zfs discuss - Apr 2007 - ZFS committed to the FreeBSD base.

Hi.

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.

Commit log:

  Please welcome ZFS - The last word in file systems.
  
  ZFS file system was ported from OpenSolaris operating system. The code
  in under CDDL license.
  
  I''d like to thank all SUN developers that created this great piece of
  software.
  
  Supported by:	Wheel LTD (http://www.wheel.pl/)
  Supported by:	The FreeBSD Foundation (http://www.freebsdfoundation.org/)
  Supported by:	Sentex (http://www.sentex.net/)

Limitations.

  Currently ZFS is only compiled as kernel module and is only available
  for i386 architecture. Amd64 should be available very soon, the other
  archs will come later, as we implement needed atomic operations.

Missing functionality.

  - We don''t have iSCSI target daemon in the tree, so sharing ZVOLs via
    iSCSI is also not supported at this point. This should be fixed in
    the future, we may also add support for sharing ZVOLs over ggate.
  - There is no support for ACLs and extended attributes.
  - There is no support for booting off of ZFS file system.

Other than that, ZFS should be fully-functional.

Enjoy!

Wow! This is great news Pawel, and quite impressive. I know I can
safely speak for others when I say that the work you''ve done and your
participation in the community is much appreciated!

Hi Pawel,

Congratulations, nice work! :)

I''m interested in the cross-platform portability of ZFS pools, so I
have
one question: did you implement the Solaris ZFS whole-disk support
(specifically, the creation and recognition of the EFI/GPT label)?

Unfortunately some tools in Linux (parted and cfdisk) have trouble
recognizing the EFI partition created by ZFS/Solaris..

This is fantastic news!  At the risk of raking over ye olde arguments,
as the old saying goes: "Dual licensing?  We don''t need no
stinkeen
dual licensing!".  :-)

Well done, team!  Everyone who cares about their data will be happy :-)

Great news, Pawel!
Waiting to test it :)

I''m not yet setup to move disks between FreeBSD and Solaris, but my
first goal was to integrate it with FreeBSD''s GEOM framework.

We support cache flushing operations on any GEOM provider (disk,
partition, slice, anything disk-like), so bascially currently I treat
everything as a whole disk (because I simply can), but don''t do any
EFI/GPT labeling. I''ll try to move data from Solaris'' disk to
FreeBSD
and see what happen.

First try:

GEOM: ad6: corrupt or invalid GPT detected.
GEOM: ad6: GPT rejected -- may not be recoverable.

Actually, you might want to run that statement by a certain John Birrell
(jhb at FreeBSD.org) regarding the DTrace port and see what answer you get.

It is planned, but it''s not trivial. Does samba support NFSv4-style
ACLs?

Did you use my previous patches? There is no cddl/lib/libumem/umem.c is
HEAD, it was it''s old location and it was moved to
compat/opensolaris/lib/libumem/. Delete your entire cddl/ directory and
recsup.

Great work, Pawel!  This is an important milestone for the
FreeBSD project.

Just a quick question:  Does ZFS still work reliable when
the write cache for ATA disks is enabled, i.e. with the
line "hw.ata.wc=1" in /boot/loader.conf?

I can''t wait to set up a test machine with FreeBSD -current
to start playing with ZFS.  :)

Best regards
   Oliver
