Native ZFS for Linux

Oboy. http://github.com/behlendorf/zfs

Wow! Didn't think a native ZFS would ever be available on Linux. Lot's of info on the wiki page:

Give this a spin, cant wait for btrfs!

fuse ZFS is old news and frankly it doesn't interest me much. ZFS rocks but using fuse to get it working with Linux seems like overkill. Wait for btrfs to mature or use FreeBSD or {Open}Solaris.

OK so I didn't read the article,

If I understood correctly, this isn't based on FUSE, it's a native kernel module.

paldepind · 2010-06-06 11:22:50

I thought the ZFSs (Sun CDDL) license were incompatible with GPL? How can this be?

Ramses de Norre · 2010-06-06 11:26:27

Read the FAQ, the CDDL implies that the zfs kernel module cannot be distributed as part of GPL software (the kernel) but apparently there is no problem with just providing the code that can be compiled on a linux system as a kernel module.

Well I hope this guy knows what he's doing, if it were me I'd want to stay away from that whole legal minefield just in case. Especially since CDDL was clearly authored with the intent of keeping the Solaris USPs from being copy-pasted into Linux. Still, this would have been quite an interesting project a few years ago but IMO the progress of btrfs and the inability to integrate this with the mainline kernel make it little more than a curiosity.

sand_man · 2010-06-07 01:05:54

It should be legal. All he is doing is modifying code so that it works with the Linux kernel but still releasing the source under the CDDL.

This ZFS on Linux port was produced at the Lawrence Livermore National Laboratory (LLNL) under Contract No. DE-AC52-07NA27344 (Contract 44) between the U.S. Department of Energy (DOE) and Lawrence Livermore National Security, LLC (LLNS) for the operation of LLNL. It has been approved for release under LLNL-CODE-403049.

US Govt vs. Sun/Oracle?

Wow this sounds pretty awesome. I have an opensolaris file server setup just so i could use ZFS, but I hate using opensolaris....

So who's a lawyer? Can a distribution make a binary package of this? If not can a distribution setup an AUR like repo containing it and making it easy to compile and install with automated tools?

I think that's where it gets a little sticky and I bet most distributions wouldn't even bother touching it.

BTW: I love OpenSolaris.

Confusing. I've installed OSOL in my virtualbox to play with ZFS. Now I read this http://wiki.github.com/behlendorf/zfs/example-zvol and they format as ext2??
As far as I know ZFS IS the filesystem, what is ext2 doing there?

IANAL, but AFAIK binary packages are out because it's a kernel module. As soon as it's binary, it's considered a Derivative Work and therefore illegal to distribute since the Kernel Licence (GPL) can not be satisfied.

A script to install it (eg a PKGBUILD in AUR) is completely independent and has no requirement to fulful the license terms of the Kernel or the CDDL in and of itself.

But again, IANAL

It looks to me they just have the volume management part working here, not the whole filesystem. In other words they provide an alternative to raid/lvm. at least thats how I understand the example given on their page

I hope it didn't give you too many false-results

They did it to be able to run lustre on top of it.

That's the reason they haven't done the zfs posix layer yet (which means zfs volumes can't be mounted). But they are working on it.

Hi guys,

it seems this project is NOT using FUSE anymore.

it would be interesting to see a package in AUR for trying it out with ArchLinux

http://github.com/behlendorf/zfs/wiki

anyone tried it already?

The FUSE project and this one are two separate animals. This one is:

- unfinished
- built to run on 2.6.32
- requires a solaris emulation layer written by the same author

I wasn't able to get the emulation layer compiled even on kernel26-lts. It seemed tailored for RedHat (or perhaps it was Debian). Quickly lost interest.

I've tried making PKGBUILD's. And spl build and installs fine, but I get a building error on zfs:

I don't know what this error is. Could it be a bug in gcc?

It will only build on 2.6.32.

jerryluc · 2010-09-23 06:21:20

Are you sure? i've been in contact with the developer and he did'nt say anything about that.
