TrueNAS Core Replication to FreeNAS

[tomkhoo]

Hi,

Anyone know does TrueNAS Core able do replication to FreeNAS and vice versa?

This is in the 12.0U1 release notes:

Known Issues

Key	Summary	Workaround
NAS-107151	Replication fails between legacy TrueNAS 9.10 systems and 12.0-BETA1 systems.	Due to numerous improvements in the replication engine and ZFS, FreeNAS/TrueNAS 9.10 systems (or earlier) can no longer replicate to or from TrueNAS 12.0. Update the legacy TrueNAS system to FreeNAS/TrueNAS 11.3 or newer.

11.3 -> TrueNAS Core replication did not work for me when I put Core on my backup server for test. I switched both to Core - replication OK, but I was concerned that 12 wasn't "Redcoat ready", so switched both back to 11.3 until 12.1 was released.

I ended up in the same boat as @Redcoat but managed to get it working by configuring a PULL replication task instead of a PUSH one. I posted the details here.

Here's how I got a ZFS push replication scheme working from TrueNAS 12.0, using OpenZFS 2.0, on to FreeBSD 12.2, which is still on the older ZFS stack:

Replication between FreeNAS & TrueNAS machines (bare metal)

Hello all, Before I install TrueNAS on a separate machine and try replication from a FreeNAS machine to it, could anyone confirm if Replication works OK between the old and new? Many thanks, Chris

HTH!

Here are my notes about troubles I had with replication. I finally got it to work. I posted this so that others with similar issues might get to the end quicker. I set out use replication between FreeNAS-11.3-U4 and TrueNAS Core 13.0-U1.1. The FreeNAS is nearly full and I want to move the data over

using Replication. I could not get the FreeNAS to TrueNAS push to work so I tried a pull from the FREENAS box using the new TrueNAS box. I created the Snapshot of Dataset Vol1 on the Vol1 pool on FreeNAS then went to replication tasks on TrueNAS box. I was able to connect with the SSH and navigated to the "on a different system" to Vol1 pool. I selected the "on this system" for the Pool1/Data1 destination. I then ran the replication task. It does warn me that "0 snapshots found" on the source side of the GUI, I confirmed there is one on the FreeNAS system of Vol1. Even though I created one on the Freenas box. When I run the replication task I get an error that the snapshot cannot be found.
Then I realized that the filter field in finding the snapshot is always on. The default is "auto" so my "manual" snapshots were not seen. I fixed that. Now I get an error that says my target is busy. I had some things in the directory it complained that it would not overwrite them, so I deleted the couple of files. I did not understand what busy was? After some more work I found that busy is because I have a running Plex server in a Jail that is attached to that volume. Shutdown the Jail and viola the replication is happening. I hope this post helps someone. It is running a peak of 2GB/sec over my 10Gb link. Fixing that's for another day.

So replicate the directory before you give plex access to it.

Update: Data is now replicated on my Truenas server with Plex Plugin and I am streaming movies!
