FreeNAS 8.3.1-BETA3 is Available

Written by admin on .

The FreeNAS development team is pleased to announce the availability of FreeNAS 8.3.1-BETA3. This is the last planned public beta of 8.3.1 as it moves towards the final.

FreeNAS 8.3.1-BETA3 can be downloaded from the following location:

FreeNAS 8.3.1 adds ZFS volume encryption to the features available in FreeNAS 8.3.0. BETA3 has a number of bug fixes and feature requests based on community feedback and testing of the first two beta releases, as well as feedback and bug fixes from FreeNAS 8.3.0-RELEASE-p1.

There are no further betas planned as FreeNAS 8.3.1 marches towards the final release. At this point there will be no additional features added to 8.3.1.

Virtio drivers have been added to the image. For this BETA they default to off, which makes them a bit difficult to use.

FreeNAS 8.3.1-BETA2 is Available

Josh has announced the availability of the FreeNAS 8.3.1-BETA2 images to Sourceforge:

Things went fairly well in the first beta and I’m shooting for 8.3.1-R by the end of the month, so here’s another BETA to give things a spin. At this point things are looking to be in good shape, I’m calling this a BETA because I’m very conservative, and because encryption can go wrong in such grand fashion. I’d rather this image wasn’t used for critical or production use. Make sure to have backups!

That being said we have no reports of anyone losing data because of bugs in the encryption code, nor have we had any issues with it in our internal testing. (4 months give or take). If you find any bugs in this BETA, please report them to


  1. Add a feature to initialize disks with random data.
  2. Add the iconv option to rsync.


  1. Fix a bug that was preventing multiple destination address for SMART from working.
  2. Create an empty /var/db/pkg to silence warnings from the SNMP service.
  3. Fix a bug that was preventing the default scrubs from running. ZFS scrubs are very I/O intensive, and this update will fix many instances 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 encryption state of the existing pool.
  5. Commit changes to ataidle immediately rather than requiring a reboot.
  6. Fix a bug that prevented creation of RAIDZ volumes.
  7. Fix a bug that prevented stopping the CIFS service.

FreeNAS 8.3.1 Beta 1 is Available

Written by admin on .

The images for FreeNAS 8.3.1-BETA1 are available on sourceforge.

This is a BETA! I am very emphatic about this because this is the first image available with ZFS volume encryption. Up to this point we’ve been pretty good about preserving ZFS volumes, not matter what happens to the OS or configuration.

With this image all bets are off. When encryption goes wrong it usually takes your data with it.

This image is a BETA, it is not suitable for production use, it is not suitable to put data on that you care about even if you are NOT using the encryption functions.

There’s no way to migrate an unencrypted volume to encrypted or vice-versa.

If your processor supports the AES-NI instruction set you should see very little if any degradation in performance when using encryption.

Aside from the encryption, the iscsi target was updated, so target reloading needs testing, and samba was updated, so shadow copies needs testing.

See the release notes for a complete list of changes.

The docs and screenshots for this should be updated by next week.
