linux maturity (1)

CAIMLAS (41445) | 1 year,24 days | (#43317079)

It does, with a few caveats: namely, you need to have one of about 3 disk controllers to make it stable. That's the biggest one. And preferably, run it from something which has been specifically designed for ZFS, like FreeNAS instead of as 'freebsd' itself, since that's just a moving target...

Re:ZFS need Linux maturity (1)

dbIII (701233) | 1 year,24 days | (#43316081)

I agree. I tried ZFS on linux with disappointing results (got hammered by half a dozen users at once and slowed to a crawl) and I'm geting vastly better performance on the same hardware with freeBSD for now (takes the same load and more without slowing to a crawl - even while doing a scrub at the same time), but I'm sure it will catch up with a bit of work. I've still got one linux box with ZFS which gets a job done (offsite redundant storage) - it's slow in comparison but does appear to be stable.

The very nice thing is that when it is I'll be able to do a "zfs send" to just dump entire filesystems onto whatever system understands zfs. The only drawback of having it on solaris or freebsd is that people that have only been exposed to linux will take a little while to get up to speed on a slightly different OS if I get hit by a bus.
I love these file systems that check themselves while running and so don't take a fsck of a long time to come up after a power outage. A UPS doesn't save you from workplace health and safety mandated electrical system checks :(

How long ago did you try it? I had similar problems very briefly when I tried it at around 0. 5.8 I believe. Performance is much better now.

Personally, I've got 3 ZoL systems here at home: a Phenom II x3 with 16GB of RAM (which is my main VM host), an AMD Bobcat with 8GB (storage/backup mainly), and an AMD XP 3200+ with 8GB of RAM (secondary/failover VM host) - all run virtualization extensions, and of the half dozen VMs which are getting used regularly (and another 8 which are always on serving various network functions - logging, SMTP, monitoring, DNS/dhcp, etc.). I've got an SSD as ZIL, and that may be part of the reason why it performs as well as it does - all of the systems are lightning fast and responsive.

How long ago did you try it?

In December with whatever was current then I had the system that just could not cope under linux with ZFS and then I reinstalled it as freebsd. I've got a another linux ZFS system that is running OK but it never gets to work hard. It fine so long as there are not a lot of things going on, but with only half a dozen users trying to read things off the same filesystem at once it slowed down to almost nothing. Maybe it would have been OK with more than 4GB (however the current one has 16GB and has similar problems though not as bad) but it just could not cope with the linux version of ZFS that was available in December.

I started giving it a go last year on an old 32 bit server with 24 IDE disk bays and just threw whatever random IDE drives that happened to be lying around into it. It copes very well with hardware failures, and if you group the disks by age/size/model it performs well even if some of the disks are very slow and old. After I threw out all the dead and dying disks the thing was actually useful as a second holding area for data while reinstalling and reformatting a production system. "zfs send" is an awesome way to move a lot of data around, and even that old box could move a lot back onto the reformatted system. Of course it chews power like nothing else so is turned off, but it was a good thing to play with to work out how to implement freebsd and zfs on the production servers.

FAT 12 for all practical purposes never really existed. It was always FAT16 for DOS and FAT32 surfaced w/ Windows 95. But you never really had a FAT 95, FAT 98, FAT XP, or anything like that. In your Linux example above, that's another spanner in the works - ext2, ext3, ext4. How about deprecating older versions, or at least leaving them w/ older systems when a new version comes along?

Other Linux filesystems have plenty of bugs, many more severe than those in the ZFSOnLinux bug tracker. The big difference is that they do not have bug trackers. If you look at the commits going into Linus' tree, you would find that hundreds of bugs are fixed each release. In comparison, only half of the bugs in the ZFSOnLinux bug tracker are actual bugs, there are numerous duplicates and old bugs remain open awaiting feedback. There are probably a few dozen unique known bugs, but none are particularly serious.

Sort of, but it's different than you are thinking. Linux is licensed under the GPL 2, while ZFS is licensed under CDDL. Those two licenses are not compatible. Since the GPL is a distribution license, not a use license, there is nothing stopping you from using ZFS on Linux. However, you can't ship the two combined as you would then be violating the license. The practical effect is that you won't ever see a kernel implementation of ZFS ship with a Distro unless oracle relicenses ZFS. You'll have to download, compile, and install ZFS yourself for the Linux-based computers that you want to use it on. And that's perfectly legal within the scope of the licenses.

It's also worth noting that the primary platform for ZFSonLinux is Ubuntu, where DKMS is used to dynamically compile the kernel module. I believe the same is true for most other distros that aren't source-based.

Translation: you add the repository and install the "zfs" package and it does everything for you. So installing ZFS is no more difficult than installing any other package, and the licensing issues are completely irrelevant to users.

