Replication broken from 9.3 to 9.10

[fullspeed]

I upgraded the destination on my least important duo of Freenas boxes and replication has been broken since, closed by remote host.

Do I both sides need to be 9.10? if not is there a way to restart it without blowing it all away? I ask because ill eventually have to do my more important servers.

9.10 seems great otherwise.

I would suggest creating a bug report at bugs.freenas.org and posting the issue number here. To assist the devs in troubleshooting, include a debug which can be created using System -> Advanced -> Save Debug.

What cipher do you have configured? I think 9.10 lost the option for None.

Right, important little detail that's easy to miss.

If that is the case, opening the replication options menu and changing the cipher to an actual cipher. It's a pity for local networks, but most modern processors should still have little problem with "fast".

Ok setting it to fast worked, but I just lost literally half my replication speed, Why would this be taken away?

I have a Dell R510 with Xeon X5650 CPUs and 64GB of RAM so I have plenty of juice. This is very disappointing.

To quote JKH:

"Unfortunately, the SSH folks have removed support for the None cipher in later revisions so when we updated our ports, we lost that. We're going to create some other mechanism for "zero overhead replication" in 10 and then back-port it to 9.10, but that's not going to happen right away, so for now, just consider the None cipher dead and use one of the "cheaper" ciphers SSH offers. Sorry, but this one was just outside our control!"

Ok understood, I appreciate the response.

I was about to upgrade and split out all my Freenas servers, going from four to eight. If replication ends up being this slow I might have to scrap it all together and look at other products.

For 98% of people it wouldn't make a difference but I've moved 4 petabytes of data this year through my two largest, losing half my speed would render replication unusable :(

Stay on 9.3 till they backport the zero-overhead cipher to 9.10. You're not loosing anything by waiting.

ok fair enough, I'm glad I caught this early.

I'll install 9.3 on all new servers.

Thanks again

+1 for 'None', use this all the time locally...

I believe the latest version of 9.10 supports this again, I'll be looking to test this shortly (and FreeNAS 10 potentially).

I don't think so as the U2 docs still show Standard or Fast for the Encryption Cipher. If it is back let us know as we missed it and will add it back into the docs.

As for 10, be forewarned that it uses a totally different replication design that only supports replication to another Corral system. In other words, you can't replicate to a non-Corral system by design.

It's certainly present in the drop-down menu:

I'll try it out and see how it goes.

Thanks for checking! I'll add it to the doc team's queue.
