replication setup failure - [large block] null not allowed - setting replicate from scratch

[Brad T]

I've upgraded from FreeNAS 9.10 to 11.3 and switched some jails from warden to iocage.

I replicated the warden jails to another server previously and am now trying to recreate the replication to move the iocage jail datasets now instead.

All servers are running FreeNAS 11.3-U5.

source: freenas03.local: vol01/iocage/jails/network253
destination: freenas02.local: vol01/Backups-remote-vm/freenas03/jails/network253

I've tried legacy, ssh and ssh+netcat replication methods.

Naturally the snapshots are not the same, so I want to wipe the old snapshots and move forward with iocage-based snaps only.

When I kick off the replication task manually, I get this error:

No incremental base on dataset 'vol01/iocage/jails/network253' and replication from scratch is not allowed.

which makes sense of course.

When I go into the replication task configuration and check the "Replicate from scratch if incremental is not possible" option,

I get this:

[large block] null not allowed.

Detail:

Code:

    raise Error(self.name, 'null not allowed')
middlewared.schema.Error: [large_block] null not allowed

Keep in mind that the task was previously configured (so I assume there are no nulls in there!)

Any ideas or troubleshooting suggestions appreciated...

For bonus points and admiration... I have three servers so I am replicating the jail datasets on freenas03 to freenas01 and freenas02. I see that FreeNAS has created two additional snapshot tasks for each dataset/replication task... when there is already a top level recursive snapshot task for vol01/iocage. What the heck is going on? Why is FreeNAS proliferating (unnecessary?) snapshot tasks??!!

thanks... Brad

The [large block] error is a bug in 11.3u5, I'm sorry to say. It's patched waiting for next release.

In the interim, you can only delete then recreate a replication task, not edit it. Or you can install 11.3u4 (IIRC the bug came in with u4.1) and use that.

No bonus points for me - mine didn't create any snapshots by itself, but I went from 9 to 11.0 way back and that migration may have been better tested then.

thanks @JaimieV - I found several bugs in Jira after this post. Quite a mess. :(

Waiting impatiently for U6.

I think the extra snaps are a result of schedule/run automatically setting... but I’m not going to investigate further until the next update is released.

If you can't do anything with version and you need to change replication task without deleting and creating new one you can edit correct file by your own by this https://github.com/freenas/webui/pull/4730#issuecomment-734682179

Will there be a U6 after all?
