FreeNAS 9.3 发布

      FreeNAS是一套免费的NAS服务器，它能将一部普通PC变成网络存储服务器。该软件基于FreeBSD，Samba 及PHP，支持CIFS (samba), FTP, NFS protocols, Software RAID (0,1,5) 及 web 界面的设定工具。用户可通过Windows、Macs、FTP、SSH 及网络文件系统 (NFS) 来访问存储服务器；FreeNAS可被安装于硬盘或移动介质USB Flash Disk上，所占空间不足 16MB。FreeNAS 服务器前途无量；它的开发工作十分活跃。单是2006年前4个月就释出11个修正版本。它是组建简单网络存储服务器的绝佳选择，免去安装整套Linux或 FreeBSD 的烦恼。

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.
