FreeNAS 8.3.0-BETA1 is now available

The FreeNAS development team has announced the availability of FreeNAS 8.3.0-BETA1.  This is the first public release of the 8.3.0 branch of FreeNAS, which upgrades the underlying base system of FreeNAS to FreeBSD 8.3-RELEASE-p7. This update brings with it version 28 of the ZFS filesystem, as well as a number of updates to the drivers and utilities in the base system.

FreeNAS 8.2.0 brought with it the ability to install plugins, this functionality is present in FreeNAS 8.3.0 as well.  At the moment upgrading the plugin jail to the version included with FreeNAS 8.3.0-BETA1 will cause plugins to stop working and will require re-installation and reconfiguration of all plugins to resume normal operation.  It is recommended to avoid upgrading working components of the plugin system.

ZFS v28 includes several features such as the ability to detach a dedicated ZIL device, triple parity RAIDZ, and deduplication.  There are numerous caveats to using deduplication, please do some research into the possible caveats of using dedup before enabling it.

Take Note, upgrading an existing ZFS pool is a one way street, once the upgrade is done it is not possible to use older versions of FreeNAS, nor is it possible to downgrade your pool.  This upgrade can be done by running zpool upgrade from the CLI, it is not done automatically via the upgrader, nor is there a way to do the upgrade from the GUI.

FreeNAS 8.3.0-BETA1 can be downloaded from this location this location.

FreeNAS is shaping up to become one of the best, free NAS operating systems

Tarsnap article and paypal payments

Tarsnap is an online service where you can securely backup your data. It is maintained by Colin Percifal, an ex FreeBSD Security Officer.

Tarsnap is a secure online backup service for BSD, Linux, OS X, Minix, Solaris, Cygwin, and probably many other UNIX-like operating systems. The Tarsnap client code provides a flexible and powerful command-line interface which can be used directly or via shell scripts.

Linux Journal has a 10 page article on Tarsnap in its latest issue.

Collin recently announced you can now pay by credit card for the Tarsnap service, in addition to Paypal.

FreeBSD Supported on Windows Server Hyper-V via Beta Release

Microsoft and collaborators today announced a beta release of drivers that enable the open source FreeBSD 8.2 server operating system to run in a virtual machine (VM) using Microsoft’s Hyper-V Server.

The beta, which isn’t intended for use in production environments, can be downloaded from the GitHub portal here. Installation instructions can be accessed on this page. The code was released under a FreeBSD license.

In the near future, GitHub will supply ISO images of FreeBSD that will include the new drivers. The collaboration, which involved Microsoft, Insight Global, Citrix and NetApp, was highlighted at the BSDCan 2012 event in May.

Gnome3 porting to FreeBSD

Personally I don’t like Gnome (2) and Gnome3 even less. There’s good news for those who are waiting for Gnome3 on FreeBSD: Gnome3 porting to FreeBSD.

Gnome3 isn’t working on FreeBSD as Gnome3 uses technologies that are not available to BSDs. I thought Gnome3 to BSD was a dead project till Juanjo Marin (Gnome Dev in Evince and A11y) mentioned a few things about BSD in Gnome’s Marketing ML.

FreeBSD Security Advisory (Bind)

The FreeBSD Security Team has identified an issue in Bind and has issued the following security advisory: FreeBSD-SA-12:05.bind.asc (06/08/2012).
I. Background

BIND 9 is an implementation of the Domain Name System (DNS) protocols. The named(8) daemon is an Internet Domain Name Server.

DNS Security Extensions (DNSSEC) provides data integrity, origin authentication and authenticated denial of existence to resolvers.

II. Problem Description

BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broken chain of trust. Under high query loads, when DNSSEC validation is active, it is possible for a condition to arise in which data from this cache of failing queries could be used before it was fully initialized, triggering an assertion failure.

III. Impact

A remote attacker that is able to generate high volume of DNSSEC validation enabled queries can trigger the assertion failure that causes it to crash, resulting in a denial of service.

For a workaround and solution, check out the security advisory: FreeBSD-SA-12:05.bind.asc

August BSD Mag: Tuning ZFS on FreeBSD and Set up a VPN Server

The August issue of BSD Magazine is out: Tuning ZFS on FreeBSD.

Tuning ZFS on FreeBSD
By Martin Matuska

ZFS is a modern 128-bit file system based on the copy-on-write model. It originates from the OpenSolaris project and has first appeared in FreeBSD in 2008. ZFS has many innovative features including an integrated volume manager with mirroring and RAID capabilities, data checksumming and compression, writable snapshots that can be transferred between systems and many more. In this article the author is going to discuss several tuning options including sysctl(2) knobs and give examples how can ZFS performance and efficiency can be measured and evaluated. This article is intended for FreeBSD users with ZFS version 28 available since 8.3-RELEASE and 9.0-RELEASE.
