FreeNAS (And now TrueNAS CORE) Fans,

As mentioned in last weeks merge announcement, we had planned on very quickly making TrueNAS CORE 12.0 snapshot images available. I'm pleased to inform that the images have just gone live. Brave testers and developer-types can now upgrade from 11.3 by changing trains to "TrueNAS-12.0-Nightlies" in the upgrade UI, or install fresh from ISO images available below.

*CAUTION* These are nightly snapshots, not releases. Not for production use, danger, here be dragons, etc.

Nightly ISO:

Maybe add a nice popup in the UI for nightlies?

Let people enter:
"I Understand I Might Destroy EVERYTHING"

Even worse: Make it so it's an image and they can't cheat with ctrl-c ctrl-v...
Am I that evil? yes... Lawfully evil.

Lol, that would be a good idea. We do have the big "NOT for PRODUCTION use" scary warning right below the train though.

I think we all know of someone who thought... "Well, this isn't REALLY production..." before... well... "fun" happened...

We gave developers a PoC to toy with and two weeks later we could not switch it off because it was productive ...

But more on-topic: W00t!

And the special_small_blocks works per dataset! How cool is that? ;)

Update itself went without a hitch, mDNS announcements seem to be broken. Great work, folks!

Samba is running 4.12.0 with quite a few experimental changes. One of them is that it's using FreeBSD's POSIX AIO, which can be tuned via the relevant sysctls. A few other SMB changes:
- Share (not just filesystem) ACLs are also now exposed in the webui
- The NetBIOS name server is disabled by default (can be re-enabled under Network -> Global Configuration).
- There is GUI support for trusted domains in active directory (more comprehensive idmap editor).
- Everything related to libzfs is currently in a state of flux (expect random breakages for the time being).
- SMB shares now default to SA-based xattrs.

Special Allocation Classes are like a storages nerd's "special" dream...
So many things will change with ZFS... Besides performance, like being finally able to use deduplication without breaking the bank.
I think Team-IX is very happy with this for the lower-end of TrueNAS systems for some customers :)

Are we expected to do a inplace upgrade or reinstall completely from zero to have OpenZFS 2.0 and all other new features?

Normal upgrade is all you have to do. Once you are running 12 you will need to also do the zpool upgrade to enable those new features.

Thanks, I will use the nightly on the backup server of the backup server to understand all the news in the mean time. ;)

That prints "False" and exits, discovery by Bonjour on my Mac still not working. Not a big deal for a development snapshot.

Is the network up? Can you "# ping google.com" on the box?
Yep. I dunno why I get those errors. I checked up DNS, gateway, etc and still have them. Moreover SMB shares are unusable. Much better I rollback and wait some months to give it a try.

No worries. If you can send us a debug before you do that would be great, just so we can look at what may have happened in this instance. (And see if we can fix it for others)
