Replicated dataset inaccessible

I have set up replication between 2 truenas 25.04 systems. The replication succeeded, but I cannot access the replicated dataset?

The replication task:


admin account settings:

SSH+Keypair is set up, connecting through Tailscale.

The real troubles show at the remote system, when I click the dataset I replicated, I get the error message: [Errno 5] Input/output error

I am unable to delete the dataset, the CLI also shows weird stuff:

root@truenas[/mnt/NAS]# ll
ls: cannot access 'Videobanden': Input/output error
total 13
drwxr-xr-x 4 root  4 May 18 15:53 ./
drwxr-xr-x 4 root  4 May 17 05:39 ../
d????????? ? ?     ?            ? Videobanden/
drwxrwx--- 8 admin 8 Jul 25  2024 backup/

chown/mhmod give me the same errors.

How can I fix this? It did replicate, but seemingly with wrong permissions?

In the web UI? Just clicking it spits out an error?


Do you want to delete it?


Which “user” ran the Replication Task? You didn’t use “sudo”. Who is the SSH connection “videobanden” configured for? The UID 950 “admin”?


Why did you select two datasets in the source? How come you did not only select the dataset “NAS”?

Was your intention to replicate “NAS” → “NAS”?

By selecting multiple source datasets in the GUI, you’re telling the Replication Task to nest them underneath the target.

yeah:

I don’t want to delete it, I was checking if that’s possible because nothing else is.

which user? Admin? Where can I see this? I used my admin account to set it up.

I didnt use sudo, do you mean this option?

SSH Connection is set up with root:

I selected 2 datasets by mistake, I just want the videobanden dataset to replicate.

Things can sometimes look weird if replication is still running. Are you sure it’s complete?

Yeah, the size of the dataset is identical on both systems.

What is the current layout of datasets on either end?

zfs list -t filesystem -r <poolname>

Mounts as well, especially on the target server:

zfs mount

Looks normal.

Can you check the target’s “videobanden” dataset permissions in the GUI or does it error?

What about:

stat /mnt/NAS/Videobanden

nfs4xdr_getfacl /mnt/NAS/Videobanden

On the Destination NAS it hits me immediately with the error:

stat: cannot statx '/mnt/NAS/Videobanden': Input/output error

nfs4xdr_getfacl: Failed to get NFSv4 ACL```

I’m out of ideas. Either something is broken or this is a bug.

@awalkerix does this look like a permissions issue to you?

@robuust is it possible to boot from a live Linux ISO to attempt to at least view or access the files within the dataset?

The pool can be imported readonly to assure you do not modify anything.

How often are your snapshots and replication running? Daily, hourly etc?

Weekly, every Sunday.

I’m on location once a week, maybe Thursday again. Good call, I’ll check if that works!
