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.