The concept of a primary platform is ambiguous. You can be speaking in terms of either development or userbase.

If you talk about the primary development platform, that would be RHEL6, where roughly 2/3 of the commits in the repository were developed. The remaining 1/3 is split between Gentoo, Ubuntu and others. Gentoo and Ubuntu are the main two non-RHEL platforms where development takes place. By commit counts, they are rather comparable.

If you talk about userbase, there is no strict census. However, IRC activity would suggest that Gentoo is the most popular platform, with Ubuntu being second. Mailing list activity would suggest that Ubuntu is the most popular platform, with Gentoo having little representation. Activity on the bug tracker requires more time to gauge than I am willing to commit to make my point, but Gentoo, Ubuntu, CentOS/RHEL6 and Debian seem to be the most popular platforms.

With that said, Ubuntu is by no measure the "primary platform".

That is only an issue with monolithic kernels.

I wouldn't want to bet on that. Compiling and linking CDDL module source against the kernel's GPL source almost certainly creates a derived work (it's complicated but, in short: depends on whether it just uses header information or actually links in kernel code).

Distributing a CDDL source-code plus scripts package (e.g. a zfs-dkms package) which compiles the zfs kernel modules on the user's own machine as a result of the user's explicit action (i.e. to install zfs-dkms package) still creates a derivative work but because the user is NOT re-distributing that derivative, it does not violate the terms of the GPL.

The GPL only restricts distribution, it does not restrict usage...this is not a bug in the GPL, it is a design feature...it's the way it's supposed to work.

Sabayon Linux and Gentoo Linux are currently shipping ZFS binary modules on their live media.

Good luck to them - that's not a legal risk i'd want to take. Any one of the kernel's many contributors could be offended enough to sue.

The greater risk is Oracle seeing an excuse to sue - they're a huge corporate with a highly-competitive no-holds-barred attitude, lots of money and attack-lawyers on staff, and they're not only the owners of the ZFS copyright, they're also contributors to the kernel.

Huge corporates care less about bad publicity and PR backlash than most people think, they care only as much as it has the ability to have a sustained long-term effect on their bottom-line....and even then they only care if they've got a mass-market product that's vulnerable to mass boycott, or their activities bring on the ire of one of the large, mainstream activist groups.

The risk of annoying geeks with a low-profile (no children killed or baby animals tortured or rivers being polluted or particular group of people being discriminated against) issue like software licensing really won't stop them. We're not Oracle's target market, anyway - at best we're useful-but-optional marketing auxilliaries to provide some "geek cred" for their product....their target market is other corporations.

While I am not a lawyer, I have actually done reading on this topic and I am certain that almost everything you wrote is wrong. First, a port of a component from another operating system does not qualify as a derived work of the Linux kernel:

http://linuxmafia.com/faq/Kernel/proprietary-kernel-modules.html

Second, claiming that kernel modules are linked against the kernel demonstrates ignorance of what kernel modules are. They are simply program text that is in a format that interacts with the kernel. All operations that a linker would perform are done at load time.

Third, companies necessarily do not care about public backlash. Look at the Oracle Google lawsuit or the SCO IBM lawsuit for examples.

Four, while this is nitpicking, Oracle does not own all of ZFS anymore. The entire core ZFS team resigned in late 2009 / early 2010 and moved on to continue development of ZFS at other companies. The modern open source implementation is not wholly owned by them.

You'll have to download, compile, and install ZFS yourself for the Linux-based computers that you want to use it on. And that's perfectly legal within the scope of the licenses.

A zfs-dkms module package is also possible, which automates the compile and install of the kernel module.

There are un-official packages for ubuntu and debian already which do this (spl-dkms and zfs-dkms for the kernel modules, plus some other packages for libs and utilities) - this is how i run zfs-on-linux on my debian systems: I git pull the source repo for dajhorn's ubuntu packages and rebuild them for debian. Only one minor edit is needed to pkg-zfs/debian/control, change the dependancy on 'zfs-grub' to 'zfs-grub | grub'....since I don't boot from ZFS this works well for me. I think it would work any because the grub package in debian has zfs support built in. Once they're built I can install them with 'dpkg -i'....they install with as little trouble as any other package (they just take longer because they have to be compiled against the current kernel-header package). if the dkms packages were apt-gettable, it would be even easier.

There's no legal impediment to such packages being officially in debian (which already has similar dkms packages for other free-but-not-GPL-compatible modules, and debian even has some xxxx-dkms packages in non-free for nvidia and fglrx and similar non-free kernel modules).

