All files invisibe using the App

Server
1

Hi all,

I am having issues with my OwnCloud instance:
I can see all the files fine via browser, and very unreliably when using the app.

  • Browsers work fine
  • iOS and Android Apps show empty folders (very very often)
  • Official Android and forked Android App show this behaviour
  • All shares are affected

Using the exact same devices, but using the built-in browser instead of the app everything works fine.

  • The OwnCloud instance runs on 10.0.6 and is hosted on a Debian 8.7 Server
  • The users authenticate agains a Windows Active Directory
  • Files are accessed by using an external share

What could be causing this?

Here are two excerpts from the log file:

Hi,

it looks like owncloud has issues accessing the external storage. What kind of storage are you using and how is it configured?

Hi,

I am using a Windows W2K12R2 fileserver that hosts the shares.

OwnCloud is configured as follows (I try to explain it as detailed but short as I can)

  • SMB / CIFS
  • Authenfication by username and password
  • IP and Sharename(s) of the remote fileserver

The shares are mounted by an dedicated user, one for each share respectively:

  • Share 1 is mounted by user owncloud_1
  • Share 2 is mounted by user owncloud_2
  • Share 3 is mounted by user owncloud_3
    ..

and so on and so forth.

  • The Shares are made accessible for a user group defined in OwnCloud
  • The OwnCloud groups are populated with users from the ActiveDirectory

One share however is configured unlke the others:
We provide the users that log onto the OwnCloud their personal share , which the same fileserver provides
Here the configuration is as follows:

  • Foldername: Homes
  • SMB / CIFS
  • Store credentials in session
  • IP of the fileserver /$user

This share is (according to the customer) the ONLY directory that does not have the issues of not displaying files.
All of the other shares do have this issue.

I hope I could make clear, what my coniguration looks like.

Regards

Hi,
in the meantime I found out, that when I disable the crontab entry added by OwnCloud everything is smooth and works as it should.

So I presume that one of these entries in the oc_jobs table is causing the errors the end users experience.

  • How can I disable jobs in this table?
  • Which of these jobs may cause my errors?

  • How can I delete jobs in that table?
