SMB File Share enumerating everything as folders

[wilhil]

Steps to reproduce

1. Installed a Windows Server 2016 Test Environment - Domain Controller, File Server, Win 10 client, Nextcloud on Ubuntu following install guide.
2. Setup a SMB file share pointing toward the file server

Expected behaviour

I should see all files and folders listed.

Actual behaviour

Everything appears as folders - if I click on a folder, it enumerates. If I click on a file, I get an error and it takes me back to the first page after login.

Without access to your command line download the data/owncloud.db to your local

Summoning @icewind1991 as this might be his area of expertise

[icewind1991]

Can you try connecting to the smb share using smbclient and then positing the output of ls here

[wilhil]

It download the text file fine - no EOL character, so, prompt came out on a same line straight after.

Appears to look all correct? - And sorry, I'm a sysadmin, but, never used Samba/smbclient directly (other than indirectly on a NAS/appliance)... Please let me know if I did it wrong or if I should be testing another way

[wilhil]

Ok - I am totally confused.

Still getting this issue, but I wanted to experiment as I really want to get this working.

The main shared folder is on a DFS root, I thought maybe that is causing issues (I remember a SAMBA bug a few years ago).

I created a new share outside of DFS - Works fine.

I created a subfolder called test in DFS - Same bug.

I created a subfolder called test2 in DFS, Set external storage from / to /test2 - the share works fine

I then changed external storage from /test2 to / - now when I browse, I can go to the test2 subfolder fine, but everything else returns the same bug/problem...

After a few minutes, I go back/hit refresh - I now have the same problem and all files are showing up as a directory again

Any advice? Is DFS shares just not supported or is there anyway to get this working?

[icewind1991]

@wilhil can you also post the output of allinfo from one of the files that show up as folder

[wilhil]

@icewind1991 - Sorry, please can you give a bit more info - is that a smbclient command or something else? I'm looking/experimenting now...

[wilhil]

@icewind1991 -

This is for the two files in the root - I am guessing the attribute D is the problem? SMBClient does allow me to download and view the files fine (well, only tested with a few text files) as the earlier picture shows.

This looks more promising in a non DFS share coming from the same server.

Any idea what is causing this?

[necrevistonnezr]

I have the same issue when accessing my Nextcloud via WebDAV using an iOS app like Documents or Goodreader. DOCs and PDFs are shown as folders when in a subfolder:

The first screenshot shows the first level of the sync folder "CM" - everything is fine (PDFs are shown with the right icon, no file extension. And they actually open).

The second Screenshot shows a subfolder called "2007.09. ..." with PDFs. Instead of the files, folders are shown with the files' names and a ".pdf" extension. If you click on the folders, it's shown empty.

[jospoortvliet]

Maybe there's a way @icewind1991 could get access to a server that has this issue from somebody who experiences the bug? Or can you reproduce it, Robin?

[necrevistonnezr]

I can provide access - just let me know.

[jospoortvliet]

@icewind1991 ping ;-)

[BlackEdder0815]

I think, this issue is still open?
I tried to connect my nextCloud to a webdav of pCloud. Same behavior here: all files are recognized as folders.
If I mount this webdav via windows, all works fine. Seems to be a rendering-problem, so that all items wer recognized as folders.
Also: It seems, that this is related to #5543 - only just the other direction.
There was a bug in the related sabre-dav lib. Maybe this is the same, and files_external is still using a buggy one?
@icewind1991 any suggestions?

[skjnldsv]

As I cannot reproduce the original issue anymore using latest samba, I will close this ticket. If this is still happening please make sure to upgrade to the latest version. After that, feel free to reopen.

[wilhil]

I had a look a couple of months ago and it was still happening. Please note, for me originally, this was not an issue with SMB itself, it worked fine when mounting directly at the CLI. this seemed strictly to be an issue when going to a DFS share.

[skjnldsv]

DFS share

Define DFS?
Thanks for helping on this issue :)

Windows Distributed File System - https://docs.microsoft.com/en-us/windows-server/storage/dfs-namespaces/dfs-overview

At large clients, we typically use a DFS over a standard file share for redundancy. I always thought the DFS was simply server to server and clients connected the normal way.

In fact, Linux/Mac clients seem to work fine, as do many third party tools (As you can see above, I used cat on a file without issue)... It's purely nextcloud for some reason sees the files as folders!

[skjnldsv]

Thanks! :)
