Summary of the issue you are facing:
I already have several Nextcloud instances running for different use cases (including for different people etc.)
So far I have not had such an error.
Yesterday I set up a brand new instance of Nextcloud. As always, I used the standard configuration (installation of the web server, PHP, … + basic settings such as “max_upload_size” etc. increased).
However, when testing the instance (before I released it for daily use) I encountered a very strange error.
The server itself is running normally and there are no recurring errors etc. in the error log.
The configuration is as follows:
User A
User B
User C
Standard admin user
Group 1
Group 2
Group 3
Standard Admin Group
User A is a member of all groups.
User B in group 1 and 2
User C is only in group 1
I then set up a group folder using the “Groupfolders” app.
Initial configuration:
Group 1 = read rights
Group 2 = read rights
Group 3 = All rights
Advanced permissions activated.
Group 1 also has read-only rights in all subfolders
Group 2 has all rights in some sub-folders
Group 3 has all rights in all sub-folders
No quota (i.e. unlimited) was initially set for the entire group folder.
With this setup I also tested the group folder at the beginning → Everything worked as it should.
A few hours later, the person I set up the instance for asked me to limit the maximum available capacity of the folder to 512 GB for the group folder.
I made this setting under Administrative Settings → Group Folders → [Corresponding Share] → Quota → 512GB.
After the setting was made, the person contacted me again an hour later and told me that it was no longer possible to upload files >500-600 MB to the group folder.
After an initial analysis, I was unfortunately unable to find any error.
Among other things, I checked the configuration of the Apache server etc. again
(I had also consulted this forum for this - worked through several pages - I also searched through the official Nextcloud docs once).
After making all the settings in php.ini, apache.conf or nextcloud.conf (my configuration of the VirtualHost in Apache) as well as adjustments in .htaccess and .user.ini etc. etc., the error still occurred.
Yesterday I canceled the error analysis.
Today I started to eliminate as many errors as possible.
I tried the same on other Nextcloud instances etc.
By chance I have now just found the cause of the problem, but I can’t find a solution anywhere.
How to find the problem:
Test files:
Small files (<10MB)
Large files (3-7GB)
Very large files (25GB)
Procedure:
Create a test user
Set storage quota for user (e.g. 10GB)
Log in to the test account (incognito tab)
Upload small files → Works
Uploading large files → Works
Removing the quota
Uploading very large files → Works
–>All files have been uploaded to the user’s private area
Add to group 3 (the group with all rights in all folders of the group folder)
Uploading small files → Works
Uploading large files → Fails
Uploading very large files → Fails
Removing the quota for the group folder
Uploading small files → Works
Uploading large files → Works
Uploading very large files → Works
Adding the quota for the group folder (set to: 512GB)
Uploading small files → Works
Uploading large files → Fails again
Uploading very large files → Fails again
–>Up to this point, all files have been uploaded to the group folder
Uploading small, large and very large files to the user’s private area → still works
For these reasons, I have come to the following conclusion:
On the server side, a configuration error can be ruled out because without restarting the Apache server, the behavior changes depending on whether the quota for the group folder is set or not.
It is also possible for the user to upload large files to his private area at any time.
The behavior only occurs with uploads that have the group folder as the destination and if the quota is set for this group folder at the same time.
Steps to replicate it (hint: details matter!):
(In this step I assume that the server configuration for e.g. maximum upload size, maximum post size and timeout, … are configured accordingly big and that these are also applied.)
For the Upload-Part use a Browser of your choice or use a Web-Dav connection.
- Setup Nextcloud
- Create a Test user (with or without a quota doesn´t matter)
- Install Group-Folder App
- Setup a Group Folder (without a quota)
- Upload any file with any size to the Group-Folder (works!)
- Setup a Quota for the Group Folder (does not matter how large as long as larger as your max. Test-File-Size)
- Try to Upload small files (<10 MB) into the Group-Folder (works!)
- Try to Upload a big file (e. g. 2 GB) -->Fails!
- Disable Quota for the Group Folder
- Try again to upload a big file → Now it works again!
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
I could not find any logs that matter. Only Standard Nextcloud log (I have compared the log files of the “error” server with the log files of the other Nextcloud servers i run - it is (except for IP etc.) the identical log without any warnings, errors, …)
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
No errors in Web-Browser Console - even tried to use Firefox, Chrome, Edge, Opera as well as a Web-Dav Connection. Always the same behavior as descriped.
Web server / Reverse Proxy
