Share links not working from SMB storage

[chrisbeardy]

When issuing a share link from a file or folder that is located on a SMB external storage, a user is presented with the following error message when following the link:

File not found
The specified document has not been found on the server.
You can click here to return to Nextcloud.

The error only occurs when sharing a file located on SMB storage, share link can be created if the file is located locally on server.

Steps to reproduce

1. Share a file that is located on a SMB share using 'Share Link'.
2. Follow link and enter password if required
   3.See error message

Expected behaviour

When following link, should see page to download file.

Actual behaviour

Error Message

File not found
The specified document has not been found on the server.
You can click here to return to Nextcloud.

@chrisbeardy How is the SMB storage mounted?

[chrisbeardy]

I used the browser to add the storage as the picture below.

It appears in the files as seen below

Is this what you meant?

[MorrisJobke]

Is this what you meant?

Yes. Just wanted to be sure, that the username and password is actually configured and not the sessions username and password feature is used (because then the above behaviour would be the only possible).

@icewind1991 @schiessle @rullzer Ideas?

[github-tomster]

unfortunately i have to confirm this error on my setup.
smb share to a folder (not the root of a drive, i have seen that issue).
i jumped on the nextcloud train with a fresh install from techandme.se
before i had an owncloud 8 with the very same share and no issues like this. :-(

[MorrisJobke]

cc @schiessle @rullzer @icewind1991 sharing issue with external storage, any idea?

[MorrisJobke]

@chrisbeardy @github-tomster Do you have any chance to test the Nextcloud 12 beta 3 for this issue?

[rullzer]

Let me see if this happens for me as well

[rullzer]

Doesn't happen for me...
@chrisbeardy do you logs show anything?

[chrisbeardy]

I attempted again to share a link from SMB and can still see the problem, after generating the link and then trying to access it, the log does not register any event after the error.

I have practical work around at minute, involving copying the file to a location not stored on SMB but this is not ideal.

Still on V11, trying 12 beta 3 as developer is not a good idea for me, I am not able to get involved with this really, not my programming area. (I know that does not seem helpful).

[github-tomster]

actually it is not possible to reproduce the error: 'storage not available' or 'File not found'.
though the machine NC is installed on had several updates the last days.
among these updates there was: apache2-data:amd64 (2.4.18-2ubuntu3.1, 2.4.18-2ubuntu3.2)
maybe that was relevant?

[github-tomster]

ok. as right now i tried again.
and it seems more than strange i try to describe
logged in with admin accound,
checked the external smb storage
it states green so i guess it is mounted correctly.
calling the share-link
site builds up and says: file not found.
went back on the admin-login to check the file.
calling files home,
clicking the name of the external storage
an it tells me i dont have permission to upload files here.
since i just clicked the folder i expected to see the content. confusing.
right after that i checked the logs,
guess what: no entry!
checking the apache2 log just reveals a 404

on the machine holding the share i can see an successful security eventlog entry.

refreshing the browser-window with the admin login leads to
correct acces to the files again. and refreshing the link window
on the testing remote machine accessing the shared link can access it now.

EDiT 8hrs later:
meanwhile i have made and update to NC12
and lucky me has some error log entries now!

[github-tomster]

ok, here i am again.
i have found: https://docs.nextcloud.com/server/11/admin_manual/configuration_files/external_storage/smb.html
there it states:
The SMB/CIFS backend requires smbclient or the PHP smbclient module to be installed on the Nextcloud server. The PHP smbclient module is preferred, but either will work. These should be included in any Linux distribution. (See PECL smbclient if your distro does not include them.)
to me this reads either smbclient OR and not AND php-smbclient-module.
on the machine was no smbclient package installed. now it is.
as expected the errors: "Can't find smbclient binary in path\" are gone now.
i will report back if the shares are always available from now on.

[github-tomster]

shared a folder yesterday.
went on a remote machine

EDiT#1:
i also found the php error:
fread(): \Icewind\SMB\NativeStream::stream_read - read -8193 bytes more data than requested (-1 read, 8192 max) - excess data will be lost at /var/www/nextcloud/apps/files_external/3rdparty/icewind/streams/src/Wrapper.php#83

EDiT#2:
when i try to access the share a couple of minutes after that, it works...

what logs would be helpful also?

Update to this, been a while, I seem to be able to share now but I too get a lot of php errors constantly forming:

It's been a bigger while now, do you still have those errors? :)
