FTP Server - Dataset issue

[yessey]

Hello everyone!

Here's what I have:

FreeNAS v. 11.3-U3.2

I've setup FTP Server. Created a group/user and two datasets "office","Scan". "Scan" is child dataset & there's several files in it. So when I try to delete Dataset folder "Scan" in Filezilla i got this message "550 Scan : Device Busy", I can't delete the folder It's Ok! But! that files in that folder gone away. Is this a bug or permissions issue ?

Neither. ZFS won't allow ordinary Unix removal mechanisms to delete datasets. Since Scan is a dataset, the only way to delete that is from Storage->Pools, then clicking on the 3 dots next to Scan, and selecting Delete Dataset. You can also delete it from shell via zfs destroy <parent pool>/office/Scan or whatever the path to Scan is.

Hello!

Thank you for Your response. No, I know how to delete datasets generally. My issue is about - Why files in dataset goes away when I try to delete dataset folder in FTP client ?

Because deleting a folder in FTP issues rm -rf behind the scenes, but the rm fails to remove the "folder" as it's a dataset.

Ok, I got it. So is there some solution ? SMB only ? Only Windows clients

I don't understand what you're trying to accomplish. Are you trying to protect the files within the dataset from deletion? Or are you trying to delete the dataset?

I'm trying to protect the files in dataset from deletion, if anyone tries to delete dataset folder.

See http://www.proftpd.org/docs/howto/Limit.html. You'll need to create something like this in the FTP service Auxiliary parameters:

Code:

<Directory /mnt/path/to/Scan>
  <Limit DELE>
    DenyAll
  </Limit>
</Directory>

Thank you! This is very useful! What if I want to protect deletion ONLY specific directory ? I try to delete directory "Scan" then I got "permission denied" message, but I can delete every file in that directory :)

The limit statement applies to all files within that directory statement.
