FreeNAS® 9.2.0 fixes this list of bugs and introduces the following features:

  • The kernel UMA allocator is now the default for ZFS. This results in higher ZFS performance.
  • By default, FreeNAS® now treats all disks as 4K sector, also known as advanced format, disks. This is a future-proof setting that allows advanced format disks to be used as replacement drives for older, legacy 512 byte sector drives without compromising performance. An alert will automatically be created for pools that are not 4K-aligned.
  • GELI improvements mean that there should be virtually no performance impact when volume encryption is enabled, if the CPU supports AES-NI.
  • The kernel modules for FreeBSD's five new TCP congestion control algorithms have been added. These must be configured from the command line and are meant for advanced users and researchers who wish to experiment in pushing network throughput using the new algorithms.
  • USB 3.0 support is disabled by default as it currently is not compatible with some hardware, including Haswell (Lynx point) chipsets. To enable USB 3.0 support, create a Tunable named xhci_load, set its value to YES, and reboot the system.
  • Avahi, also known as multicast DNS or Bonjour, is now used to register all services, including the web service. This means that you no longer need to have a monitor attached to the system to know its initial IP address, if the system your browser is running on supports mDNS. freenas.local is the default hostname, unless their are multiple FreeNAS® systems in the network, in which case the default hostname is freenas-n.local, where n is the number of that system. It also means that only one server now appears to Mac OS X Finder. If the system has AFP shares, Finder will not display any CIFS shares. This is different from 9.1 which showed one server per protocol in Finder.
  • FreeNAS® no longer sends daily emails containing the security run output and instead only sends an email when there is an error condition, assuming that the email settings have been configured in System → Settings → Email.
  • The built-in admin user account is no longer used and Account → Admin Account has been removed. The first time the FreeNAS® graphical interface is accessed, a pop-up menu will prompt for the root password. Subsequent logins to the graphical interface will require this password.
  • The "Permit Sudo" field has been added to the add and edit screens for Users and Groups.
  • Add a column to View Groups and to View Users to indicate whether or not "Permit Sudo" has been set.
  • HTTP and HTTPS access to the FreeNAS® graphical interface are no longer mutually exclusive. The fields "WebGUI HTTP Port" and "WebGUI HTTPS Port" have been added to System → Settings → General.
  • A "Enable automatic upload of kernel crash dumps" checkbox has been added to System → Settings → Advanced.
  • The "Record Size" field in Create ZFS Dataset is now a drop-down menu of allowed values.
  • The View Disks screen now shows the size of the disks.
  • Netatalk has been updated to version 3.1.0. See its Release Notes for a list of changes in this release. The Add Apple (AFP) Share menu has been simplified and a "Default umask" option has been added.
  • The "Server Name" field has been removed from AFP. In Netatalk 3, this value is automatically derived from the system hostname.
  • Add the "Enable home directories" and "Home directories" options to AFP.
  • The AIO options have been removed from CIFS.
  • The "NetBIOS Name" field in the Active Directory and CIFS screens now auto-populate with the FreeNAS® hostname. The documentation now warns users against changing these defaults as doing so may break AD or CIFS integration.
  • Fourteen TLS-related fields have been added to the Advanced Mode of FTP.
  • The "Bind IP Addresses" field in NFS now provides the list of valid IP addresses to select. If no address is selected, NFS will bind to (all interfaces).
  • Plugins now offer in-place updates. An update button will be displayed when a newer version of an installed plugin becomes available.
  • A jails templating system has been added, allowing the quick deployment of new jails from existing templates and the ability to create custom templates.
  • Linux jail support has been added and installation templates are included for Debian-7.1.0, Gentoo-20130820, Ubuntu-13.04, Suse-12.3, and Centos-6.4.
  • An "IPv4 Address" column has been added to the View Jails screen.
  • A shell button has been added to Jails, making it easy to access the command line of the selected jail.
  • A "Create directory" checkbox has been added to the Add Storage function of a jail so that the user does not have to first access the jail's shell to make sure that the directory already exists. A "Read-Only" checkbox has also been added to this screen.
  • A link to the online FreeBSD manual pages has been added to Help.
  • Added bxe(4) driver for Broadcom NetXtreme II Ethernet 10Gb PCIe adapter.
  • Added padlock(4) driver which provides cryptographic hardware acceleration for VIA C3, C7 and Eden processors.
  • A complete reST API has been created, allowing a FreeNAS® instance to be controlled remotely. See examples/api for some examples and Using the FreeNAS® API for instructions on using the API docs.