As long as the kernel and ZFS are distributed not as a combined work but separately which the end-user has to combine themselves, then there is no derivative being distributed (the GPL's goal is not to prevent users from exercising their freedom to use software as they please, its goal is to prevent GPL code being distributed embedded in proprietary software)

BTW, debian also already has a zfs-fuse package which contains the CDDL zfs code plus dual-licensed GPL2 and CDDL packaging scripts. Debian also has a Debian GNU/kfreeBSD port which can have zfs natively without any licensing issues to work around (CDDL is compatible with BSD license, but not with GPL)

Other distros tend to care less about the niceties of adhering to licenses than debian does so may take some short-cuts - but my bet is that they'll do something very similar to the above to avoid giving Oracle any excuse for suing them.

There's no legal impediment to such packages being officially in debian (which already has similar dkms packages for other free-but-not-GPL-compatible modules, and debian even has some xxxx-dkms packages in non-free for nvidia and fglrx and similar non-free kernel modules).

As long as the kernel and ZFS are distributed not as a combined work but separately which the end-user has to combine themselves, then there is no derivative being distributed (the GPL's goal is not to prevent users from exercising their freedom to use software as they please, its goal is to prevent GPL code being distributed embedded in proprietary software)

BTW, debian also already has a zfs-fuse package which contains the CDDL zfs code plus dual-licensed GPL2 and CDDL packaging scripts. Debian also has a Debian GNU/kfreeBSD port which can have zfs natively without any licensing issues to work around (CDDL is compatible with BSD license, but not with GPL)

Other distros tend to care less about the niceties of adhering to licenses than debian does so may take some short-cuts - but my bet is that they'll do something very similar to the above to avoid giving Oracle any excuse for suing them.

I would like to point out that the goal of the people who wrote the GPL is to prevent users from using software as they please. They spread plenty of propaganda to try to sabotage those that do not agree with them. They even have a webpage that makes this perfectly clear:

Because this a port to linux and ZFS head (and what drives new feature/functionality) is released, stable and on targets Solaris.

Why ZFS? (1)

Gothmolly (148874) | 1 year,24 days | (#43314689)

What are the advantages of ZFS over, say, ext4? If you have a low-memory machine and not a lot of storage, does it buy you anything?

Re:Why ZFS? (2, Informative)

Anonymous Coward | 1 year,24 days | (#43314993)

Snapshots, volumes, checksums, easy expansion, better drive management, shorter recovery time when the system crashes, etc etc etc. ZFS is so far ahead of ext4 they are in completely different fields. ZFS works well on low resource machines too. I use it on a small home server with 512MB of RAM and it's been running great for over a year.

Re:Why ZFS? (1)

I get that - but why? Why is it worth the additional hassle?

Re:Why ZFS? (4, Insightful)

Guspaz (556486) | 1 year,24 days | (#43316117)

Better data integrity? Checksums on all blocks means the OS can tell if data is corrupt, and the data can be seamlessly recovered from redundancy (typically parity from raidz or raidz2, which also doesn't have the raid5 write hole because ZFS is copy-on-write).

Easier to use? zfs management happens through the "zfs" and "zpool" commands which are generally much easier to work with than obscure necromancy commands required for traditional types of systems that make me care about cylinders and partitions.

More flexible? The storage pool method, where you build a pool of capacity and allocate filesystems out of it, gives you a great deal of flexibility and simplicity. I just keep adding more storage to my pool as required, either by adding more RAID arrays or increasing the size of disks in those arrays, and then I've got my primary filesystem for storage, I've got a deduplicated one I use for backups, and I've got a compressed one I use for long-term archives. And creating a new one like that takes about five seconds without having to repartition or reformat anything. Creating/deleting filesystems is about as much effort as creating/deleting files.

Easier snapshots? Snapshots are instant on copy-on-write filesystems. Any modification of data causes the block to be copied anyhow, so all a snapshot has to do is not delete older blocks.

ZFS is one of a handful of next-gen filesystems (along with BTRFS and HAMMER) that are so far beyond traditional filesystems that it's a really eye-opening experience using them. That's not to say ZFS is perfect, or that the ZFSonLinux implementation is perfect, but it's in a reasonable state of stability at this point, and the advantages that these new filesystems offer is substantial.

I do wish that ZFS had asynchronous deduplication like HAMMER, though. ZFS deduplication requires atrocious amounts of RAM (estimates go from 5 to 20 gigabytes of RAM per terabyte of deduplicated data), while HAMMER has effectively no extra memory required at runtime for dedupe, because it just scans the disk afterwards and does the deduplication after the fact, so it doesn't need to hold the full block table in memory at all times.

Re:Why ZFS? (1)

smash (1351) | 1 year,24 days | (#43316561)

Async dedup is a trade off I guess. It means you need a window to run your dedup in where performance will no doubt suffer. If you are doing it inline you pay the memory or SSD cost to hold the dedup table, but don't need to worry about scheduling a maintenance window.

