Release Notes for FreeNAS 9.1.0-RELEASE
1) Synced with version 9.1-STABLE of FreeBSD for many performance improvements,
bug fixes, and updated software packages.
2) Many improvements to the ZFS filesystem, including feature flags,
TRIM support, enhanced drive removal notification, LZ4 compression,
improved ARC memory reclamation and reliability improvements.
3) New Plugin management interface, with support for direct uploading and
easy browsing and installation of plugins from a central FreeNAS plugin repository.
4) Improved Jail subsystem with support for multiple jails and an enhanced
UI including enhancements from PC-BSD's Warden.
5) Improved Volume manager, including auto optimization of volumes
for performance.
6) Improvements to the encryption subsystem.
7) Documentation enhancements.
8) **IMPORTANT** Backward compatibility of FreeNAS 9.1 ZFS pools
with older versions of ZFS is not to be expected. Upgrade pools
with extreme caution, as all ZFS pool upgrades are one-way and only
FreeNAS 9.1, FreeBSD 9-STABLE, and FreeBSD 8.4 currently support
this ZFS pool format.
9) To convert 8.* pluginjail to a 9.* pluginjail, please run the
jail migration script like so (prior to configuring jails) from the
command-line:
/root/migrate_pluginjail.sh -D
Any installed 8.x plugins will need to be updated manually.
10) There is a GUI image to upgrade older installations of FreeNAS
from version 8.0.1 through 8.0.4p3, the names of those files are:
FreeNAS-9.1.0-RELEASE-x64.8_0_x_LEGACY_GUI_Upgrade.xz
FreeNAS-9.1.0-RELEASE-x86.8_0_x_LEGACY_GUI_Upgrade.xz
for amd64 and i386 platforms respectively.
========================
Release Notes for FreeNAS 8.3.1-RELEASE-p2
*** IMPORTANT ***
- FreeNAS 8.3.0-BETA1 has the FreeBSD base system switched to FreeBSD
8.3-RELEASE-p3. The most noticable affect of this change is the
inclusion of ZFS version 28, but there are a number of other driver
changes as well.
- The mps driver for 6gbps LSI SAS HBAs is version 13, which requires
phase 13 firmware on the controller. This is a hard requirement,
running older firmware can cause many woes, including the failure to
probe all of the attached disks, which can lead to degraded or
unavailable arrays.
************************************************************************
- ZFS v28 includes deduplication, which can be enabled at the dataset
level. The more data you write to a deduplicated volume the more
memory it requires, and there is no upper bound on this. When the
system starts storing the dedup tables on disk because they no longer
fit in RAM, performance craters. There is no way to undedup data once
it is deduplicated, simply switching dedup off has NO AFFECT on the
existing data. Furthermore, importing an unclean pool can require
between 3-5GB of RAM per TB of deduped data, and if the system doesn't
have the needed RAM it will panic, with the only solution being adding
more RAM or recreating the pool. Think carefully before enabling
dedup! Then after thinking about it use compression instead.
************************************************************************
- There is no need to upgrade your plugin jail or plugins if you are upgrading
from FreeNAS 8.2.0-RELEASE-p1. If you do upgrade the plugin jail the plugins
installed in that jail may be lost.
- The GUI upgrade format changed in 8.2.0-BETA3 from xz to txz. What
this means is that if you are attempting to do a GUI upgrade to
8.3.0-RELEASE from 8.2.0-BETA3 or later use the .txz version of the
GUI_Upgrade file. If you are upgrading from any previous version use
the .xz file.
- The image size increased in 8.0.1-BETA3. The new size requires a 2 GB
storage device. The GUI upgrade can be used to upgrade a system from
8.0.1-BETA3or later but upgrades from earlier releases than
8.0.1-BETA3 can only be done from the CD. The other option is to save
the config, reinstall the new version, then restore the config.
