sub dataset isn't separated from the father dataset on the client

[mosh]

Hi,
Recently i created a new dataset on an existing dataset on my FreeNAS server.
I did it in order to be able to take snapshots of a single directory, instead of the whole thing.

Original dataset: /nfs/dataset1
I've created in FreeNAS GUI: /nfs/dataset1/dataset2
afterwards i could see that a new directory named 'dataset2' was created at the root of dataset1.
I copied data into it. however i do not see the data is filling the new dataset (dataset2). it is still part of the top dataset (dataset1).

It looks, from the clientside that the new dataset2 isn't really pointing to the new dataset, instead to a normal directory (with the same name as dataset2) on dataset1.

from a client:
$ du -hc /mnt/dataset1/dataset2
104G

On the freeNAS Server:
$ df -h
Filesystem Size Used Avail Capacity Mounted on
nfs/dataset1 48T 25T 23T 51% /mnt/dataset1
nfs/dataset1/dataset2 23T 201K 23T 0% /mnt/dataset1/dataset2

Any idea how can i overcome this scenario?

Can you post zfs mount results (run at server)

edit: and mount results run at client.

I can't understand why I can't see dataset1 nor dataset2 in the output you posted...

Btw1 please put output within CODE tags

Btw2 maybe post results of zfs list, run at server...

This is totally normal and correct. You have to share each dataset individually.

I've updated the output reply with the data you requested.

Thanks!

So what is the point of allowing me to create a sub dataset?
If you can you point me to ZFS reference as well, that would me great!