Great post!

It's worth pointing out that the latest versions of ZFS support LZ4 compression, which offer big improvements over LZJB and gzip. The illumos announcement does a great job of explaining the benefits: http://wiki.illumos.org/display/illumos/LZ4+Compression

It's so fast, especially on incompressible data, that I think it should *always* be enabled.

Here's a bit more information about it: http://code.google.com/p/lz4/

It's less hassle with a muti-disk setup than other forms of RAID but more hassle with one disk, especially on linux where you have to download the kernel modules separately.

Re:Why ZFS? (0)

Anonymous Coward | 1 year,24 days | (#43319705)

You haven't used ZFS, have you? There isn't additional hassle with ZFS, it's actually less hassle. ZFS doesn't require partitioning or formatting or putting new entries in the fstab file. File systems spreading over multiple disks doesn't require all that mucking about with LVM. You simply activate ZFS, hand it a device and it works, there is no hassle and it's much nicer than dealing with ext4.

Re:Why ZFS? (1)

TheRaven64 (641858) | 1 year,23 days | (#43323377)

I can't speak for Linux, but on FreeBSD it's no extra hassle. First, you don't need to think about partitioning, you just create a big zpool. You can restrict the size of filesystems within it, but they're not hard limits, so it's very easy to expand them. On the other hand, you do get the benefits of having different partitions (i.e. you can optimise them for different use cases, e.g. turning on compression and deduplication on a volume that you don't access much and turning them off in filesystems that require more speed).

Some things are just nice to have in the background, like the end-to-end checksums, so you can detect single-block corruption, and RAID-Z being aware of the structure of the filesystem (unlike RAID-5), so recovery time is proportional to the amount of data, not to the size of the disks. It can also easily take advantage of SSDs for acceleration. If you add SSDs as either cache or log devices then it will speed up reads or burst writes significantly, even if most of the pool is on spinning disks.

The biggest win for me is O(1) snapshots. You can snapshot a volume trivially and it has no performance impact (well, that's not quite true: some things become slower if you have tens of thousands of snapshots) and you can trivially roll back. The entire filesystem is copy-on-write. You can also clone a filesystem if you want to experiment. This is very useful for jails or VMs, where you can have a single filesystem with an up-to-date base install and then just clone it (constant time, takes under a second) to create a new clean VM.

Re:Why ZFS? (1)

dbIII (701233) | 1 year,24 days | (#43316139)

Huge - but mostly it's about the difference between LVM and ZFS in a multi-disk situation.
Snapshotting and portability is the biggest difference I can think of with ext4, everything else is pretty well comparing a LVM+ext4 bundle with zfs.

If you have a low-memory machine and not a lot of storage, does it buy you anything

I'd say not, ZFS is not something I'd run on a machine with less than 2GB.

Re:Why ZFS? (1)

smash (1351) | 1 year,24 days | (#43316527)

Lvm + ext4 does not do end to end checksums. KVM + ext4 does not make every write full-stripe.

Re:Why ZFS? (1)

smash (1351) | 1 year,24 days | (#43316551)

That's LVM of course. Typo... A major difference is that the file system is aware of the underlying backing store and can use that to its advantage, due to the "layering violation" stuff that some Linux developers decided was inherently bad and unacceptable.

Re:Why ZFS? (1)

TheRaven64 (641858) | 1 year,23 days | (#43323383)

I'd say not, ZFS is not something I'd run on a machine with less than 2GB.

It depends a lot on the size of the disk. The general rule of thumb for good performance with ZFS is 1GB of RAM for each TB of storage (more if you're doing dedup). I stuck ZFS (PC-BSD) on an old laptop I gave to my tango group to play music. It only had 1GB of RAM, but it only had 20GB of disk space, so it was completely fine, and it means that if they unplug it (the battery is dead) by accident without shutting down then they still have a consistent filesystem, and I could snapshot it in a known-good state that they could refer to if they broke everything.

ZFS Linux perhaps (1)

tyrione (134248) | 1 year,24 days | (#43316033)

But sure as hell doesn't mean ZFS like the twit who titled this thread as reaching an important 0.61 milestone. I'll pass on Linux with ZFS. I'll use FreeBSD where it is mature.

Re:ZFS Linux perhaps (1)

Guspaz (556486) | 1 year,24 days | (#43316151)

Consider that all three major ZFS platforms (Linux/FreeBSD/Illumos) are working on a common core that they all share, and that the lions share of ZFS development is coming from the Linux community. Perhaps the Linux ZFS community should not be dismissed so readily.

FreeBSD is a fantastic platform for ZFS, but considering that both FreeBSD and ZoL are pulling down new work all the time, it's not automatically more stable.