- FreeBSD can be really touchy with hardware. Please be sure to update
your BIOS/BMC firmware when upgrading / installing FreeNAS if you run
into OS hang issues. There have been cases identified where a BIOS
upgrade has fixed driver hangs, and/or other issues with FreeNAS; one
such example was with an Intel 82578DC motherboard, as noted in the
FreeNAS 8 forum thread titled "8.0.3-RELEASE coming soon..":
http://bit.ly/rq78Q3 , post # 70-88. Again, please only do this if you
experience booting / runtime issues, as some vendors don't test
FreeBSD interoperability as much as others between major firmware
releases.
- Previous builds were branded as i386/amd64 (32-bit and 64-bit
respectively). 8.0.3-RC1+ rebranded the architectures as x86 and x64,
respectively.
- 8.0.1 and 8.0.2 images advertised CIFS shares to Macs by default but
8.0.3 and later images don't advertise CIFS shares by default. If you
want to advertise CIFS shares in 8.0.3 and later, be sure to turn on
"Zeroconf" support in the CIFS global settings.
- Builds prior to 8.0.3-RELEASE with 'CIFS' didn't actually have AIO
(asynchronous I/O) enabled. So, if you experience performance
degradation after upgrading from prior versions of FreeNAS to
8.0.3-RELEASE or newer, turn off AIO or tune the AIO size from '1' to
something more reasonable (the new default in 8.0.3-RELEASE-p1 is 4096
or 4kB).
Changes in the 8.3 branch versus 8.0.x
Overview ========================
The 8.3 branch of FreeNAS introduces many functional changes when
compared with the 8.0.x releases.
ZFS can be manipulated from the CLI, and changes for supported items
tracked by FreeNAS will be reflected in the GUI. zvols, datasets, and
entire volumes can be created, destroyed, or manipulated on the CLI and
will be propagated to the GUI.
The GUI now supports active-passive multipath capable hardware, which
targets mainly SAS drives on dual expander backplanes. Any multipath
capable devices that are detected will be placed in multipath units
which are then exposed to the GUI, and the parent devices will be
hidden.
Plugins are now available. Third party modules can be added to FreeNAS
which will persist across upgrades and can be manipulated and configured
from the GUI. Documentation on using and creating plugins is available
at http://doc.freenas.org/index.php/Plugins . BitTorrent, DLNA/uPNP, and
iTunes plugins are available as of this writing.
The GUI now includes a webshell, which allows you to access a root shell
from within a web browser.
The "Create Volume" modal was renamed to "Volume Manager". Extending
existing pools is more intuitive than it was previously; selecting
multiple disks for a storage volume is now done via a multiselect widget
instead of checkboxes to improve ease of use when creating volumes.
ZFS volumes now have periodic scrub tasks configured for them; the
default is set to 35 days to be consistent with the OS default.
An autotuning script is now available -- disabled by default. It sets
various tunables and sysctls based on system resources and components.
The predetermined values are exposed through the GUI from the Sysctls
and Tunables panes.
A newer web toolkit is used, which behaves better with modal dialogs and
more intuitively in general when compared with older versions. It also
has better browser compatibility, including compatibility with Android /
iOS mobile devices!
A more responsive service state detection mechanism was added to improve
FreeNAS interoperability in VM software (VMware, VirtualBox, etc).
Errata
========================
Encrypting a volume implies forcing a 4K block size. This is enforced by
the GUI. However, clicking the encrypt volume checkbox then unchecking it
will leave the Force 4K checkbox checked, which is not the default.
The plugin jail networking has been switched to VIMAGE, which requires
bridging the plugin jail with an external interface. On systems with
multiple interfaces there is currently no way to specify which interface
is used. The current system chooses the interface with the default
route.
The plugin jail currently doesn't work properly if the external interface is
a vlan pseudo-device.

2. Remove SVN revision checker from downgrade script. This
is pointless in a git universe.
3. Fix a kernel panic when the plugin jail is used with a
lagg interface.
4. Remove testdisk from the image. It's a great tool, but the distfile
keeps getting rerolled which breaks the build.

where the default monthly scrub wasn't running. It's recommended to check
the scrub schedule and be aware of it's impact on FreeNAS.
4. Disable the ZFS encryption option when extending a volume. The system will
automatically match the encrrption state of the existing pool.
