ZFS support in FreeBSD


Quote:
I'm happy to inform that the ZFS file system is now part of the FreeBSD
operating system. ZFS is available in the HEAD branch and will be
available in FreeBSD 7.0-RELEASE as an experimental feature.

ZFS is very different from any other file system ever made, its truely innovative and revolutionary.

Wikipedia article: http://en.wikipedia.org/wiki/Zfs

Would you recommend ZFS for a file server, workstation, compute server?

It is native (kernel) support. Userland only support has just be announced for Linux (FUSE).

I would recommend ZFS for any use provided it is technically possible.

I believe the number of patents is 56.
That doesn't hurt its use in FreeBSD and other O/Ses given the CDDL license is preserved.

From http://blogs.sun.com/Gregp/entry/are...patents_useful

We will *never* (yes, I said *never*) sue anyone who uses our ZFS codebase and follows the terms of the license: they publish their improvements, propagate the license, and not sue anyone else who uses the ZFS codebase. And look at the innovation not only with ZFS in OpenSolaris, but its adoption by Mac OS X and BSD.

Or even the GPLv3...
Its probably not going to happen...but its been discussed by Jonathan Schwartz

If Solaris goes over to the GPL3, what position would apple and freeBSD be in, i doubt the BSD license is compatible with the GPL3, so would that not cause licensing problems for freeBSD? Im still in limbo about GPL->BSD ports, could someone maybe explain?

If Solaris goes the GPLv3 way, that would certainly be as a dual license along the CDDL so there should be no clash with the BSD license.

Indeed, I think that Mr. Schwartz mentioned something to that effect in his blog. Makes sense...

ZFS no fuse linux

well, this is all well and good - i see why kernel.org can't put out native zfs for the interim, but that shouldn't be the end of it - has anyone been developing zfs kernel support that you could compile into a kernel for zfs? The fact that the gpl is inconsistent with sun is infinging on my freedom to compute - seems contradictory to Stallman's philosophy for GNU. So anyway - does anyone know of anyone who is developing such a source code?

The GPL isn't inconsistent with Sun. Sun is already releasing code under the GPL, including Java and the LGPL, OpenOffice.
The CDDL make no restriction on license mixing so if your freedom is infringed, the issue is on the GPL side.

The CDDL is OSI compliant.

No, but a read-only driver wouldn't be that hard, given the fact OpenSolaris has released code allowing to mount, open and read ZFS under the GPLv2 in its grub extensions.
