这是一个振奋人心的版本,FreeNAS 9.3 基于 FreeBSD 9.3,我们认为它是 FreeNAS 的一个新里程,增加了许多新的功能,系统使用方面也有较大范围的变化。

需要特别注意的是,FreeNAS 9.3 仅支持 64 位处理器。而且 FreeNAS® 系统从 GPT 分区启动,主板 BIOS 必须支持 legacy BIOS 或 EFI。


  • FreeNAS 采用 ZFS 作为启动设备,支持选择一个或多个启动镜像设备,从而提升系统的可靠性。
  • 系统启动时,支持选择不同的启动环境,在管理界面中,可以创建、修改、删除和选择启动环境。
  • 采用 Grub2 作为启动引导程序。
  • 管理界面增加初始化向导,此项功能可以帮助新手快速完成 FreeNAS 全面的设置。
  • 不再提供 IMG 镜像(用于U盘安装),新版本 ISO 镜像不但可以用于刻录 CD 安装光盘,同时可以用于 U 盘引导安装。


  • 增加自动更新功能。
  • 系统更新界面可以自由选择各种系统版本。
  • 得益于采用了 ZFS 启动设备,可以在各版本系统之间回滚切换。


  • 新增 WebDAV 共享。
  • 更新 Samba 4.1.13。
  • 增加 NFSv4 支持, 包括 kerberized NFS。
  • Kernel iSCSI (CTL) 完全替代旧版本 iSCSI 代码,支持
    VMWare VAAI (all 7 primitives),MS ODX 和 Windows 2012 集群以及更高的性能和空间利用率。
  • iSCSI 支持关联 iSNS 服务器。
  • AFP 支持对每个共享设置允许访问主机和禁止访问主机。


  • AD / LDAP 配置文件实时验证。
  • 目录服务管理界面增加 Kerberos Realms 和 Keytabs 设置。
  • 目录服务基于 SSSD (System Security Services Daemon 系统安全服务进程) , 且通过 SSL/TLS 连接 LDAP 服务器。


  • 用户管理界面重新调整,更容易找到常用选项。
  • 新增 CA 和 Certificate 管理。
  • 合并所有系统变量调节选项,统一管理系统微调选项。

Release Notes for FreeNAS 9.3-RELEASE There are so many new features and enhancements in FreeNAS 9.3 that these release notes will break them into categories. In no particular order, FreeNAS 9.3-RELEASE offers the following improvements: [ Installation / Booting ] * FreeNAS now uses ZFS for the boot device(s), also supporting selection and mirroring of one or more boot devices for greater reliabilty. The features of ZFS are also utilized to provide cloned "boot environments" which allow the system to be rolled back (or even forked) to different OS versions. * A boot-time menu is provided for selecting and booting from a specific boot environment, a new system->boot UI allowing the user to create, rename, delete and select boot environments as well as running diagnostics on the boot pool and adding/replacing drives for it. * Both the installer and the installed system use the grub2 boot loader to provide boot menus and boot-time UI. * An install-time "Setup Wizard" is now provided to lead users who may be new to FreeNAS through the installation and setup process. Everything from the user's language, pool, shares, directory services, and initial settings can be set up through the Wizard. The Wizard is also careful to make no actual changes to the system until a final confirmation step, making it harmless to enter/exit the wizard at any time and simply explore its capabilities. * The ISO installation image can now be used both for USB booting or CD booting (the boot blocks allow for both usage scenarios), making a separate USB image unnecessary. [ Updating ] * While the old manual, monolithic installation and update system is still supported, the FreeNAS project has refactored its releases into cryptographically signed packages, provided both as "deltas" from previous release versions and as full packages, all of which are supplied from a secure update server. This server can be polled automatically (default: once per day), any available updates being downloaded automatically. When new updates have been downloaded, the user will receive an alert and be given the opportunity to apply them. * Updates are offered along multiple, parallel "trains" that the user can select from the Update UI. Older stable trains will offer minimal number of updates, more current trains will offer new features and a faster rate of change, and completely experimental trains with new, untested features under development will be offered to interested pre-release testers. * Any train can be selected at the user's discretion at any time, trains can be freely jumped between and, combined with the ZFS boot environment roll-back feature, the user can experiment with hosting multiple trains in parallel. * Using the new "install manifests" which allow this multi-train model to work, it is now possible to verify that your installed bits conform to what was originally installed (or last updated), making it possible to detect tampering or inadvertent corruption of the system. [ File sharing ] * WebDAV file sharing is now supported. * Samba upgraded to 4.1.13. * NFSv4 support added, including kerberized NFS. * Kernel iSCSI (CTL) has completely replaced the old iSCSI code, adding support for VMWare VAAI (all 7 primitives), MS ODX and Windows 2012 Clustering as well as much higher performance and space efficiency (zero'd blocks can now be reclaimed). Support for STUN and pool storage thresholds also makes VMWare behavior far more robust when ZFS pools fill up. * Kernel iSCSI sequently read performance has been sped up considerably by improving the way such read requests interact with ZFS * iSCSI nows supports associating to an iSNS server. * AFP now allows allowhosts and denyhosts per share. [ Directory Services ] * AD / LDAP configurations are validated immediately after input. * Kerberos Realms and Keytabs have joined the Direcory Services UI. * Directory Services now based on SSSD (System Security Services Daemon) and connections to LDAP servers done with SSL/TLS. [ User Interface ] * The much hated interface tabs are completely gone and the UI refactored to put most common UI options first, more esoteric options hidden behind Advanced modes. * Settings and Directory Services UIs completely revamped and streamlined. * Many hitherto difficult to discover features have been moved into their own sub-categories, new icons also being added where applicable. The tree menu and the top-level icons have also been synchronized. * New UI for CA and Certificate management. * All tunables have been merged - loader, sysctl and rc.conf variables can be managed from the same UI. [ Security ] * Software updates are cryptographically signed and validated, rendering the hashes unnecessary for anything but manual updates. * All passwords for services which have been associated with a FreeNAS/TrueNAS storage device (e.g. AD, LDAP, VMWare, etc) are encrypted in the database. [ Miscellaneous ] * Jail templates have been simplified and only optional templates are now listed. * Jails can now use DHCP to acquire their IPv4 configuration; they no longer require static IP configurations. * ZFS features added: Embedded Data feature flag, general performance improvements. * ZFS snapshots can now be coordinated with VMWare so that whenever a scheduled or manual snapshot is taken, snapshots of the VMs associated with the related datastore are first done, then the ZFS snapshot is taken. The temporary VMWare snapshots are then deleted on the VMWare side, so as not to impact performance, but still exist in the ZFS snapshot and can be used as "stable resurrection points" in that snapshot. These "coordinated snapshots" can be found (and are specifically marked as such) in the snapshot UI.
